Abstract:
Over recent decades, rapid advancements in energy technology have transformed human life. Lithium‐ion batteries (LIBs) have played a pivotal role nevertheless concerns about limited lithium resources and price fluctuations underscore the need for sustainability. Sodium‐ion batteries (SIBs), operating on principles akin to LIBs, have emerged as promising candidates for rechargeable batteries in the next generation of energy storage systems, primarily due to their cost‐effectiveness and sustainable attributes. Analogous to LIBs, the cathode in SIBs assumes a critical role in dictating the electr

AbstractAlthough O3‐type layered oxides are promising candidates as cathode materials in sodium‐ion batteries (SIBs), it is still plagued by poor stabilities owing to the inevitable degradation of Na‐O bond and subsequent side reactions as exposed to moist atmosphere. Here, a new O3‐type high‐entropy layered oxide NaMn0.4Fe0.3Ni0.2M0.1O2 (HE‐NaMFN, M = Cu/Ti/Zn/Sn/Sb) is developed by high‐entropy modulation on NaMn0.5Fe0.3Ni0.2O2. This process involves the implantation of five metal atoms with different d ‐orbital electron numbers into the layered oxide, increasing the energy gap between O 2p

Abstract As the analogs of Li-rich materials, Na-rich transition metal layered oxides are promising cathode materials for Na-ion batteries owing to their high theoretical capacity and energy density through cumulative cationic and anionic redox. However, most of the reported Na-rich cathode materials are mainly Ru- and Ir-based layered oxides, which limits the practical application. Herein, we report a Na-rich and Ru-doped O3-type Na1.1Ni0.35Mn0.55O2 cathode to mitigate this issue.
