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.

High energy materials for a battery and methods for making and use

A composition for forming an electrode. The composition includes a metal fluoride, such as copper fluoride, and a matrix material. The matrix material adds capacity to the electrode. The copper fluoride compound is characterized by a first voltage range in which the copper fluoride compound is electrochemically active and the matrix material characterized by a second voltage range in which the matrix material is electrochemically active and substantially stable. A method for forming the composition is included.
