Non-aqueous rechargeable lithium batteries are often equipped with internal electrical disconnect devices to protect against overcharge abuse. At the abnormally high voltages of overcharge, these devices can be activated by gasses generated as a result of the electrochemical polymerization of suitable monomer additives incorporated in the electrolyte. Aromatic compounds such as biphenyl are particularly suitable aromatic additives for LiCoO 2 based lithium ion batteries. |
