| titleOfInvention | Carbon negative electrode material for lithium secondary batteries |
| abstract | (57) [Summary] [Object] The present invention provides a crushed carbon fiber powder as a negative electrode material for a lithium secondary battery, which has a large discharge capacity, high charge-discharge efficiency from the initial stage of the cycle, and excellent cycle characteristics. provide. The carbon negative electrode material for a lithium secondary battery of the present invention is a carbon powder having an aspect ratio of 50 or less obtained by crushing carbon fibers having a fiber diameter of 20 μm or less, which is made of pitch as a raw material, and has a graphitization degree (d is 0. 338 nm or less, Lc is 20 nm As described above, HWHM is high (10 ° or less), the fiber shape is maintained, and the cross-sectional structure of the fiber is controlled (at least the skin portion is radial). Therefore, the discharge capacity, charge-discharge efficiency, and cycle stability are improved. It is possible to provide an excellent powdery carbon material. Furthermore, since the carbon material of the present invention has a large true specific gravity (2 or more), it can greatly contribute to downsizing of the battery. |
