Layered porous Mn_0.18V₂O₅@C with manganese and carbon provided by a metal–organic framework precursor as a cathode material for aqueous zinc-ion batteries

Abstract

Manganese and carbon derived from organometallic frameworks contribute to the excellent electrochemical properties of vanadium-based oxides.

Porous layered ZnV2O4@C synthesized based on a bimetallic MOF as a stable cathode material for aqueous zinc ion batteries

“…A similar polarization behavior can also be observed in recently reported vanadium-based cathode materials. 51 Although polarization behavior is induced at high scanning rates, their redox peak currents increase with increasing scanning rates, which implies that the electrochemical polarization is capable of raising the electrochemical reaction activity. The typical electrochemical reaction kinetics involves pseudocapacitive processes and diffusion control processes.…”
