The electrochemical lithium storage performance of accordion-like Nb2C MXene in LiPF6 organic electrolyte. The charge-discharge capacity at 0.5 mV s-1 is as high as 738 C g-1 (205 mAh g-1), and it has 2.8 V (0.2 to 3 V) vs. Li+/Li) The large voltage window is currently the best pseudocapacitor lithium storage performance of Nb2C MXene in organic electrolyte. The MXene has excellent cycle stability. After 2400 cycles, the capacity retention rate reaches 90%. The above electrochemical test shows that the MXene electrode material prepared by the Lewis acid molten salt stripping strategy can achieve high capacity, high rate charge and discharge (< 1 min) and large potential window (0.2–3V versus Li+/Li without subsequent single-piece stripping). ) Excellent performance, which paved the way for the practical application of MXene in electrochemical energy storage systems (batteries and lithium ion capacitors).
