Energy Storage Carriers

Research and Practice of Colloids in Energy Storage Carriers

The special structural characteristics of colloidal materials endow them with rich properties. Colloidal materials have been shown to exhibit semimetallic properties under chemical, electrochemical or photochemical reduction conditions, which undoubtedly enhances their application prospects in the field of energy storage.

Many colloidal materials have been investigated as energy storage carriers. For example, redox-active colloids (RACs) prepared from cross-linked colloidal poly(vinylbenzyl chloride) (xPVBC) can serve as discrete charge carriers, containing redox pendants within well-defined 3D geometries for facile charge transmission. Based on efficient energy storage with a high degree of morphology control, RACs hold considerable promise for emerging energy storage applications, whether as single particles, adsorbed films, or dispersed phases. Colloidal ZnO semiconductor nanocrystals doped with colloidal iron exhibit extremely large capacitance values comparable to commercial supercapacitor materials. This indicates the promising application of these colloidal nanocrystals in energy storage technologies based on solution or solution processing.
