High-entropy battery materials (HEBMs) have emerged as a promising frontier in energy storage and conversion, garnering significant global research interest. These materials are characterized by their unique structural properties, compositional complexity, entropy-driven stabilization, superionic conductivity, and low activation energy.
On the basis of design principles, the intrinsic high theoretical capacities are attributed to their excellent host chemistry that stores more energy. However, the concomitant large volume variation, low conductivity, voltage hysteresis, and instability of the SEI film are major problems for further practical applications in batteries.
In electrochemical energy storage, multi–component designs have significantly enhanced battery materials performances by various means. Such as, increase of carrier ions (Li +, Na +, K +) energy in solid–state electrolytes (SSEs) , and decrease in ion–solvation strength to improve mobility in LEs , .
This review presents a new insight by summarizing the advances in structure and property optimizations of battery electrode materials for high-efficiency energy storage. In-depth understanding, efficient optimization strategies, and advanced techniques on electrode materials are also highlighted.
Choice and Types of Materials for Main Components Materials themselves are the most fundamental design factors that determine the electrochemical potential window, reaction chemistry (including reaction kinetics and mechanisms), and the types of batteries (e.g., aqueous, non-aqueous, polymeric, or solid-state).
In-depth understanding, efficient optimization strategies, and advanced techniques on electrode materials are also highlighted. By now, many challenges still exist for achieving great breakthroughs in high-performance scalable batteries.
