Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 3128 papers online from Feb. 1, 2022 to Mar. 31, 2022. 100 of them were selected to be highlighted. High-nickel ternary layered oxides, LiNiO2,LiCoO2 and Li-rich oxides as cathode materials are still under extensive investigations for surface coating, preparation of precursors and structural evolution with cycling. The methods for improving the cycling performances of Si-based anode focus on surface coating and 3D structure design of the composite Si/C and Si/Sn anodes. Metallic lithium anode is extensively studied and 3D structure design and surface reconstruction are common methods. Solid state electrolyte including oxide, sulfide and composite materials have been widely studied. Meanwhile, large efforts are still devoted to liquid electrolytes for the optimizing the electrolyte for Li or graphite anode, and the high-voltage cathode materials. For solid-state batteries, there are a few papers related to the design of composite cathode, bi-layer electrolyte, and inhibition of Li dendrite and side reactions. Other relevant works are also presented to cathode design of liquid lithium sulfur battery. The characterization techniques are focused on lithium diffusion, SEI formation, electrochemical and chemical stability of the sulfide electrolytes. Theoretical simulations are directed to the doping of ternary oxide cathode materials, physical and chemical properties of liquid electrolyte and screening of solid electrolytes. The interfaces of liquid electrolyte/electrodes and solid state electrolyte/Li are also drawn large attentions.

Key words: lithium batteries, cathode material, anode material, solid state electrolyte, battery technology
