Lithium ion battery is a kind of secondary battery (rechargeable battery), which mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work.
1. How to charge a new battery
In the use of lithium batteries, it should be noted that the battery will enter a sleep state after being placed for a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened.
But the lithium battery is easy to activate, as long as 3-5 normal charge and discharge cycles can activate the battery and restore normal capacity.
Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process.
2. When should charging start in normal use
You can often see this statement, because the number of charging and discharging is limited, so the battery of the mobile phone should be used up as much as possible to recharge, in fact, the life of the lithium battery has nothing to do with this.
Do not charge the mobile phone lithium ion battery too full or use it to the point where it is dead. Charge the battery before it is used up. It will not cause damage to the battery. Charging should be within 2-3 hours, and it does not have to be fully charged. However, you should fully charge the lithium battery 1-2 times (normal charging time) and discharge it every 3-4 months or so.
Lithium batteries that have not been used for a long time should be stored in a cool and dry place, with a half-charged state. Fully charged storage is dangerous and the battery will be damaged, and the battery will be destroyed if stored without power. Every 3-6 months, check whether you want to recharge.
Lithium ion batteries can be divided into liquid lithium ion batteries and polymer lithium-ion batteries according to the electrolyte. The electrolyte of polymer lithium-ion batteries is colloidal and will not flow, so there is no leakage problem and it is safer.
The charging voltage shall not be higher than the maximum charging voltage when charging, and the minimum working voltage shall not be lowered when discharging.
Lithium-ion batteries must be kept above the minimum operating voltage at any time. Over-discharge or self-discharge reactions at low voltages will cause decomposition and destruction of lithium ion active materials, which may not necessarily be reduced.
Any form of overcharging of lithium ion batteries will cause serious damage to battery performance and even explosion. Lithium ion batteries must avoid overcharging the battery during the charging process.
Do not often deep discharge and deep charge. However, after about 30 charging cycles, the power detection chip will automatically perform a deep discharge and deep charge to accurately assess the battery's status.
Avoid high temperatures, which may shorten the life span, or cause an explosion in severe cases. If possible, store in the refrigerator. If the notebook computer is using AC power, please unplug the lithium ion battery bar to avoid being affected by the heat generated by the computer.
