| 英文摘要 | Manganese-based layer-structured transition metal oxides are considered promising cathode materials for future sodium batteries owing to their high energy density potential and industrial feasibility. The grain-related anisotropy and electrode/electrolyte side reactions, however, constrain their energy density and cycling lifespan, particularly at high voltages. Large-sized single-crystal O3-typed Na[Ni0.3Mn0.5Cu0.1Ti0.1]O2 was thus designed and successfully synthesized toward high-voltage and long-lifespan sodium batteries. The grain-boundary-free single-crystal structure and unidirectional Na+ diffusion channels enable a faster Na+ diffusion rate and high electronic conductivity. Meanwhile, the large-area exposed (003) crystal plane can not only exhibit a higher energy barrier for electrode-electrolyte side reactions but also alleviate the interlayer sliding and structural collapse during charge-discharge processes. The lattice oxygen in contact with the electrolyte was stabilized, and the TMO6 octahedral structure integrity was maintained as well. A high specific capacity of 160.1 mAh g-1 at a current density of 0.1 C was demonstrated. Coupled with hard carbon as the anode, the full cell can also demonstrate an excellent capacity and cycling stability, achieving a high specific capacity of 141.1 mAh g-1 at 0.1 C. After 100 cycles at 2 C, the capacity retention rate is 97.3%. |
