Lithium-ion batteries(LIBs) currently occupy an important position in the energy storage market, and the development of advanced LIBs with higher energy density and power density, better cycle life and safety is a hot topic for both academia and industry. In recent years, high-entropy materials(heMs) with complex stoichiometric ratios have attracted great attention in the field of LIBs due to their various promising functional properties. The adjustability and synergistic effects of multiple elements in heMs make them possible to break through the bottleneck of traditional electrode materials and electrolytes, providing new opportunities for the development of high-performance LIBs. This article provides an overview of the opportunities and challenges of heMs in LIBs, including cathodes, anodes and electrolytes. The progress of heMs in LIBs is first summarized and analyzed, then the potential advantages and limitations of heMs used in LIBs are concluded, finally some envisioned solutions are proposed to develop more advanced LIBs through heMs.
