Starting material of negative electrode material for nonaqueous secondary batteries, negative electrode material for nonaqueous secondary batteries, negative electrode for nonaqueous secondary batteries, and nonaqueous secondary battery |
| abstract |
Provided are: a negative electrode material for a nonaqueous secondary battery, with which a nonaqueous secondary battery having a high capacity and excellent rapid charge-discharge characteristics as well as an excellent balance between the low-temperature input-output characteristics and the high-temperature storage characteristics can be provided; a negative electrode for a nonaqueous secondary battery, which contains the same; and a nonaqueous secondary battery. The negative electrode material for a nonaqueous secondary battery contains a graphite that contains an amorphous carbonaceous material in at least a part of the surface; has a cumulative pore volume of 0.100 mL/g or less in a pore size range of 0.01 µm to 1 µm; and satisfies at least one of the following conditions (1) and (2) in a DTA curve obtained by differential thermal analysis (DTA) in an air stream: (1) the negative electrode material has no exothermic peak in a temperature range of 550°C to 650°C; and (2) the negative electrode material has an exothermic peak in a temperature range of 550°C to 650°C, and the area of the exothermic peak is larger than 0 µv·s/mg but 90 µv·s/mg or smaller. |
