Want to charge your lithium battery? These correct postures should be mastered.

As we all know, many current electronic products use lithium battery/lithium battery batteries, so for the equipment equipped with lithium batteries, its wide application makes its superior properties stand out. From everyday electronic devices such as mobile phones/computers to small electric vehicles/electric cars, the battery life and charging problems have become a topic of concern.

Wait for the electric car to recharge without electricity? Lithium battery is too late

Lithium battery, as its name suggests, uses lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution. The lithium battery we often refer to is a rechargeable lithium-ion battery, which mainly relies on lithium ions moving between the positive and negative electrodes. Come to work. Therefore, the advantages of lithium battery are high energy density, high average output voltage, small self-discharge, no memory effect, wide operating temperature range, excellent cycle performance, fast charge and discharge, high charging efficiency, large output power and long service life. It is widely used without the advantages of toxic and harmful substances.

So how to make the lithium-ion battery on the equipment of everyone's hands, such as mobile computer electric car, work more efficiently and live longer. It is very important to charge the battery correctly. The key is not to wait until your mobile phone/electric car is dead. If the device is exhausted, recharging is already "too late".

These are not alarmist, although lithium battery capacity is large / short charging time / long battery life, but also has obvious shortcomings, such as intolerance of over-discharge: over-discharge, excessively embedded lithium ions will be fixed in the lattice Can not be released again, resulting in shortened life, deep discharge is more likely to damage the battery.

Therefore, when the battery of an electric vehicle or a mobile phone is almost exhausted, or when the battery is low, the lithium ion battery may be damaged. Therefore, whether it is a mobile phone, a laptop or an electric car, it should not be charged when the battery runs out. Generally speaking, if there are conditions, it should be charged when the battery has about 40%-50% of the battery. .

Of course, it is also necessary to prevent overcharging, which would cause the positive electrode of the battery to be deintercalated with too much lithium ions, and overcharging for a long time may cause the lattice to collapse, thereby irreversibly reducing the capacity of the lithium ion battery. Therefore, it is very important to charge your mobile phone computer electric car correctly. Do not wait until there is no electricity to recharge it.
