Oxide coatings on lithium oxide particles

摘要: The present invention generally relates to unique coatings for use with energy storage particles, such as lithium oxide energy storage materials. The invention provides unique coat ings for particles, unique particle/coating combinations, and unique methods for making coatings and/or coated particles. In one aspect of the invention, a particle is formed having a core and a coating. The particle may comprise a core having a material Such as LiFePO, and a coating. The particle may be formed, in some embodiments, by using a non-stoichio metric combination of salts or other precursors, and sintering the same to form particles. LiFePO may form as the core of the particle, while the remaining materials may form a coat ing around the LiFePO. Typically, the LiFePO is crystalline while the coating is generally amorphous, and in some instances, the coating may prevent large crystals of LiFePO from forming. However, in …
