| titleOfInvention | A kind of preparation method of lithium titanate of negative pole material of nanoscale lithium ion battery |
| abstract | The present invention relates to a kind of preparation method of lithium titanate of negative pole material of nanoscale lithium ion battery, comprise the following steps: titanium source, dispersant, deionized water are mixed to form titaniferous solution by (1), stir lower hydrolysis, and by product collected by centrifugation; (2) added in lithium-containing solution by the centrifugal product obtained and mix, carry out liquid phase reactor, the sediment generated after reaction is lithium titanate precursor, and wherein Li and Ti mol ratio is 4:5 ~ 5:1; (3) to the calcining of step (2) gained lithium titanate precursor, then naturally cool to room temperature, obtain lithium titanate of negative pole material of nanoscale lithium ion battery.Compared with prior art, the present invention at low temperatures, liquid phase reactor is utilized to synthesize nanoscale lithium titanate, evenly, domain size distribution is narrower, and reacts low for equipment requirements for the material composition prepared, condition is changeable adjustable, be easy to suitability for industrialized production, this material has excellent specific capacity performance and cycle performance simultaneously, as having excellent chemical property during lithium ion battery negative. |
