2. A non-aqueous rechargeable lithium battery as claimed in claim 1 wherein the monomer additive comprises less than about 5% by volume of the mixture of liquid electrolyte and monomer.
3. A non-aqueous rechargeable lithium ion battery having a maximum operating charging voltage and overcharge protection comprising:
- a lithium insertion compound cathode;
- a lithium insertion compound anode;
- a separator;
- a non-aqueous liquid electrolyte incapable of polymerizing at voltages greater than the maximum operating voltage of the lithium ion battery such that the battery is protected during overcharge abuse; and
- an aromatic additive mixed in said liquid electrolyte, said additive polymerizing at battery voltages greater than the maximum operating voltage thereby increasing the internal resistance of the lithium ion battery and protecting the battery during overcharge abuse.
