It is superior to lithium ion battery.Since the high-tech of its own requires limitation, the company of only a few countries is being produced now
This lithium metal battery.Lithium cell core, which is crossed, is charged to voltage higher than after 4.2V, starting to generate side effect.Overcharged voltage is higher, danger
It is dangerous also and then higher.After lithium cell voltage is higher than 4.2V, remaining lithium atom quantity is less than half in positive electrode, at this time
Memory location can often collapse, and battery capacity is allowed to generate permanent decline.If continuing to charge, since the memory location of cathode has filled
Lithium atom is expired, subsequent lithium metal can be piled up in negative electrode material surface.These lithium atoms can by negative terminal surface toward lithium ion Lai
Direction grow ingotism.The crystallization of these lithium metals can keep positive and negative anodes short-circuit across diaphragm paper.Sometimes before short circuit occurs
Battery just first explodes, this is because in the process that overcharges, the materials such as electrolyte can crack generation gas, so that battery case or pressure
The rupture of valve blow-up, allows oxygen to enter to react with the lithium atom for being deposited in negative terminal surface, and then explodes.It is accordingly used in conductive lithium electricity
The negative pole structure in pond is extremely important, and structure is concerning the performance for arriving lithium battery.
