Inorganic Colloidal Electrolyte for Highly Robust Zinc-Ion Batteries.

ABSTRACT: Zinc-ion batteries (ZIBs) is a promising electrical energy storage candidate due to its eco-friendliness, low cost, and intrinsic safety, but on the cathode the element dissolution and the formation of irreversible products, and on the anode the growth of dendrite as well as irreversible products hinder its practical application. Herein, we propose a new type of the inorganic highly concentrated colloidal electrolytes (HCCE) for ZIBs promoting simultaneous robust protection of both cathode/anode leading to an effective suppression of element dissolution, dendrite, and irreversible products growth. The new HCCE has high Zn²⁺ ion transference number (0.64) endowed by the limitation of SO₄^2-, the competitive ion conductivity (1.1 × 10^-2 S cm^-1<
