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 LiMn(BO). 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.

Electrochemical device comprising lithium manganese borate compounds

This invention relates generally to electrode materials, electrochemical cells employing such materials, and methods of synthesizing such materials. The electrode materials have a crystal structure with a high ratio of Li to metal M, which is found to improve capacity by enabling the transfer of a greater amount of lithium per metal, and which is also found to improve stability by retaining a sufficient amount of lithium after charging. Furthermore, synthesis techniques are presented which result in improved charge and discharge capacities and reduced particle sizes of the electrode materials.
