In response to societal developments and the growing demand for high-energy-density battery systems, alkali metal batteries (AMBs) have emerged as promising candidates next-generation energy storage. Despite their high theoretical specific capacity output voltage, AMBs face critical challenges related reactivity with electrolytes unstable interphases. This review, from perspective of electrolytes, analyzes AMB failure mechanisms, including interfacial side reactions, active materials loss, dendrite growth. It then reviews recent advances in innovative electrolyte molecular designs, such ether, ester, sulfone, sulfonamide, phosphate, salt, aimed at overcoming above-mentioned challenges. Finally, we propose current design principles future directions that can help precise design.

The structural and interfacial instability of Ni-rich layered cathodes LiNi0.9Co0.05Mn0.05O2 (NCM9055) severely hinders their commercial application. In this work, straightforward high-temperature solid-state methods are utilized to successfully synthesize Nb-doped Li3PO4-coated by combining two niobium sources, NbOPO4·3H2O Nb2O5, for the first time. Studies indicate that Nb doping enhanced integrity structure, Li3PO4 coating reduced water absorption on surface considerably boosted durability interface. dual-modified cathode Li(Ni0.9Co0.05Mn0.05)0.985Nb0.015O2@Li3PO4 (NCM-2) exhibits remarkable cycling rate performance. initial discharge specific capacity NCM-2 is 203.33 mAh g-1 at 0.1 C 196.04 1 C, while retention after 200 cycles 91.38% which much higher than pristine NCM9055 (49.96%). addition, it also provides a superior about 175.63 even 5 C. This study emphasizes feasible approach enhancing stability interfaces bulk structures.

The ongoing advancements in lithium-ion battery technology are pivotal propelling the performance of modern electronic devices and electric vehicles. Amongst various components, cathode material significantly influences performance, such as specific capacity, capacity retention rate performance. Ternary materials, composed nickel, manganese, cobalt (NCM), offer a balanced combination these traits. Recent developments focus on elemental doping, which involves substituting fraction NCM constituent ions with alternative cations aluminum, titanium, or magnesium. This strategic substitution aims to enhance structural stability, increase retention, improve resistance thermal runaway. Doped ternary materials have shown promising results, improvements cycle life operational safety. However, quest for optimal doping elements concentrations persists maximize while minimizing cost environmental impact, ensuring progression towards high-energy-density, durable, safe technologies.
