Preparatnon of spinel manganate lithium for positive pole material of li -ion battert

It is a effective approach for reducing cost of Li -ion battery to make spinel manganate lithium. The preparation technologies for manganate lithium have been discussed in this paper. Characteristics and disadvantages of these technologies have been indicated, and some improvement ideals for the technologies have been given. Information on production of manganate lithium can be found in the paper.
