Abstract

Highly electronic conductive nanocomposites comprising VO₂ nanoplates decorated onto multiwalled carbon nanotubes/graphene nanoribbons (MWCNT/GONR) are designed and synthesised. The optimal composite positive electrode exhibits a high capacity (428 mA h g⁻¹ at 1 A g⁻¹), ultrahigh rate performance (208 mA h g⁻¹ at 50 A g⁻¹), and extremely long life (10 000 cycles) in aqueous Zn-ion batteries (AZIBs).
