In general, the present disclosure is directed to methods for synthesizing vanadium oxide nanobelts, as well as the corresponding chemical composition of the vanadium oxide nanobelts. Also described are materials which can incorporate the vanadium oxide nanobelts, such as including the vanadium oxide nanobelts as a cathode material for use in energy storage applications (e.g., batteries). The vanadium oxide nanobelts described herein display structural characteristics that may provide improved diffusion and/or charge transfer between ions. Thus, batteries incorporating implementations of the current disclosure may demonstrate improved properties such as higher capacity retention over charge discharge cycling.

The present invention belongs to the field of battery materials, and relates to a process for preparing a particulate lithium manganese nickel spinel compound, and materials produced by the process. The process of the invention uses Mn-containing precursors, Ni-containing precursors, Li-containing precursors and optionally M-containing precursor which form substantially no NOx ases during calcination. The particulate lithium manganese nickel spinel compound product of the process may find use in a lithium ion battery.

A positive electrode active material for a non-aqueous electrolyte secondary battery, according to an example of this embodiment, includes a lithium transition metal composite oxide which has a layered structure and contains at least Ni, Al, and Ca.

In addition, the proportion of metal elements other than Li present in a Li layer is 0.6-2.0 mol % with respect to the total amount of metal elements other than Li contained in the composite oxide.

An alumina grain has a single-crystal structure and has an approximate regular octahedral stereoscopic morphology. Eight sides of the alumina grain belong to the {111} family of crystal planes of γ-state alumina, and the grain size is 5-100 μm. The alumina grain is unique in crystal plane exposure and distribution, simple and feasible in preparation, and low in cost, and has higher operability, and thus has good application prospect in the field of catalysis and adsorption.
