Owing to the advantages of low cost, rich resources, and intrinsic safety, aqueous Zn-ion batteries have attracted broad attention as promising energy storage technology for large-scale smart grids. The cathodes developed rapidly, including Mn-based cathodes, V-based halogen cathodes. High specific capacity long cycling lifespan been achieved. However, when mass loading cathode materials is scaled up practical level, stability rate property are very unsatisfactory. Therefore, in this review, we deeply analyze key issues that limit electrochemical performance high-loading batteries. Subsequently, comprehensively summarize effective solutions above issues, (1) rational binder design, (2) three-dimensional (3) material structural optimization, (4) interface engineering Zn anodes. Finally, give a critical perspective from commercial application future development high-energy-density

Abstract Cu anodes exhibit a higher theoretical specific capacity (843 mAh g −1 or 7558 cm −3 ) than Zn (820 5855 ), and have garnered widespread attention. However, aqueous Cu‐ion batteries suffer from severe dendrite growth, limited cycle life, poor high‐temperature performance. To the best of our knowledge, this is first time that deep eutectic solvent (DES) electrolyte proposed to address these issues. Fourier transform infrared spectroscopy molecular dynamics simulations confirm DES coordinates with 2+ , thereby modulating deposition behavior. Consequently, planar extended life (6000 h versus 730 h) are achieved. Furthermore, exhibits promising application potential under harsh conditions. A Cu─MnO 2 full cell retains 174.8 after 300 cycles at 50 °C.
