英文摘要 | A sodium-rich vanadium compound, Na4V2O7, is investigated as a cathode material for sodium-ion batteries, which delivers a high reversible capacity of 194 mA h g(-1)after activating to 4.7 V. By limiting the cut-off voltage to 4.4 V, a good capacity retention of 93% after 50 cycles is achieved. The material exhibits a negligible volume variation of 1.04% during Na+(de-)intercalation, demonstrating that Na(4)V(2)O(7)is structurally-stable. |
