Abstract
The fast emerging field of multivalent (MV) battery systems offers promising methods for addressing safety, energy density, cost, and manufacturing issues concerning currently available Li-ion battery technology, particularly in the application of large-scale energy storage devices. Although some obstacles still remain, remarkable progress has been made toward developing electrode materials for the MV systems. This paper focuses on showcasing the significant breakthroughs achieved in nonaqueous Ca-ion and Al-ion battery technologies, specifically, in terms of the advancements concerning their positive electrodes in the past three years. The crucial role of computation and machine learning techniques for the customization of existing materials and the discovery of new materials for MV battery applications are highlighted. Finally, recommendations for further MV battery related research and development are provided.
