This study presents the development of self-healing ionogels for use in flexible zinc-air batteries (ZABs) to address the limitations of hydrogel-based ZABs, such as short service life, narrow operating temperature range, and repair difficulty. The self-healing ionogel, synthesized by photopolymerizing acrylamide and poly(ethylene glycol) monomethyl ether acrylate in 1-ethyl-3-methylimidazolium dicyanamide with zinc acetate dihydrate, exhibits excellent properties including high ionic conductivity, good mechanical strength, and efficient self-healing capabilities. These properties enable the fabrication of self-healing and wide-temperature flexible ZABs with ultra-long cycling lives. The ZABs demonstrate stable performance under harsh conditions and can repeatedly self-heal after damage, making them suitable for powering wearable devices. The study highlights the potential of self-healing ionogels as a promising electrolyte for flexible rechargeable batteries.This study presents the development of self-healing ionogels for use in flexible zinc-air batteries (ZABs) to address the limitations of hydrogel-based ZABs, such as short service life, narrow operating temperature range, and repair difficulty.
