摘要： In an aspect, a Li-ion cell may comprise a densified electrode exhibiting an areal capacity loading of more than about 4 mAh/cm2. For example, the densified electrode may a first electrode part arranged on a current collector and a second electrode part on top of the first electrode part, the second electrode part of the at least one densified electrode having a higher porosity than the first electrode part of the at least one densified electrode. In some designs, the densified electrode may be fabricated by densifying electrode layers via a pressure roller while maintaining a contacting part of the pressure roller at a temperature that is less than a temperature of the second electrode part. In some designs, the applied pressure is a time-varying (e.g., frequency modulated) pressure. In some designs, a drying time for a slurry to produce the densified electrode may range from around 1-120 seconds.

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.

摘要： Battery electrode compositions and methods of fabrication are provided that utilize composite particles. Each of the composite particles may comprise, for example, a high-capacity active material and a porous, electrically-conductive scaffolding matrix material. The active material may store and release ions during battery operation, and may exhibit (i) a specific capacity of at least 220 mAh/g as a cathode active material or (ii) a specific capacity of at least 400 mAh/g as an anode active material. The active material may be disposed in the pores of the scaffolding matrix material. According to various designs, each composite particle may exhibit at least one material property that changes from the center to the perimeter of the scaffolding matrix material.

摘要： In an embodiment, a metal or metal-ion battery cell, includes anode and cathode electrodes, a separator electrically separating the anode and the cathode, and a solid electrolyte ionically coupling the anode and the cathode, wherein the solid electrolyte comprises a material having one or more rearrangeable chalcogen-metal-hydrogen groups that are configured to transport at least one metal-ion or metal-ion mixture through the solid electrolyte, wherein the solid electrolyte exhibits a melting point below about 350° C. In an example, the solid electrolyte may be produced by mixing different dry metal-ion compositions together, arranging the mixture inside of a mold, and heating the mixture while arranged inside of the mold at least to a melting point (e.g., below about 350° C.) of the mixture so as to produce a material comprising one or more rearrangeable chalcogen-metal-hydrogen groups.
