Abstract

See full text

The present invention generally relates to certain lithium materials, including lithium manganese borate materials. Such materials are of interest in various applications such as energy storage. Certain aspects of the invention are directed to lithium manganese borate materials, for example, having the formula LixMny(BO3). In some cases, the lithium manganese borate materials may include other elements, such as iron, magnesium, copper, zinc, calcium, etc. The lithium manganese borate materials, according to one set of embodiments, may be present as a monoclinic crystal system. Such materials may surprisingly exhibit relatively high energy storage capacities, for example, at least about 96 mA h/g. Other aspects of the invention relate to devices comprising such materials, methods of making such materials, kits for making such materials, methods of promoting the making or use of such materials, and the like.
