Abstract:

This bimonthly review provides a comprehensive overview of the recent research on lithium batteries. A total of 6113 online papers, published between June 1, 2024 and July 31, 2024, were examined using the Web of Science database. The BERTopic topic model was employed to analyze abstracts and map research topics related to lithium batteries. From these, 100 papers were selected for detailed review to cover various aspects of lithium battery development. Cathode materials such as LiNi0.5Mn1.5O4 and lithium-rich oxides have been enhanced by doping, surface coating, and microstructural modification. The cycling performance of silicon-based anodes has improved through structural design innovations. Great efforts have focused on the interface design of lithium metal anodes. Studies on solid-state electrolytes have focused on the structural design and performance of polymer- and halide-based systems. Conversely, liquid electrolytes have seen improvements through the optimization of solvents and lithium salts for different battery applications, along with the incorporation of novel functional additives. In the context of solid-state batteries, extensive investigations have been conducted on the modification, surface coating, cathode synthesis methods, interface construction, three-dimensional structural design of lithium metal anodes, and the use of multilayer electrolytes. The structural design of cathodes and liquid electrolytes for lithium-sulfur batteries has proven beneficial in extending their cycling life. In addition, there are a few studies related to dry electrode technology, binders, and separators for cells. New current collectors and electrolytes have been explored for lithium-oxygen batteries. Moreover, numerous studies address ion transport and degradation mechanisms in electrodes, lithium deposition morphology, and solid-electrolyte interphase structural evolution in electrolytes. Other topics include thermal runaway analysis in full batteries, theoretical simulations of solvent effects on cathode-electrolyte interphase components, and efforts to reduce battery costs and optimize manufacturing processes.
