Abstract
This invention relates to a novel anode for use in batteries, and to batteries containing the anode, which anode comprises a mixture of a conjugated backbone polymer and another electroactive material selected from the group consisting of metals which alloy with alkali metals and alkali metal cation inserting materials as for example transition metal chalcogenides.
Claims39
A battery comprising:
- (a) an anode comprising as the anode active material one or more conjugated backbone polymers and one or more electroactive materials selected from the group consisting of metals which alloy with alkali metals and alkali metal cation inserting materials;
- (b) an electrolyte comprising an organic solvent and an alkali-metal salt, and
- (c) a cathode;
- said alkali-metal cations from said electrolyte being inserted into said anode as a metal alloy or as an inserted ion in said alkali metal cation inserting material during the charging of said battery.
