【摘要】 二甲苯作为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,二甲苯发生电聚合反应。生成的导电聚合物膜使电池内部形成短路而发生自放电,可把电池电压控制在4.5V,从而使电池处于更安全的充电状态。更多还原

【Abstract】 Xylene as overcharging additive was added into Li-ion battery electrolyte.Xylene could be electrochemically polymerized at 4.5 V.The productor of polymerization resulted in short-circuit and caused self-discharge,the cell’s potential can be controlled around 4.5 V,and the Li-ion batteries can be much safer when overcharged.更多还原
