Everyone knows that most of our mobile phones and computers use lithium-ion batteries, but do you know whether there is a memory effect after charging a lithium-ion battery?
First of all, what is the memory effect of the battery?
To put it in the simplest terms: the battery seems to remember that you only used part of its storage capacity-in the end it no longer provides all the energy.
How did this happen? What harm does it do to the battery?
This is caused by the incomplete charge-discharge cycle, which causes the battery’s working voltage to drop over time. This means that although the battery is still discharging, the voltage it provides is sometimes too low to drive related equipment. Therefore, the memory effect has two negative consequences: first, the available capacity of the battery is reduced, and secondly, the correlation between the voltage and the state of charge is shifted, and the latter cannot be reliably determined based on the voltage.
Let’s talk about today’s question. Does the lithium-ion battery have a memory effect after charging?
One of the advantages of lithium-ion batteries is that when the battery is repeatedly charged when the battery is not fully discharged, there is almost no “memory effect” that reduces the maximum charge capacity, that is to say, there is no memory effect. Therefore, even if you start charging with the remaining power (additional charging), it will not affect the maximum charging capacity, so don’t worry.
