Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 4209 papers online from Aug. 1, 2021 to Sep. 30, 2021. 100 of them were selected to be highlighted. High-nickel ternary layered, high-voltage LCO layered and Li-rich Mn-rich layered cathode materials are still under extensive investigations of the influences of doping and interface modifications on their electrochemical performances and surface and bulk evolution of structures under prolong cycling. The researches of lithium metal anode mainly focus on the surface modification and alternation of direction of lithium deposition. Large efforts have been devoted to solid state electrolytes including sulfide and oxide solid electrolyte, polymer solid electrolyte and composite solid-state electrolytes. The research works on liquid electrolytes involves mainly matching various electrolytes and solvents with battery materials, and searching for new additives. For solid-state batteries, the studies mainly focus on interface and for lithium-sulfur batteries, the works are mainly on improving the activity of sulfur and mitigating the shuttling effect. The focuses of characterization techniques are on bulk structure of materials and electrode-electrolyte interface and the hot topics are characterization interfaces of solid-state batteries. Furthermore, there are theoretical works for the surface oxygen activity of materials, interface structures, lithium transportation mechanisms, with interface structures concerning SEI formation. There are also some papers on modification of current collectors and pre-lithiation of electrodes.

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