Abstract
- An all-solid-state battery was fabricated by using a PEO-base solid polymer as electrolyte and an organic material anthraquinone (AQ) as cathode. The anthraquinone delivers a specific discharge capacity of 183 mAh g − 1 at first cycle at current density of 20 mA g − 1 at 65 °C. The use of solid polymer electrolyte reduces the dissolution of organic active material greatly, improving the cycle performance of the battery. Therefore, the all-solid-state battery delivers a better cycling property. It can still retain a capacity of 136 mAh g − 1 after 50 cycles, corresponding to a capacity retention of 74%, while capacity retention of the cell using liquid electrolyte was only 28% after 20 cycles. The all-solid-state battery shows more stable interfacial resistance during charge–discharge process. It displays good rate ability and a better thermal stability. [ABSTRACT FROM AUTHOR]
