Abstract:

This bimonthly review paper highlights 100 recently published papers on lithium batteries. The 100 papers were selected among 3412 online publications in the Web of Science archive from Dec. 1 of 2019 to Jan. 31 of 2020. The failure mechanisms and effects of surface modifications on layered oxides, especially Ni-rich (or even Ni-only) cathode materials, are being extensively investigated. Li-rich and high voltage LiCoO2-layered cathode materials are also studied, although less frequently than layered oxides. Among the anode materials, Si-based composites are thought to improve the cycling performance and columbic efficiency by inhibiting the volume expansion without losing their electron conductivity. Meanwhile, the cycling properties of metallic lithium anodes have been improved by applying various surface-covering layers, electrolyte additives, and current collector modifications. Solid state electrolytes (both inorganic and organic) and their compositions are intensively researched, and new additives and lithium salts have been proposed as liquid electrolytes. Solid state Li-S and Li-O2 batteries remain in the early stage of development, but new electrode preparation methods that maintain the conducting network and reaction reversibility have been proposed. The dynamic changes in morphology, lithium, and potential distribution have been observed by various in situ technologies. The mechanism of SEI has been theoretically analyzed, and the mechanical and thermal properties of solid-state batteries have been explored in mesoscopic and macroscopic models.
