Advantages and Limitations of Lithium-Ion Batteries

 There are different forms of lithium-ion batteries depending on the materials used in the internal and external composition of the battery. These materials determine the performance and capacity of the battery. However, despite the differences, all lithium-ion batteries share characteristics that make these batteries more reliable than other types of rechargeable batteries. From having higher energy density to faster charging rates and longer lifetimes, lithium-ion batteries are considered better and therefore more reliable in commercial applications.

What are the advantages and limitations of lithium-ion batteries?

All types of lithium-ion batteries offer users a variety of advantages and limitations compared to other rechargeable battery types. Let’s take a look below!

Benefits of Lithium Ion Batteries:

Extended service life

The life of a battery is determined by the number of charge and discharge cycles it can handle throughout its service time. Low-end lithium-ion batteries can manage hundreds of charge cycles, while regular variants can hold over 1000 cycles before losing about 30% of their original maximum capacity. The highly advanced version of the Li-Ion battery is capable of handling up to 5000 charge-discharge cycles, allowing it to last longer than other battery types.

faster charging

Li-Ion batteries have been shown to charge faster than Ni-Cd and Ni-MH batteries or rechargeable alkaline batteries; it all depends on the hardware specifications of the device using the battery and the mAh capacity of the Li-Ion battery, a fully charged The effect is about one to two hours.

Improve energy efficiency

Energy efficiency may be the main benefit of using lithium-ion batteries compared to other types of rechargeable batteries. Since the battery has a higher energy density than other batteries, relative to its physical size and low self-discharge rate, energy efficiency is improved.

smaller

Lithium-ion batteries have a higher charge capacity relative to their physical size, so they can store a lot of energy in a small space. This makes them more portable and smaller than other battery types. Portability makes it easy to use in traditional consumer devices such as smartphones and laptops.

Limitations of Li-Ion Batteries:

high manufacturing cost

Lithium-ion batteries tend to be expensive to produce as batteries can cost around 40% more to manufacture than NiMH batteries. Factors such as expensive on-board computer circuits that regulate the voltage within a safe range contribute to this hefty price tag.

Security risks

Over the past few years, lithium-ion batteries have been reported to be a safety hazard because they are prone to overheating. This overheating can lead to thermal runaway, igniting a flame that can further lead to an explosion.

aging defects

Regardless of whether the battery is in use or not, once it leaves the factory, the battery starts to deteriorate, which is called the aging effect.

Is there a better battery than Li-Ion?

In fact, breakthroughs that could replace lithium-ion batteries are already known, but since they haven’t been incorporated into commercial use like this one, we can’t say anything better at the moment. Lithium-ion batteries will continue to be reliable for a while now, and there doesn’t seem to be any rush to leave.

Solid state lithium battery

This type of battery is capable of operating at supercapacitor levels, allowing users to fully charge or discharge the battery in less than 10 minutes. They provide maximum stability, but at the expense of electrolyte transport. This feature makes solid-state lithium-ion batteries suitable for electric vehicles because they are safer and more stable than current batteries. The battery technology can adapt to temperatures as low as -30 degrees Celsius to 100 degrees Celsius. While solid-state batteries have not yet been perfected for commercial use due to problems with electrolytes, they appear to be an excellent opportunity to improve lithium-ion batteries.

foam battery

Prieto Battery Company has outdone itself by inventing a battery that uses a copper foam compound. Due to the use of a flammable electrolyte, the battery is expected to provide the highest safety conditions. They will also offer longer lifetimes and faster charging with faster charging and greater energy density than lithium-ion technology. Compared to current battery technology, foam batteries are expected to be cheaper to manufacture and lighter in weight. However, the battery is not yet perfect, but something will be ready for it in the future.

When should I charge my Li-Ion battery

 Your battery is a rechargeable battery with a limited lifespan. These batteries gradually lose charge and sometimes take more time to recharge. If you want to extend the life of your batteries, you need to take good care of them. This means you should develop better charging habits and pay attention to battery storage. Below we will share some basic charging tips for Li-ion batteries.

Is it better to keep Li-ion batteries charged?

Yes, it’s best to keep the Li-Ion battery charged. You can take care of the battery in these ways. You can leave your device powered up overnight.

This won’t be a huge problem if you don’t unplug the device right after charging it. That charger is smarter than you might think. You can leave the charger plugged in overnight or even all day. The charger will stop charging as soon as it is fully charged.

Charge your device as much as possible.

Lithium-ion batteries don’t respond well if you charge them and then use them to the last drop. If you charge them at appropriate intervals, you’ll get a good response from the battery.

Don’t let it get overcharged.

