POSITIVE ELECTRODE MIXTURE AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
An object of the present invention is to provide a positive electrode mixture capable of conducting stable charging and discharging with a less amount of gasses generated which has an operating voltage or an initial crystal phase transition voltage of not less than 4.5 V on the basis of lithium. The present invention relates to a positive electrode mixture comprising carbon black having a bulk density of not more than 0.1 g/cm3, a crystallite size of 10 to 40 Å, an iodine adsorption of 1 to 150 mg/g, a volatile content of not more than 0.1% and a metal impurity content of not more than 20 ppm, and a positive electrode active substance having an operating voltage or an initial crystal phase transition voltage of not less than 4.5 V on the basis of lithium. |
