In recent years, colloidal nanoparticles have proven to be performing exceptionally in batteries, supercapacitors, and hydrogen storage systems.
Benefited from the development of colloidal soft materials-based electrolytes and electrode materials, the electrochemical performance of energy storage devices has been greatly improved.
Benefiting from stable colloid additives, aqueous colloid electrolytes as fast ion carriers can modulate the typical electrolyte system for improving reversible plating/stripping on Zn anode for high-performance Zn ion batteries 43, 44.
Colloidal soft matter provides approaches for the innovative design of energy storage devices. The structures and components of colloidal soft electrolytes intrinsically determine the energy density. Colloidal soft matter-based electrode achieves high energy outputs owing to well-controlled porous and specific surface area.
However, capacity loss and low Coulombic efficiency resulting from polyiodide cross-over hinder the grid-level battery performance. Here, we develop colloidal chemistry for iodine-starch catholytes, endowing enlarged-sized active materials by strong chemisorption-induced colloidal aggregation.
