the Chemical principal of Li-battery Now recognizes is the rocking chair theory The lithium ion comes in and goes out in the layered material crystal,which has the energy changed. In the normal sufficient electric discharge situation,the lithium ion passes in and out only directs the spacing change,but cannot cause the crystal structure change PDF文件使用"pdfFactory Pro”试用版本创建幽fineprint.com,cn

The causes of the explosion According to the rocking chair theory,in the electrically charged condition graphite (石墨)cathode meets the spontaneous combustion This indicated the battery when it has flowed can have the detonation When flowed forms of the lithium atom's speed is quicker,it can create the lithium atom to pile up,cause the battery too short-circuit,and emit the massive quantity of heats.

This causes the electrolyte decomposition to produce the massive gas,the intrinsic pressure suddenly rises creates the battery to explode In addition,the lithium ion battery excessively hot can have the detonation The lithium ion and the electrolyte can response which causes explosion.
