Disordered materials for high-performance lithium-ion batteries: A review

Disordered materials (DMs) have become promising materials in the advancement of lithium-ion batteries (LIBs). Their disordered, open structure is conductive to facilitate efficiency lithium-ion storage. DMs with tunable compositions also possess abundant defects that can interact with Li+, further enhancing their electrochemical performances in LIBs. Yet, revealing the structural origin of the superior electrochemical properties of DM-based LIBs remains a challenge. In this article, we review recent advances in the development of DM-based components for LIBs, such as anodes, cathodes, coating layers, and solid-state electrolytes. We give an overview on the primary methods utilized in preparing and characterizing DMs, while also describing the mechanisms involved in DM synthesis. This review article also addresses the correlation between the structural properties of DMs and their electrochemical performances. Moreover, we elucidate the challenges and future perspectives in the advancement of DM-based LIBs. We outline the key advantages of DMs in enhancing LIB performance over their crystalline counterparts, providing insights for developing superior LIBs through tailored DM development.
