Do Lithium Ion Batteries Have a Memory?

Do Lithium Ion Batteries Have a Memory? 1

Whether from a technical point of view or from the price point of view, the battery has a very important position in electronic products. Till now, the mobile phones on the market has been basically completed from the NI-MH battery ( nickel-metal hydride battery ) to the Li-ion ( Lithium-ion ) battery transition. Perhaps because the mobile phone battery has just completed a revolution from the NI-MH battery ( nickel-metal hydride battery ) to the Li-ion ( Lithium-ion ) battery, so people do not have a unified understanding of the lithium battery which leads to incorrect rumor spread in the air. Therefore, it is necessary to know basic lithium battery knowledge and not spreading rumors.

Memory effect means during the battery charge and discharge process, the battery plate will produce many small bubbles, after a long time, these bubbles will reduce the battery plate area, but also indirectly affect the battery capacity.

Many people believe that lithium ion batteries in the case of running out of electricity, otherwise there may be possible to have a memory effect. In fact, the concept is from the NI-MH battery ( nickel-metal hydride battery ), the NI-MH battery has memory effect, if not run out of the power, the battery will decrease the power along with the increase using times, and later nickel-metal hydride battery have been improved, there is no obvious memory effect, because the nickel-metal hydride battery would crystallize in some degree which result in reducing capacity, it needs regular charge and discharge to maintain normal power. While the lithium ion battery basically has no memory effect, you can always charge and discharge without affecting the battery capacity.

From another point of view, the battery memory effect refers to the battery’s reversible failure, that is, the battery can be returned again after the failure performance. But lithium ion battery is irreversible, performance and capacity will only decrease along with the use, which means lithium ion battery does not have memory effect. In addition, eliminate the battery memory needs to charge deep and release deep, that is, the battery voltage needs to reach 1.0V , the mobile phone can not stick to 1V battery voltage to shut down, the nickel-cadmium battery also need some special equipment for such depth of discharge.

In summary, the lithium ion battery does not exist memory effect, the user does not have to worry about it, the birth of lithium ion battery is to eliminate the trouble of memory effect, so that we can always charge the battery without any scruple.