The biggest danger to your laptop battery, phone battery, and tablet battery isn’t overcharging, it’s heat. With that in mind, if you can, it’s a good idea to remove the laptop’s battery while it’s plugged into the wall. The trick is that if you’re using your computer without a battery, you’re in danger of shutting down in the event of a power outage or an unsuitable power adapter. Weigh your preferences.

If you can’t or don’t want to drain your laptop battery, at least make sure you have good airflow. Do not block cooling vents. The fan can even be pulled up with the stand.

Do Li-Ion batteries need to be fully charged the first time?

unnecessary. You don’t have to fully charge a Li-Ion battery the first time. Lithium-ion batteries have the highest usable range from the start, and a 1st charge is no different than a 10th charge.

All you need to do: Just plug in the charger and get started.

Normal use

Lithium-ion batteries have a lifespan of at least 300-500 charge and discharge cycles, typically 2-3 years. Throughout the life cycle, lithium-ion batteries typically experience capacity loss due to a variety of factors, including charge cycles, storage, temperature changes, usage patterns, and overall aging. To limit the risk of damaging the battery, use only the designated smart charger.

Hot and cold weather use

Lithium-ion batteries are comparable to humans in that none of them behave exactly the same, and they operate best at temperatures that are not too hot or too cold.

These batteries operate better at high temperatures than at low temperatures because heat reduces physical stability and speeds up chemical reactions inside the battery. A side effect of this method is that it puts stress on the battery, which can result in a shorter lifespan with continued use in hot conditions.

What’s the best way to charge a Li-Ion battery?

Charge your device

If your battery is at or below 50%, plug in the charger. You only need to charge your device’s battery when it’s fairly low, as having a fully charged battery all the time won’t enhance your device’s capabilities. If you want to check your device’s battery, look for the small battery icon in the menu bar. If you’re on a laptop, float over the icon to see the percentage. If you are using a smartphone or tablet, click the icon or expand the menu to see the percentage meter.

Do Li-ion batteries need to be fully charged for the first time?

 Lithium batteries are the main batteries in laptops, smartphones, iPads, PDAs and power banks. These are standard batteries because they are the most energetic rechargeable batteries available today. Lithium-ion batteries are very popular. Now we know what a lithium battery is and where it can be used. But have you ever thought that the lithium battery must be fully charged before it can be used? Or how does a Li-Ion battery last without charging? How do you care for your lithium-ion battery? Whether this is the answer you want to know, the answer will be told below.

Do lithium-ion batteries need to be fully charged before first use?

You do not have to fully charge or discharge the battery during its first life cycle. Lithium-ion batteries have maximum capacity at the beginning and on the first charge, no different from the tenth charge.

Discharging and recharging is better than a fully charged one because a less charged battery puts less stress on the battery as it helps it last longer, but these are not reliant on modern batteries. But don’t remember to not let the deice plug in once you’ve fully charged your battery. Instead, just follow shallow discharge and charge cycles.

Batteries have built-in protections that prevent them from exploding if they maintain their maximum capacity. You should allow shallow discharge as its charge will reach the sweet spot for longevity. Therefore, you should allow the battery to fully discharge up to 5% to recalibrate its self-assessment. This mechanism is great for laptops and smartphones and gives you an “estimated battery time remaining”.

How long can a lithium-ion battery last without charging?

Batteries do require routine maintenance and care in use and handling. Lithium-ion batteries can last 2 to 3 years without recharging if you follow these points:

1. You should not leave the battery unused for a long time, whether you are using it or storing it.

2. These lithium-ion batteries have a limited lifespan and gradually lose their ability to maintain a charge. This loss occurs gradually and is irreversible.

3. Lithium-ion chemistry prefers partial discharge over deep discharge, so it’s best to avoid dropping the battery all the way down to zero.

4. Li-ion has no “memory”, so you can’t harm the battery pack without partial discharge. When a lithium-ion battery drops to a certain level, it is destroyed and the lithium-ion battery ages.

How to care for lithium-ion batteries?

1. Keep the battery at room temperature: You should always keep the battery at room temperature between 20 and 25 degrees Celsius. The worst thing that can happen to a Li-Ion battery is that you should fully charge it before leaving it at room temperature. Just remember not to leave your phone in the car or any other boiling place. Because heat is the most important factor in shortening the life of lithium-ion batteries.

2. Consider using a high-capacity lithium-ion battery instead of carrying a spare: Batteries will degrade over time, whether they are in use or not. So, the extra battery won’t last longer than the battery in use. Don’t forget about aging characteristics when buying batteries, be sure to buy recently produced batteries.

3. Allow partial discharge, but don’t let the whole battery drain: Li-ion batteries have no charge memory. This means that deep discharge cycles are not required. Batteries use partial discharge cycles.

