摘要:
A battery electrode composition is provided that comprises composite particles. Each composite particle may comprise, for example, active fluoride material and a nanoporous, electrically-conductive scaffolding matrix within which the active fluoride material is disposed. The active fluoride material is provided to store and release ions during battery operation. The storing and releasing of the ions may cause a substantial change in volume of the active material. The scaffolding matrix structurally supports the active material, electrically interconnects the active material, and accommodates the changes in volume of the active material.
摘要:
Metal-ion battery cells are provided that take advantage of the disclosed “doping” process. The cells may be fabricated from anode and cathode electrodes, a separator, and an electrolyte. A metal-ion additive may be incorporated into (i) one or more of the electrodes, (ii) the separator, or (iii) the electrolyte. The metal-ion additive provides additional donor ions corresponding to the metal ions stored and released by anode and cathode active material particles. An activation potential may then be applied to the anode and cathode electrodes to release the additional donor ions into the battery cell.
