📄 Abstract（原文）
As society transitions toward a more sustainable energy future, the demand for low-cost energy storage systems for large-scale applications continues to grow. Classical lithium (Li) layered transition metal oxides have shown great promise and remain the most widely used cathode materials for conventional Li-ion batteries. However, these materials heavily rely on critical elements, including cobalt (Co) and nickel (Ni), to stabilize their ordered layered structure and maintain functionality. Disordered rock salt (so-called DRX) oxides and oxyfluorides have been proposed as sustainable solutions because they offer high specific energy (Wh/kg) and energy density (Wh/L) without using critical elements. In this presentation, I will discuss recent progress in DRX cathode development from materials discovery to practical feasibility. In particular, this presentation will discuss two important topics: (i) the development of highly fluorinated DRX compounds for improved cycling stability and (ii) the development of high-loading DRX cathodes.