4. Avoid complete discharge of lithium-ion batteries: The battery’s built-in safety circuit is turned on, and the battery will feel as if it is dead even if the original charger is not used. Only battery analyzers with a boost function have a chance to charge the battery.

5. When storing, discharge the Li-ion battery to 40% and store in a cool place: the original battery will not add extra battery. The oxidation rate of lithium ions is higher.

Should Lithium Batteries Be Fully Discharged – Quick and Correct Discharge Method

 A discharge or charge cycle refers to the complete discharge of a battery after charging. However, the battery is never fully discharged. Manufacturers use an 80% depth-of-discharge formula to rate batteries. For this reason, 80% of the available energy is delivered while 20% is retained. In addition, the manufacturer claims that the life of the battery increases when the number of cycles of the battery falls below a full discharge. Lithium technology can also cause extreme heat generation and internal short circuits.

Can a lithium battery be fully discharged?

Lithium batteries are not suitable for deep discharge, as everyone knows. Generally, the fully charged voltage of a lithium battery is about 3.65V, and 20V is the fully discharged voltage. This means that overcharging will bring more energy to the battery, thereby destroying the battery. Damage can be extreme and caused by shooting.

Most devices today use lithium batteries that have no memory effect. Always try to partially discharge to around 40% to 70% before charging the battery. Conversely, you should not leave the battery fully charged for extended periods of time. This will reduce lifetime and capacity loss. If you want to keep it for six months, please charge 50% before storage. However, if you use it a lot, you don’t need to be nervous.

Shallow discharges only cause minor problems. For example, a PC might get confused and display the wrong battery percentage. Laptop manufacturers recommend that users perform a full discharge once a month. It will assist in measuring the battery of the device based on the estimated time. Do not leave the battery in a deeply discharged state for an extended period of time. Batteries cannot discharge to zero, but if they do, charge them as soon as possible. Avoid leaving an uncharged device without charging.

What is the fastest way to discharge a lithium battery?

Most modern lithium batteries have internal circuitry. This prevents them from discharging deeply, which can lead to battery damage. You can discharge them to C/10 until no current flows. Let’s say they are 5Ahr and can discharge to 500Ma. Most battery packs have the same C/10 rate.

A resistor or LED can discharge the battery safely and quickly. You need to make sure the resistors are rated above the 100mA spread. If you need a 2W resistor, add a fuse to produce 200mA. By ensuring process safety, resistors are the right choice. The cool stuff keeps the insulation from melting and damaging the battery. It provides enough resistance to keep the temperature cool.

How much can a lithium battery discharge?

It is recommended to store lithium batteries to 40% discharge. It’s safe if you’re going to keep it long term. If it is held at full charge, oxidation will be at a high rate. Additionally, lithium batteries have a safety built-in circuit that turns on when their discharge voltage falls below 2.5 volts. Do not discharge the battery beyond the manufacturer’s instructions. Finally, a deeply discharged battery should not be charged immediately, especially if left in that state for an extended period of time.

Lithium batteries have no charge memory effect. Use partial discharge instead of deep discharge. Lithium battery experts suggest that it can be fully discharged after 30 charges. Continued partial discharges can cause digital memory and degrade the accurate performance of the device.

Lithium battery discharge guide

1. Never discharge a lithium battery at a higher amperage rate than the specific label on the battery

2. The battery temperature should not exceed 140 degrees Celsius. Cool the battery while discharging.

3. The battery should not be discharged below the marked voltage. Discharging below recommended voltage can damage, degrade performance and cause fire.

4. The discharge voltage of lithium batteries in each battery should not be lower than 3V. Follow the cut-off voltage.

5. Keep an eye on the battery and monitor for potential problems that may arise

6. If something goes wrong, stop the process immediately. Put it in a safe place and assess the problem.

7. Check the condition of the battery. If the battery is not properly balanced or swollen, stop using it. The safety of your equipment is in your hands to avoid accidents.

What do I do with my old lithium batteries – here’s what to do

 The superior performance of lithium-ion batteries, to a large extent, explains the superior performance of most electronic devices. However, special attention should be paid to lithium batteries as they age over time. If these batteries are handled in the wrong way, fire, contamination, and other negative effects may result. To prevent this negative effect from happening, you should do something to properly dispose of the battery.

They are listed below:

1. Make sure the battery is removed from the unit and away from the main unit before further material recycling.

2. If the battery cannot be easily separated from the device, consult an expert to remove the battery. Experts should be properly licensed in their facility.

3. After removing, the battery terminals should be insulated to avoid short circuit.

4. Batteries should be stored in UN-approved buckets or boxes, separated by dry sand and vermiculite.

5. Batteries with damaged packaging, leakage or swelling shall be processed according to the above-mentioned UN-approved barrel packing process

There are also things you shouldn’t do when dealing with lithium batteries.

