Cell phone battery overcharge can lead to battery explosion?

Mobile phone The battery Overcharge is that people often meet in daily life, because many people believe that keep full charge state for mobile phone is the best, but actually let cell remained full of state power, or keep the cell phone battery overcharge, can cause damage to the battery itself.

Before when buy a new mobile phone salesman will always remind you that a new mobile phone to put all of the electric charge 12 hours later, and then completely discharge, repeat the above steps 3 times. And now, to use The lithium battery Era. In fact already did not need to bother battery maintenance process.

Because of the need for multiple discharge is Ni-MH battery charging, the battery has a strong ability to remember, repeated charging and discharging can let the battery charge gain maximum limit. But for the Lithium electricity Pool, there is no need for the memory of this complex process. The lithium battery will always maintain the highest power limit?

Of course not. Because lithium battery is durable, but after several times of cell cycle filling process, will be on the upper limit of power loss, and loss of the culprit is the cell phone battery overcharge.

So-called cell phone battery overcharge, which means that in the case of mobile phone display power is full to cell phone battery recharged. Overcharge behavior for lithium battery damage is very big, but along with the potential risk is very big. When overcharge occurs, the current transformation of heat energy is large, and thus lead to the reaction of lithium battery cathode electrolyte, consumes the largest electric capacity of lithium-ion batteries, when heat accumulated to a certain degree, will be on fire and explosion.

The real life many charging to mobile phone explosion cases often occur, a big reason is the battery itself quality problem, the charger IC not protected. So in order to improve the safety of the battery, prevent overcharge, a lot of mobile phones have the existence of IC protection, the charger itself also to monitor voltage and current.

But it doesn't matter how much manufacturers bring battery safety is high, we are still on the phone if the battery under the condition of not unplug the power, keep the cell phone constantly repeat the process of discharging and charging, still can reduce the electric capacity limit. And this kind of mobile phone battery overcharge, will directly affect the service life of the battery, including the use of the cell phone, and let the mobile phone is wanton overcharge, believe in less than a year, the battery is about to die.

Want to fundamentally prevent overcharge or laid hands on him from the time control. So, good habit is to have a chance to plug in charge, charge to pull the same time as the - a few much food, but don't eat too full. Second, should try to reduce the time of the battery full charge state. After filling the electricity remember to pull the plug.
