11.6: Colloids

A few solid substances, when brought into contact with water, disperse spontaneously and form colloidal systems. Gelatin, glue, starch, and dehydrated milk powder behave in this manner. The particles are already of colloidal size; the water simply disperses them. Powdered milk particles of colloidal size are produced by dehydrating milk spray

Aqueous Colloid Flow Batteries Based on Redox-Reversible

Aqueous redox flow batteries (ARFBs) exhibit great potential for large-scale energy storage, but the cross-contamination, limited ion conductivity, and high costs of ion-exchange membranes restrict the wide application of ARFBs. Herein, we report the construction of aqueous colloid flow batteries (ACFBs) based on redox-active polyoxometalate
