Multiple heterostructures, rich oxygen vacancies and expansion counteraction effect co-boosted VO2/V2O3/V6O13@nitrogen-doped carbon nanosheets as a high-performance cathode for aqueous zinc-ion batteries

In this study, a novel cathode material comprising VO 2 /V 2 O 3 /V 6 O 13 @nitrogen-doped carbon nanosheets (denoted as VO 2 /V 2 O 3 /V 6 O 13 @N-C) with abundant oxygen vacancies was synthesised for aqueous zinc-ion batteries (AZIBs). The synthesis was achieved via...
