Abstract
Provided is a novel electrode composition suitable for use in an electrochemical cell. The composition includes a polymeric binder material and a doped tungsten (IV) oxide active material. The active material includes a tungsten (IV) oxide host material and a metal dopant in the host material effective to increase the charge-discharge capacity per unit weight of the active material when used in an electrochemical cell. Also provided is a method for forming the electrode composition and an electrochemical cell comprising the composition. The invention results in an electrochemical cell having improved charge-discharge capacity per unit weight of the electrode active material, and is additionally chemically and electrochemically stable.
