Abstract
Official abstract text for this publication.
Li-ion batteries are provided that include a cathode, an anode comprising active particles, an electrolyte ionically coupling the anode and the cathode, a separator electrically separating the anode and the cathode, and at least one hydrofluoric acid neutralizing agent incorporated into the anode or the separator. Li-ion batteries are also provided that include a cathode, an anode comprising active particles, an electrolyte ionically coupling the anode and the cathode, and a separator electrically separating the anode and the cathode, where the electrolyte may be formed from a mixture of an imide salt and at least one salt selected from the group consisting of LiPF6, LiBF4, and LiClO4. Li-ion battery anodes are also provided that include an active material core and a protective coating at least partially encasing the active material core, where the protective coating comprises a material that is resistant to hydrofluoric acid permeation.
