摘要： The present invention generally relates to carbophosphates and other compounds. Such compounds may be used in batteries and other electrochemical devices, or in other applications such as those described herein. One aspect of the invention is generally directed to carbophosphate compounds, i.e., compounds containing carbonate and phosphate ions. For example, according to one set of embodiments, the compound has a formula Ax(M)(PO4)a(CO3)b, where M comprises one or more cations. A may include one or more alkali metals, for example, lithium and/or sodium. In some cases, x is greater than about 0.1, a is between about 0.1 and about 5.1, and b is between about 0.1 and about 5.1. In certain embodiments, the compound may have a unit cell atomic arrangement that is isostructural to to unit cells of the minerals sidorenkite, bonshtedtite, bradleyite, crawfordite, or ferrotychite. In some embodiments, the compound may have a formula Ax(M)(YO4)a(XO3)b, where A comprises one or more alkali metals, M comprises one or more cations, X includes B, C, and/or N, and Y includes Si, P, As, S, V, Nb, Mo, and/or W. In some cases, x is greater than about 0.1, a is between about 0.1 and about 5.1, and b is between about 0.1 and about 5.1. Other aspects of the invention are generally directed to techniques for making or using such compounds, kits involving such compounds, and the like.

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 coatings 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 LiFePO4, and a coating. The particle may be formed, in some embodiments, by using a non-stoichiometric combination of salts or other precursors, and sintering the same to form particles. LiFePO4 may form as the core of the particle, while the remaining materials may form a coating around the LiFePO4. Typically, the LiFePO4 is crystalline while the coating is generally amorphous, and in some instances, the coating may prevent large crystals of LiFePO4 from forming. However, in other embodiments, a coating may be applied to a particle after formation of the particle to form a core/coating structure. The particles disclosed herein may have a relatively high energy capacity, and thus may find use in batteries and other energy storage devices. Other aspects of the invention relate to devices comprising such particles, methods of making such particles, kits for making such particles, methods of promoting the making or use of such particles, and the like.
