In electrochemical energy storage, high-entropy design has shown advantageous impacts on battery materials such as suppressing undesired short-range order, frustrating energy landscape, decreasing volumetric change and reducing the reliance on critical metals.
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.
The frameworks for computational and inverse design established by MGI have led to the creation of materials with remarkable properties, particularly in the realm of energy materials, contributing significantly to the advancements in High-Energy Battery Materials (HEBMs).
When applied to battery applications, enhancements in tailoring short-range order, energy landscape, volumetric change, and chemical versatility make high-entropy materials particularly valuable. The identified advantages of HEBMs are summarized in Fig. 1. Fig. 1: The unique properties of high-entropy battery materials (HEBMs).
Active electrode materials with high capacities, such as silicon , Li metal anodes , and Li-rich cathodes , have been extensively investigated. Nonflammable and Li dendrite-proof solid-state electrolytes have been paired with Li metal anodes to construct high-energy–density solid-state batteries .
Functional gradient material (FGM) design endows the electrode materials with property gradient, thus providing great opportunities to address the kinetics and stability obstacles. To date, still no review or perspective has covered recent advancements in gradient design at multiple scales for boosting lithium battery performances.
