SOME PERFORMANCE-CHARACTERISTICS OF A SOLID-STATE BATTERY COMPOSED OF CHEVREL PHASE, A COPPER-ION CONDUCTOR, AND PRUSSIAN BLUE

A solid-state battery composed of copper molybdenum sulphide (Chevrel phase: CP), copper-ion conductive solid electrolyte, and iron hexacyanoferrate complex (Prussian blue: PB), was studied from the viewpoint- of its applicability to a recyclable energy source. The electromotive force increased with the copper content of the CP. The discharge capacity increased with increasing sulphur content as well as copper content of the CP. The discharge-charge cycling behaviour indicated that both CP and PB containing a three-dimensional open structure were potential electrode materials for a promising rechargeable battery.
