TEMPO-oxidized cellulose nanofiber hydrogel electrolyte for rechargeable Zn-ion batteries

Abstract

A hydrogel composed of TEMPO-oxidized cellulose and zinc perchlorate is proposed as an electrolyte for rechargeable Zn-ion battery. The non-flowable solid-like electrolyte has strong shear-thinning behavior, room temperature conductivity of ∼10−1 S cm−1, and stable Zn/electrolyte interphase. The Zn-ion gel-battery with a β-MnO2 cathode delivers over 100 mA h g−1 at 1.5 V allowing safe energy storage.
