An electrophoretic medium that may be incorporated into an electrophoretic display includes a dispersion that may be contained in a plurality of microcapsules or microcells or a polymeric continuous phase. The dispersion may include a non-polar fluid, a plurality of first charged particles; and an inhibitor of photo-thermally induced polymerization that inhibits potential cross-linking between the particles and/or the microcells or polymeric continuous phase. The inhibitor may be a compound having an unsaturated hydrocarbon ring and at least one of a hydroxyl group, a carbonyl group, and a nitroso group. The plurality of microcells or polymeric continuous phase and a coating of the particles may include a polymeric material that includes (meth)acrylates.

An improved rechargeable battery may utilize materials that are entirely solid-state. The battery may utilize at least one organic active material for an electrode. The battery may utilize a cathode that comprises quinone(s). An electrolyte of the battery may be an ion-conducting inorganic compound. An anode of the battery may comprise an alkali metal. Further, a carbonyl group of the quinone(s) of the cathode may be reduced into a phenolate and coordinated to an alkali metal ion during discharge and vice versa during charging.
