Method for producing carbonaceous material and lithium ion secondary battery |
| abstract |
(57) [Problem] To provide a negative electrode material for a lithium ion secondary battery, a carbonaceous material having a higher density and a higher capacity than carbonaceous material, a flat discharge potential, and excellent cycle characteristics. And a method for producing a carbonaceous material capable of providing a lithium ion secondary battery having excellent characteristics using the carbonaceous material obtained thereby. SOLUTION: A step of adding a boron compound and / or an aluminum compound or a nitrogen-containing compound to a liquid pitch and then heat-treating to obtain a high softening point pitch, and solidifying the obtained high softening point pitch. Thereafter, a method of producing a carbonaceous material, comprising: a step of pulverizing into fine particles; a step of oxidizing the obtained pulverized substance; and a step of carbonizing and graphitizing the obtained oxidized substance. A lithium ion secondary battery characterized in that the obtained carbonaceous material is a constituent element. |
