Fig. 4: Capacitive contribution of Ti2CTx MXene and TiNbCTx MXene.
From: TiNbC MXene cathode for high-performance aluminum-ion batteries
a CV curves of Ti2CTx MXene at different scan rates from 0.3 to 5 mV s−1. b Contribution of capacitive behavior changes as the scan rate increases. c Self-discharge curve of the Ti2CTx MXene cathode at a charge rate of 200 mA g−1. d CV curves of TiNbCTx MXene at different scan rates from 0.3 to 10 mV s−1. e Contribution of capacitive behavior changes as the scan rate increases. f Self-discharge curve of the TiNbCTx MXene cathode at a charge rate of 200 mA g−1.
