Abstract
A process is provided for making nano-sized or sub-micron sized oxides of lithium and a transition metal. The desired size is generally in the range 10 nm to 1000 nm and preferably in the range 10 nm to 100 nm. The particles have a narrow size distribution. The process includes milling and re-firing under controlled conditions so that crystallites of the desired particle size are grown.
Claims11
A process for producing a nano-sized or sub-micron oxide of lithium and a transition metal comprising:
- a. milling a coarse lithium transition-metal oxide;
- and,
- b. re-firing the lithium transition-metal oxide
A lithium-transition metal oxide with a particle size between 10 nm and 1000 nm and a standard deviation of no more than 20%.
