How to use lithium batteries? What are the correct methods?

January 22, 2021

Lithium battery is a kind of energy storage conversion device which is more and more widely used, because its excellent electrochemical performance realizes the market application scene of small —— medium —— large. When we talk about the correct use of lithium batteries, we usually refer to small applications, that is, consumer electronics, such as smartphones, laptops. Because large and medium-sized applications are based on small application technology, small applications have common characteristics, while large and medium-sized applications are much more complex.

Usually, medium applications are on new energy vehicles, which we call power batteries; large applications are usually on base stations, which we call energy storage batteries. So when we talk about “lithium battery usage “, it is customary to limit lithium batteries to small applications.

The working principle of lithium battery is nothing more than charging to reserve energy, discharge into other energy and release, and is idle when neither charging nor discharging. Therefore, the correct use of lithium batteries on its big aspects say three: correct charging, correct discharge, correct maintenance.

Correct charging method for lithium batteries

1. should be filled. Under normal circumstances, when the power is too small, mobile phones and laptops will have a reminder, when you need to make up for electricity in time, although too low electricity will not lead to direct safety accidents, but excessive use, Over time will cause damage to the battery structure.

2. full. Lithium battery core is also composed of many components, the new battery is good, if it takes a long time, perhaps which component function will decline, so there will be overcharge safety risks.

Correct discharge method for lithium batteries

First of all, we need to understand that the memory effect of lithium battery is negligible, there is no deep discharge to eliminate the memory effect. In theory, the total cycle life of deep discharge of lithium battery will be greater, but the risk is that excessive discharge of battery will lead to too low battery voltage, can not charge normally, sometimes it will take a long time to turn on the machine, even can not turn on the machine. So to prevent excessive discharge, timely charging.

Correct maintenance of lithium batteries

The suitable environment for daily maintenance of lithium batteries should be four words: ventilation and shade. Whether the lithium battery is idle independently or in use in electrical appliances, these four words should be followed.
