The direction that son comes grows ingotism.The crystallization of these lithium metals can make positive and negative anodes short-circuit across diaphragm paper.Sometimes it is sent out in short circuit
Battery just first explodes before death, this is because in the process that overcharges, the materials such as electrolyte can crack generation gas so that battery case or
Pressure valve blow-up ruptures, and oxygen is allowed to enter to react with being deposited in the lithium atom of negative terminal surface, and then explodes.
The widest region of lithium battery applications is mobile communication facility at present, and mobile communication facility uses low capacity
Lithium battery, therefore big safety accident will not be caused, now with electric vehicle development people more and more by lithium battery
Applied to field of automotive power, way is that the lithium battery of various low capacities, low-voltage is formed large capacity height in parallel or series
The battery pack of capacity.Since lithium battery can all distribute heat during being charged and discharged, then heat must be discharged and controlled
In a certain range, on fire or explosion otherwise will be generated, therefore the producer of each lithium battery assembling production is to lithium battery group
Safeguard procedures are studied always.
