A self-healing ionogel-based zinc-air battery (ZAB) with wide-temperature flexibility and ultra-long cycling life has been developed. The ionogel, named PAM-PEGMA-IL, is synthesized through photopolymerization of acrylamide and poly(ethylene glycol) monomethyl ether acrylate in 1-ethyl-3-methylimidazolium dicyanamide with zinc acetate dihydrate. This ionogel exhibits high ionic conductivity, good mechanical strength, and self-healing properties due to reversible hydrogen bonding. It can operate over a wide temperature range (-75 to 65°C) and maintains stability under harsh conditions. The self-healing ZABs, named SWF-ZABs, can recover their performance after damage, offering long-term reliability. The SWF-ZABs demonstrate exceptional cycling stability, with cycle lives of 400, 340, and 275 hours at -20, 25, and 40°C, respectively. They also maintain performance after storage at extreme temperatures and in vacuum. The SWF-ZABs are applied in wearable devices, such as digital watches and patch thermometers, functioning reliably across a wide temperature range. The self-healing capability of the ionogel enables repeated recovery of battery performance, enhancing the reliability and service life of the ZABs. This study presents a promising approach for developing electrolytes for flexible zinc-air batteries with wide operating temperature ranges and long cycling lives.A self-healing ionogel-based zinc-air battery (ZAB) with wide-temperature flexibility and ultra-long cycling life has been developed.
