Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 3015 papers online from Apr. 1, 2021 to May 31, 2021. 100 of them were selected to be highlighted. Nickel rich ternary layered oxides and the high-voltage spinel materials are still under extensive investigations for the influences of preparation of precursors, doping and interface modifications on their electrochemical performances. The researches of silicon-based composite anode materials focus mainly on the design of electrode structure, while the researches of lithium metal anode focus on electrolyte additives and further to regulate the growth of SEI and inhibit the formation of lithium dendrites. Solid state electrolytes including oxide, sulfide, polymer and composite materials have been studied. Meanwhile, large efforts are still devoted to liquid electrolytes for the additives to improve the performances of graphite and silicon anodes, the high-voltage spinel and LiCoO2 and ternary layered structure cathode materials. For solid-state batteries, the design and preparation of composite cathode, surface modification of active materials, and lithium metal/solid electrolyte interface are the main topics. To suppress the "shuttle effect" of Li-S battery, composite sulfur cathode with high ion/electronic conductive matrix and electrolyte additives are studied. The characterization work include the investigations on Li deposition, SEI of Si-based anode, microstructures and interfacial reaction of composite cathodes. Furthermore, there are a few theoretical calculation papers related to the stability of solid electrolyte, the interfaces of solid state electrolyte/Li and Li metal deposition.
