Do you know the correct way to use lithium battery?

The first, the lithium battery correct charging methods:

Chemical properties of lithium is very active, easy to burn and when the battery discharge and recharge, inside the battery will continue to heat up, produced by gas expansion in the process of activation, the battery internal pressure increase, pressure reaches a certain extent, such as shell have scars, which will burst and cause leakage, fire, or even an explosion.

1, charging:

Lithium electricity safe working voltage range is from 2.8 V to 4.2 V, below or above this range of lithium ion battery voltage is very unstable, or even cause an accident.In order to ensure the battery in a safe range, so we need special charger.The charger will automatically based on the current battery status and adjustment.

2, activation:

Charger before charging, in small current supply batteries, and detect the battery voltage change at the same time, and gradually increase the current until the set value.This process can be regarded as a kind of activation or test charge.

3, constant flow pressure:

The charger to recharge the battery at a constant current, with the increase of the battery voltage, the charger at the same time increase the charging voltage, to speed up the charge.

4, variable flow constant voltage charging:

When the battery reaches 4.2 V voltage, the battery into only about 70% of electricity (not full).At this time the charger is at A constant voltage, the smaller current for the battery to charge, value to less than 0.1 A charging still detected didn't stop charging when the battery voltage continues to rise.

Second, the preservation of the lithium battery voltage model

Lithium battery is commonly model lithium polymer battery, its safe use of the lowest voltage is 3.6 V, but in order to ensure that the battery will not damage due to excessive discharge, generally the lowest minimum TVC using voltage of 3.7 V, the maximum charge cut-off voltage of 4.2 V, the highest voltage, battery energy storage for peak, if long time without the use of high voltage, there will be a reaction to produce gas in the lithium battery monomer to generate and began to gather, time grew to lithium battery is bulging, commonly known as "big belly", in order to avoid the happening of this kind of condition, the model of lithium-ion batteries store general control voltage from 3.7 V to 3.8 V.

Third, lithium battery storage conditions

Model of lithium battery storage condition is the most critical temperature and humidity, usually at room temperature for a little effects on the state of the lithium battery, but you can't have the sun point-blank, high temperature easy to cause the model to summon the lithium-ion batteries or explosion, so general will model the lithium battery storage to avoid light breath tin box or plastic box, if a single model of lithium battery discharge performance is very good, also need to purchase a model lithium battery explosion protection bag, this kind of strengthening bag internal net, can prevent high-energy lithium battery explosion in the event of a leakage model cause harm to other items.
