Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 3295 papers online from Feb. 01, 2020 to Mar. 31, 2020. 100 of them were selected to be highlighted. Layered oxide especially Ni-rich cathode materials are under extensive investigations for studying the failure mechanism and the effects of surface modifications. There are also a few papers on Li-rich and high voltage LiCoO2 materials. As for anode materials, large efforts were devoted to Si based composite anode materials to improving the cycling performance and columbic efficiency by inhibiting the volume expansion and keeping the electron conductivity. Cycling properties of metallic lithium anode are improved by using different kinds of surface cover layer, electrolyte additives and current collector modifications. Both of inorganic and polymer based solid state electrolyte are burningly researched and new additives and lithium salts are used for liquid electrolyte. Solid state batteries, Li-S and Li-O2 batteries are still at early stage and new electrode preparation methods are proposed to keep the conducting network and reaction reversibility. Various in-situ technologies are used to observe dynamic changes of morphology, lithium and potential distribution. Theoretical works are related to the mechanism of SEI formation, and some mesoscopic and macroscopic models for kinetic properties.

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