This bimonthly review paper highlights 100 recent published papers on lithium batteries.We searched the Web of Science and found 6213 papers online from Dec.1,2023 to Jan.31,2024.100 of them were selected to be highlighted.The selected papers of cathode materials focus on high-nickel ternary layered oxides and Li-rich oxides,and the effects of doping,interface modifications and structural evolution with prolonged cycling are investigated.For anode materials,silicon-based composite materials are improved by surface modification and optimized electrode structure to mitigate the effects of volume changes.Efforts have also been devoted to designing artificial interface and controlling the inhomogeneous plating of lithium metal anode.The relation of structure design and performances of chloride-based,sulfide-based and polymer-based solid-state electrolytes has been extensively studied.Different combination of solvents,lithium salts,and functional additives are used for liquid electrolytes to meet the requirements for battery applications.For solid-state batteries,the modification and surface coating of the cathode,the design of composite cathode,the interface to anode/electrolyte interface and 3D anode have been widely investigated.Studies on lithium-sulfur batteries are mainly focused on the structural design of the cathode and the development of functional coating and electrolytes,and solid state lithium-sulfur battery has also drawn large attentions.New binders and the dry electrode coating technology are developed for Li-ion batteries.There are a few papers for the characterization techniques of structural phase transition of the cathode materials and the interfacial evolution of lithium deposition,while theoretical papers are mainly related to the study of interfacial ion transport and the optimization of electrode structure.
