Abstract
A disclosed battery may include an anode, a cathode positioned opposite to the anode, a protective sheath disposed on the cathode, an electrolyte, and a separator. A polymeric network disposed on the anode and may include carbonaceous materials grafted with a plurality of fluorinated polymer chains cross-linked into a lattice. The lattice may produce an alkali metal fluoride in response to operational cycling of the battery. The alkali metal fluoride may be configured to suppress alkali metal dendrite formation from the anode. The protective sheath disposed on the cathode may include a tri-functional epoxy compound and a di-amine oligomer-based compound that can chemically react with each other. The electrolyte may disperse throughout the cathode and contact with the anode. As a result, the electrolyte may transport the alkali ions between the cathode and the anode. The separator may be positioned between the anode and the cathode.
