摘要
Mn-based NASICON (Na super ionic conductor)-typed compounds are potentially applied as cathode materials for Na-ion batteries. However, cycling instability and poor rate capability limits its large-scale application. Herein, Na3+xMnTi1-xVx(PO4)3 with various Ti/V ratios were synthesized. The influence of the Ti/V ratios on the composition, structure and electrochemical properties were investigated. With increasing with content of V, cell parameters a (and b) and cell volume increases. Among these materials, Na3.7MnTi0.3V0.7(PO4)3 exhibits the best cycle stability and rate capability (62.7 mAh/g at 5 C, 53.2 mAh/g at 10 C), demonstrating potential application as cathode material for Na-ion batteries.
