Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 2566 papers online from Feb. 1, 2021 to Mar. 31, 2021. 100 of them were selected to be highlighted. Studies on layered-oxide cathode material foucus on doping, surface coating, preparation of precursors and structural evolution with cycling, among which, investigation on high-nickel ternary layered oxides attracts large attention. Volume expansion and subsequent problems is the focus of silicon-based anode materials, and research is mainly on coating of silicon particles, fabricating composite silicon-based anodes and microstructure control. Other anodes such as lithium metal, graphite and oxide electrode are also involved. Among them, researchs on the interface of lithium and design of three-dimensional structure anode are the main topic. As for solid state electrolytes, investigations mainly include the synthesis, doping and analyses of sulfide, oxide and polymer-oxide composite solid electrolyte. In terms of liquid electrolyte, electrolytes and additives for high-voltage ternary layered oxide cathodes and metal lithium anodes, regulation for positive/negative interface layers, and the performance improvement of graphite and silicon anodes is developed. For solid-state batteries, the preparation and design of composite positive electrodes, surface modification of active materials, and lithium metal/solid electrolyte interface are the main contents. To suppress the “shuttle effect” of Li-S battery, composite sulfur cathode based on catalysis, high ion/electronic conductive matrix, and other battery technologies are developed. The characterization analysis part covers lithium metal deposition, the volume expansion of graphite and silicon anodes, microstructure, dissolved transition metal elements and gas generation of cathode. Degraded interface contact in solid-state batteries, the deposition and peeling of lithium anodes, and the stability of the electrode interface is involved in theoretical simulation work part. The interface related studies involve SEI and the visual characterization in solid-state and liquid batteries mainly.
