High energy materials for a battery and methods for making and use
View Patent ↗A composition for forming an electrode. The composition includes a metal fluoride compound doped with a dopant. The addition of the dopant: (i) improves the bulk conductivity of the composition as compared to the undoped metal fluoride compound; (ii) changes the bandgap of the composition as compared to the undoped metal fluoride compound; or (iii) induces the formation of a conductive metallic network. A method of making the composition is included.
