ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTIC SOLUTION BATTERY AND ITS MANUFACTURING METHOD, ELECTRODE FOR NONAQUEOUS ELECTROLYTIC SOLUTION BATTERY, AND NONAQUEOUS ELECTROLYTIC SOLUTION BATTERY

摘要

PPROBLEM TO BE SOLVED: To provide an active material in which discharge performance of a nonaqueous electrolyte battery using lithium titanate as the active material can be improved. PSOLUTION: An organic compound has been mixed which becomes a precursor of a carbonaceous material from a stage in which lithium titanate is synthesized from a lithium compound and a titanium compound by heat-treatment. At this time, the heat-treatment is divided into two stages of the low temperature heat-treatment and the high temperature heat-treatment, and to form a baked body prior to the high temperature heat-treatment is preferable. Polyvinyl alcohol is preferable as the organic compound to become the precursor of the carbonaceous material. PCOPYRIGHT: (C)2006,JPO&NCIPI
