摘要: The modern technology needs the electrochemical energy devices with increased safety, larger power and densities in addition to long cycle lifetime. solid state electrolytes (SSE) have been developed due dramatic development of portable consumer electronics increasing concerns on flexibility energy-storage as well elimination some drawbacks liquid electrolytes. This review introduces all types SSEs for various including batteries, fuel cells, solar cells supercapacitors (SCs) an emphasis SCs. is followed by presentation new containing redox agents, nano metal oxides carbon materials along other fillers. Herein, we show that use novel could contribute greatly enhance performance related improved specific capacitances, densities.
