NONAQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
Enhancement of the storage property at a high temperature and discharge characteristics at a low temperature of a nonaqueous electrolyte secondary cell is intended. A negative electrode material which is prepared by covering the surface of a nucleus made of a graphite powder with a carbonaceous matter, the graphite powder having a specified plane interval, spectrum value, mean particle size, specific surface area, tapping density, and (110)/(004) X-ray peak intensity ratio, is used in the nonaqueous electrolyte secondary cell. <IMAGE> |
