Summary: In this study, a design scheme for high-energy cathode materials for Li-ion batteries is proposed. By constructing a hierarchical structure with different chemical compositions from the bulk to the surface, the issue of capacity decay and short cycle life in high-voltage cycling of cathode materials is addressed. The introduction of Cr3+ in the inner end suppresses the dissolution of Mn3+ and partial Mn2+ to improve bulk stability. The construction of an undoped shell eliminates the catalytic effect of dopants on interfacial side reactions, enhancing interfacial stability.

Summary: Due to its higher energy density, high thermal stability, and low cost, the spinel LiNi0.5Mn1.5O4 (LNMO) has great potential as a cathode material for lithium-ion batteries. However, the interfacial and bulk reactions in LNMO can lead to capacity decay. In this study, a Ge-doping strategy is proposed to regulate the ratio of ordered/disordered phases in LNMO, resulting in exceptional structural stability and improved cycling performance. The incorporation of Ge into LNMO increases the amount of Mn4+ and blocks the diffusion of transition metal ions, preventing capacity deterioration during cycling.

Summary: In this study, the addition of CMC electrolyte additive in AZICs successfully addresses the performance issues caused by zinc deposition and parasitic reactions. The CMC additive can adsorb onto the (101) facet of zinc, preventing the formation of zinc dendrites. Moreover, the interaction of CMC with Zn2+ alters the solvation structure and suppresses water-induced side reactions. This strategy significantly improves the cyclic stability of the zinc anode at both low and high rates, thus promoting the comprehensive performance of AZICs.
