N-Methylpyrrolidone assisted tetrachlorobenzoquinone intercalating V₂O₅as cathode for aqueous zinc-ion battery

Abstract

Vanadium oxide (V2O5) is intercalated by tetrachlorobenzoquinone (TCB) through a one-step solvothermal method using N-methylpyrrolidone (NMP)/water solvent.

“…Their magnetic and electronic transitions have recently been proposed for volatile resistive switching devices and neuromorphic computing . Most of them undergo metal–insulator transitions ( MITs ) often associated with changes in optical properties. , The versatility of a vanadium cation to assume different valence states, its changing local environment, and the flexibility of the framework geometry of coordination polyhedra allow for the reversible intercalation of various ions, enabling for instance medical or electrochemical − applications.…”

Unravelling the effect of benzoquinone intercalators on the aqueous zinc-ion storage performance toward a vanadium pentoxide cathode

“…4,5 The low oxidation–reduction potential (−0.76 V against a standard hydrogen electrode) and high theoretical specific capacity (820 mA h −1 or 5851 mA h cm −3 ) make ZIBs promising alternatives. 6,7 Compared to lithium ions, bivalent zinc ions possess a larger ionic radius and strong coulombic attraction, leading to slower kinetics of interfacial ionic transfer and redox reaction. As a result, the rate capability and lifespan of ZIBs are usually unsatisfactory.…”

Tuning the number of redox groups in the cathode toward high rate and long lifespan zinc-ion batteries

“…Considerable effort has been devoted to research on inorganic cathode materials, such as manganese/vanadium oxides and Prussian blue analogues. 5–9 However, their performance is susceptible to slow kinetics and structural collapse during successive ion insertion and removal processes, causing difficulties in their further applications.…”