Lithium-ion batteries cannot be subjected to the following treatments, which include:

1. Lithium batteries are disposed of with regular garbage.

2. Squeeze, puncture, throw or do anything that could cause the electrodes to contact and short circuit

3. Mix damaged and undamaged batteries

4. Putting a large number of batteries together without proper isolation as this may cause a fire hazard

5. Place batteries or products containing batteries in any process not specifically designed to contain batteries

6. Store discarded lithium-ion batteries at home, as these batteries are prone to short circuits and catch fire.

Lithium batteries contain a variety of chemicals. If it is not handled properly, it will cause serious consequences, such as environmental pollution and resource loss. Lithium has high activity and is difficult to control. Effects such as high temperature, high charging voltage, short circuits, and even excessive pressure can cause exothermic reactions that release energy through light or heat in the battery.

Lithium batteries contain a polypropylene film that separates the electrodes and prevents short circuits. Therefore, if the device is crushed or punctured, a thermal event can result, as the battery shorts out when the thin-plate separator between the positive and negative components of the battery is destroyed. The larger the battery, the stronger the thermal response. In this way, incorrectly discarded batteries may ignite other nearby flammable materials. Especially when collecting a lot of batteries, it is possible that only one Li-Ion battery will ignite.

Why Lithium-Ion Batteries Swell, The Dangers Of Swelling, And How To Fix It

 Lithium-ion batteries are the most commonly used batteries worldwide. They are mainly used in mid-range appliances such as laptops, cell phones and cordless phones. Due to their high functionality, they are used a lot. Despite their high capacity, they swell easily. This caused disdain from a lot of customers, who wondered why this was happening and if they had a way to fix it. The following will tell you, and will also tell you how to solve this problem, let’s take a look!

What causes lithium-ion batteries to swell? The reasons are as follows:

The general cause can be understood as what happens at the surface level that causes this expansion. Details are as follows:

1. The battery charging time is too long, and the stored power in the battery is too much.

2. The excess electricity causes various reactions (technical reasons), resulting in swelling.

3. In short, swelling is caused by overcharging the battery.

Technical reasons

The technical reason for the swelling can be understood as the science that happens inside the battery that causes this swelling. Simply put, they are the result of overcharging. The technical reasons are discussed below:

1. An undesired reaction between the electrodes and the electrolyte can cause an imbalance within the battery, which can lead to swelling. As we discussed in General Reasons, this imbalance is caused by too much current being directed to the battery.

2. Unwanted reactions can lead to the release of gases which, when expelled from the battery, can eventually cause the battery to swell.

3. These reactions can lead to contamination of waste particles within the battery. These particles take up more space, causing the battery to swell.

Are Swollen Batteries Dangerous?

To judge whether a swollen battery is dangerous, we have to look at swelling in two ways. Then we can take the appropriate scale to judge whether it is dangerous or not. This will help us determine our immediate response if we happen to encounter a swollen battery.

Dangerous ways of swollen batteries are as follows:

1. Since there is more power in the battery than needed, when this current reaches the components of your device, it has the potential to damage those components. It can cause burning or failure of these components.

2. There is usually a designated space for the battery in a typical device, and if the battery swells, it will start destroying the device from the inside to make up the space needed.

3. In older versions of Li-ion batteries, an overcharged (i.e. swollen) battery could explode and splash around.

Here’s how to swollen batteries in a non-dangerous way:

1. In general, some lithium-ion batteries fail if they are overcharged. This means they will have significantly less functionality and will not cause other problems.

2. Lithium-ion batteries in new devices no longer explode. This is the result of the new technology strategy employed by these batteries.

How to prevent swelling?

You just need to make sure you don’t overcharge your battery. In other words, keep an eye on your rechargeable battery and remove it when it reaches 100% charge.

What to do when your lithium battery swells? If your lithium battery swells, you can do the following:

stop the charging process

As soon as you notice (or worry about) your lithium battery swelling, you should stop charging it. Once the battery starts to swell or gets close to that point, the situation deteriorates rapidly, so action needs to be taken quickly to avoid any undue harm to the person, the battery, or the equipment that uses the battery.

Safely remove the battery

You should use the appropriate method to remove the battery. This means that you should first turn off the device, unscrew the case properly, and then remove the battery, preferably with all safety measures intact. This will allow safe removal without damaging your device or components of that device.

Properly dispose of batteries

If the battery does swell, there’s nothing you can do about it. Remember, you can’t just throw it in the trash. There are proper procedures for battery removal and you must follow local guidelines to do so. You will most likely have to hand over the battery to an authorized organization.

Replace with new battery

Since you’ve disposed of the previous battery, all you need to do now is buy a new battery. Just make sure you get the same replacement battery that you used before, as this will work best for your device.
