The general principles that need to be followed when using lithium batteries are shallow charge and shallow discharge, that is, charge the lithium battery in time, don’t wait for the battery to run out and recharge, which is harmful to the battery’s life. Lithium batteries In addition, do not use lithium at high or low temperatures. The battery is preferably at room temperature. Temperature has a great influence on the performance of lithium batteries, so there must be a temperature regulation system. When pierced or hit hard, the lithium battery may catch fire or even explode.

The working principle of a lithium battery is nothing more than charging to store energy, and then discharging it into other energy and releasing it. When it is neither charging nor discharging, it is in an idle state. Therefore, the correct use of lithium batteries has three main aspects: correct charging, correct discharging and correct maintenance.

The correct way to charge lithium batteries

 1. At the beginning of the birth of smart phones, out of the original intention of protecting their own interests, each mobile phone manufacturer often emphasized the use of original chargers (including charging cables) to charge electrical equipment. Some manufacturers have designed special data cables but do not support them. Other chargers (including charging cables). Later, as the use of smart phones and laptops became more and more widespread, it was obvious that continuing to use this method would become a problem, so now everyone has basically unified the standard, and the charger/cable can charge different electrical appliances brands and attributes . Charging is very convenient. One problem that users should pay attention to is to try to keep the battery in normal use at all times to maintain power. Normally, when the battery is too low, mobile phones and laptops will alert you. Currently, you need to charge in time. Although low battery power will not cause a direct safety accident, long-term overuse will damage the battery structure. . Grasp the time and prevent overcharging. Although lithium batteries have excellent electrochemical performance, they will do the right thing at the right time, but anything that deviates from the equilibrium state will have safety hazards. detailed,

 2. Fill up. The interior of the lithium battery cell is also composed of many components. New batteries are ok. If it takes a long time, maybe

 The function of each component will decline, so overcharge safety risks will occur. Several typical accidents in Samsung and Apple were caused by electrical appliance owners

 People put their mobile phones next to the bed to charge them while sleeping, which may cause burns and explosions.

 3. Don’t single-mindedly and two purposes. I have experienced the feeling of using the phone while charging, especially when playing games, it is easy to feel the phone heat up. the reason is simple.

 , The mobile phone is equivalent to doing two jobs at the same time, which makes you have to pay more than twice the labor force, the body will naturally have a fever.

 The correct discharge method of lithium battery

 Charge in time to prevent over-discharge. Ordinary mobile phone users do not understand the hazards of over-discharge, because there are usually no reports of over-discharge safety incidents. versus,

 Some people even think that regular deep discharge helps maintain battery performance. In fact, this is not the case, because the memory effect of lithium batteries is negligible.

 It is said that the memory effect is eliminated in the deep discharge. Theoretically, the total cycle life of deep discharge of lithium batteries will be longer, but there is a risk of battery over-discharge

 This will cause the battery voltage to be too low and cannot be charged normally, and sometimes it takes a long time to turn on or even fail to turn on. These two shortcomings are relatively small, and the service life is relatively short.

 Pointing is better than not being able to use it, so users of mobile phones and laptops are advised not to frequently use black screens.

 Lithium battery is properly maintained

 The temperature is right, hot and cold. When idle, lithium batteries usually do not cause safety accidents. The purpose of routine maintenance is to keep the lithium battery in a suitable environment.
