This invention discloses a secondary cell using a polymeric material comprising:
(a) a positive electrode (1) containing a polymer having conjugated double bonds capable of forming electrochemically reversible charge-transfer complexes with negative ions in an electrolyte, (b) a negative electrode (2) containing carbon having a graphite ring capable of forming electrochemically reversible interlaminar compounds with positive ions in said electrolyte, and (c) an electrolyte solution (5) interposed between said positive electrode (1) and said negative electrode (2).
摘要:
A secondary cell comprises opposed positive and negative electrodes of polymers, each having conjugated double bonds, such as polyacetylene, poly-phenylene, polythienylene and polypyrrole, and an electrolyte solution comprising an electrolyte dissolved in a nitrile compound and being interposed between the two electrodes.
摘要:
A secondary battery having at least one electrode made from a polymer having conjugated double bonds in a main chain such as polyacetylene can be improved remarkably in charge-discharge cycle life by making the electrode surface area of the negative electrode larger than that of the positive electrode.
