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 S cm, and stable Zn/electrolyte interphase. The Zn-ion gel-battery with a β-MnO cathode delivers over 100 mA h g at 1.5 V allowing safe energy storage.

摘要

一种由TEMPO氧化纤维素和高氯酸锌组成的水凝胶被提议作为可充电锌离子电池的电解质。这种不可流动的类固体电解质具有很强的剪切变稀行为，室温电导率约为10 S/cm，并且锌/电解质界面稳定。具有β-MnO阴极的锌离子凝胶电池在1.5 V电压下可提供超过100 mA h/g的电量，实现安全的能量存储。
