High power and good stability enable supercapacitors to work efficiently at high temperatures. However, the high-temperature-induced excessive ion transfer of the electrolyte would lead to severe self-discharge behavior, which has often been overlooked but can be highly detrimental. In this study, solid electrolytes consisting of poly(ethylene oxide) (PEO), bentonite clay, and ionic liquids (IL)-PEO-clay@[EMIM][BF4 ] (PCE), PEO-clay@[BMIM][BF4 ] (PC, and PEO-clay@[HMIM][BF4 ] (PCH) lead to dramatic decreases in self-discharge when used in all-solid-state
