construction of a vanadium dioxide and MXene heterostructure towards high-capacity ammonium ion storage

A VO 2 @V 2 C (VO@VCM) anode material is prepared for aqueous ammonium ion batteries (AmIBs) by one-step in situ oxidation of a 2D V 2 C MXene. The VO@VCM delivers a high capacity of 226 mA h g −1 , superior rate performance, and long cycling stability due to the synergistic effect of the highly con...

Description
Summary:A VO 2 @V 2 C (VO@VCM) anode material is prepared for aqueous ammonium ion batteries (AmIBs) by one-step in situ oxidation of a 2D V 2 C MXene. The VO@VCM delivers a high capacity of 226 mA h g −1 , superior rate performance, and long cycling stability due to the synergistic effect of the highly conductive MXene and highly active VO 2 . A high capacity VO 2 @V 2 C anode is proposed for aqueous ammonium-ion storage due to the synergistic effect of MXene and VO 2 .
