Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 3193 papers online from Dec 1, 2020 to Jan 31, 2021. 100 of them were selected to be highlighted. High-nickel ternary layered and Li-rich oxide cathode materials are still under extensive investigations for surface coating, preparation of precursors and structural evolution with cycling. The methods for improving the cycling properties of Si-based anode focus on coating Si particles and 3D structure design of the composite Si/C and Si/Cu anodes, while 3D structure design and surface reconstruction are used for metallic lithium anode. Solid state electrolyte including oxide, sulfide and composite materials have been studied. Meanwhile, large efforts are still devoted to liquid electrolytes for the optimizing the electrolyte for graphite anode, the high-voltage spinel and LiCoO2, ternary layered, and Li-rich oxide cathode materials. For solid-state batteries, there are a few papers related to the design of composite cathode, bi-layer electrolyte, and modification of Li metal anodes. Other relevant works are also presented to the 3D structure design of S-based cathodes and the effects of electron-conductive additives in to electrodes. The characterization techniques are focused on Li deposition, swelling of Si-based anode, micostructures of cathodes and gassing of cells. Theoretical simulations is mainly on the formation mechanism of SEI and kinetics of thick electrodes. The interfaces of layered cathode and solid/liquid electrolyte, liquid electrolyte/anode, and solid state electrolyte/Li are also widely studied.
