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 electrode/electrolyte side reactions, however, constrain cycling lifespan, particularly at voltages. Large-sized single-crystal O3-typed Na[Ni0.3Mn0.5Cu0.1Ti0.1]O2 was thus designed successfully synthesized toward high-voltage long-lifespan batteries. grain-boundary-free structure unidirectional Na+ diffusion channels enable a faster rate electronic conductivity. Meanwhile, the large-area exposed (003) crystal plane can not only exhibit higher barrier electrode–electrolyte reactions but also alleviate interlayer sliding structural collapse during charge–discharge processes. lattice oxygen in contact with electrolyte stabilized, TMO6 octahedral integrity maintained as well. A specific capacity of 160.1 mAh g–1 current 0.1 C demonstrated. Coupled hard carbon anode, full cell demonstrate an excellent stability, achieving 141.1 C. After 100 cycles 2 C, retention is 97.3%.
