Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 2739 papers online from Jun. 1, 2021 to Jul. 31, 2021. 100 of them were selected to be highlighted. Layered oxide cathode including Ni-rich oxides, lithium-rich materials, and spinel materials are still under extensive investigations for the modification of doping and coating. Large efforts were devoted to design the three-dimensional electrode structure, surface modification, and plating inhomogeneity of lithium metal anode. For silicon-based anode materials, beside 3D structure design, the researches focused on the development of electrode binders, aiming at buffering the volume change during cycling. The researches of solid-state electrolytes mainly focused on optimizing pre-existing materials and developing new materials, whereas liquid electrolytes mainly focused on the optimal design of solvents and lithium salts for different battery systems and developing new additives. The works of solid-state battery involve mainly the modification of interfaces, and suppressing the "shuttle effect" is the main task for Li-S battery. 3D lithium metal plating and electrode behavior under high current density were characterized by in-situ and ex-situ technologies. Theoretical calculation papers were related to ion transport and some interfacial reaction works were related to the SEI analysis. There are also a few papers related to the investigation of current collectors' modification and pre-lithiation techniques.
