Evaluating the Potential of Thermal Spray and Other Coatings Methods for Li-ion Battery Applications

Li-ion batteries (LIBs) are essential to advancing green energy technologies, particularly for electronic devices, electric vehicles, and energy storage systems for renewable energy. This has driven the demand for high-performance LIBs. High-entropy oxides (HEOs), a novel class of ceramic materials, have emerged as promising candidates for anode, cathode, and solid-state electrolyte materials in LIBs due to their unique phase structure, excellent ionic conductivity and cyclic stability. The study explores the current advancements in thermal spray and other coating methods for LIB applications focusing on both conventional materials and HEOs. Additionally, this study reviews the coatings' properties particularly their electrochemical performance to assess their potential in LIBs. The underlying mechanisms of these materials are also discussed, highlighting their prospects for future LIB applications.
