| titleOfInvention | Powder for negative electrode material of lithium ion secondary battery, lithium ion secondary battery negative electrode and capacitor negative electrode using the same, lithium ion secondary battery and capacitor |
| abstract | Lithium ion secondary having a conductive carbon film on the surface of the lower silicon oxide powder, the particle size distribution of the silicon oxide powder is 1 μm ≦ D50 ≦ 20 μm, and D50 and D10 satisfy 1.4 ≦ D50 / D10 ≦ 2.4 Battery negative electrode powder. The thickness of the conductive carbon film is 1.5 nm or more and 7.5 nm or less, the specific surface area measured by the BET method is 0.3 m 2 / g or more and 7.0 m 2 / g or less, The occupying ratio is preferably 0.5% by mass or more and 10% by mass or less. It is preferable that the total content of tar components measured by TPD-MS is 1 to 4,000 ppm by mass, and the maximum value P1 of halo derived from SiO x and the value of the strongest peak of Si (111) by XRD measurement P2 preferably satisfies P2 / P1 <0.01. Thereby, the powder for negative electrode materials used for the lithium ion secondary battery which has a large discharge capacity and favorable cycle characteristics and can withstand use at a practical level can be provided. |
