Aluminium vanadate with unsaturated coordinated V centers and oxygen vacancies: surface migration and partial phase transformation mechanism in high performance zinc-ion batteries

Abstract

Aluminium vanadate with unsaturated coordinated V centers and oxygen vacancies shows excellent Zn2+ storage due to the low Zn2+ migration barrier along the (001) surface, the co-(de)intercalation mechanism of H+/Zn2+ and the partial transformation.
