A novel battery construction which incorporates a disconnect safety device which is hydraulically activated by an increase in solid volume upon abusive overcharge of the battery to disconnect the cathode or anode. A rechargeable battery which comprises: (a) a LixMO2 cathode wherein x, is equal to or less than 1.1, and M is Ni, Co, Mn or combinations thereof; (b) a carbonaceous anode; (c) an electrolyte of one or more lithium salts dissolved in one or more non-aqueous organic solvents; and (d) an internal disconnect device which activates by hydraulic means on overcharge. |
