Cyclablhty

features of an all sohd-state hthmm polyblthlophene battery with PEO,,-LlCIO, polymer electrolyte was mvestlgated at 70°C working temperature

Although the capacity values of the sohd device are lower than those of the comparable one with hqmd electrolyte, the cyclablhty performances are promtsmg and the cycle hfe IS satisfactory

The shelf-hfe of the sohd battery was also mvestlgated The self-dtscharge rate IS fast at 70°C but IS not appreciable at room temperature
