摘　　要：Alkali metal batteries(AMBs)have undergone substantial development in portable devices due to their high energy density and durable cycle performance.However,with the rising demand for smart wearable electronic devices,a growing focus on safety and durability becomes increasingly apparent.An effective strategy to address these increased requirements involves employing the quasi-solid gel electrolytes(QSGEs).This review focuses on the application of QSGEs in AMBs,emphasizing four types of gel electrolytes and their influence on battery performance and stability.First,self-healing gels are discussed to prolong battery life and enhance safety through self-repair mechanisms.Then,flexible gels are explored for their mechanical flexibility,making them suitable for wearable devices and flexible electronics.In addition,biomimetic gels inspired by natural designs are introduced for high-performance AMBs.Furthermore,biomass materials gels are presented,derived from natural biomaterials,offering environmental friendliness and biocompatibility.Finally,the perspectives and challenges for future developments are discussed in terms of enhancing the ionic conductivity,mechanical strength,and environmental stability of novel gel materials.The review underscores the significant contributions of these QSGEs in enhancing AMBs performance,including increased lifespan,safety,and adaptability,providing new insights and directions for future research and applications in the field.
