【摘要】 二甲苯作为耐过充添加剂加入锂离子电池电解液中,实验发现,当电压为4.5V(相对于Li/Li+)时,二甲苯开始在正极发生反应,并扩散在正极与隔膜之间。生成的物质阻止了Li+的传递,从而实现了过充电保护。更多还原

【Abstract】 Xylene as overcharging additive was added into Li-ion battery electrolyte.Xylene can electrochemically react at cathode from 4.5V(vs.Li/Li+)and diffuse between cathode and separator.The productor of polymer prevented the ion from transfering,therefore overcharge protection in lithium ion batteries can be achieved.更多还原
