Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 2731 papers online from Oct. 1, 2020 to Nov. 30, 2020. 100 of them were selected to be highlighted. Ni-rich layered oxides and Li-rich oxide cathode materials with oxygen redox reaction drawed large attentions. Doping and coating are used to improve the performances of mateials. The swelling of cell using Si-based anode material is investigated. The methods for improving the cycling peroperties of Si-based anode include using new binders, to form artificial SEI, etc. Carbon coated Ti2Nb10O29, grapheneand its commposites and 3D porous carbon anode materials are also reported. Electrolyte with additives are developped for high voltage cathode matreials including Ni-rich oxides, Li-rich oxides, and spinel Ni-Mn oxides, also for Li-S and thickelectrode cells. Sullfide based solid state elelctrolyte and its composite with polymer are studied. Enhanced conductivity is obtianed for Si doped Li6PS5I and B doped Li7La3Zr2O12.There are few papers related to solid state battery, LI-S battery and Lithium oxygen battery.Analysis work focuses on interface SEI, Lithium deposition/striping in solid state cell, Li distributuon in electode, gasing of the cell, etc. Theoretical simulations cover the interface SEI formation mechanism, kinetics of thick electrodes, etc.

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