Guest-species-incorporation in manganese/vanadium-based oxides: Towards high performance aqueous zinc-ion batteries

Abstract

Aqueous zinc-ion batteries (AZIBs) are considered as a promising alternative to the current lithium-ion battery system due to their environmental benignity, high safety, and cost-effectiveness. Recently, significant research progress has been achieved in the development of manganese/vanadium oxides for AZIBs via guest species incorporation, whereby the intrinsic capacity and cycling stability have been enhanced through improving the structural stability and accelerating the Zn 2+ /e - transportation. In this review, we present an overview of the recent advances in the guest species incorporation of manganese/vanadium oxides for AZIBs. The crystal structures and zinc storage mechanisms have been analyzed with considerations of effects of the various types of guest species incorporated into manganese/vanadium oxides. We also summarized the design strategies, structural advantages and future perspectives of the guest species incorporation for the well-established research in AZIBs.
