摘要：

Rechargeable flexible zinc-air batteries (FZABs) are promising alternatives to lithium-ion batteries for portable and wearable devices. A critical component of FZABs is the gel polymer electrolyte (GPE), which faces challenges such as water loss and poor tensile flexibility under extreme conditions. These issues must be addressed to ensure high utilization of the Zn anode and air catalyst and to meet the demands of harsh environments. This study presents a dual-network GPE leveraging the physical crosslinking between polyacrylic acid (PAA) and kappa-carrageenan (KC) for FZABs. The polar -COO- ...
