摘要

采用成分调控策略制备了一种双相Na5V3(PO4)2(P2O7)2/C复合材料，作为可充电钠离子电池的超快阴极。它在1000 mA g-1的大电流下实现了82.4 mA h g-1的高实用容量，并在1500次循环后获得了88%的令人印象深刻的容量保持率。

Ultrafast biphasic Na5V3(PO4)2(P2O7)2/C composite cathode for sodium-ion batteries†

A biphasic Na₅V₃(PO₄)₂(P₂O₇)₂/C composite is developed via a composition-regulation strategy as an ultrafast cathode for rechargeable sodium-ion batteries. It achieves a high practical capacity of 82.4 mA h g⁻¹ at the large current of 1000 mA g⁻¹ and obtains an impressive capacity retention of 88% after 1500 cycles.
