| titleOfInvention | Composite graphite particles for non-aqueous secondary batteries, negative electrode materials containing the same, negative electrodes and non-aqueous secondary batteries |
| abstract | The present invention also provides a nonaqueous secondary battery having a sufficiently low charging / discharging irreversible capacity at the initial cycle even when the active material layer having the negative electrode material on the current collector is densified for high capacity, and the secondary battery is composed of the spherical graphite particles and the binder graphite Wherein the composite graphite particles satisfy at least any one of the following requirements (a) to (g): n (a) a composite graphite particle in which at least a part of the spherical graphite particles are exposed on a surface thereof. (b) composite graphite particles having an incomplete laminated structure of the spherical graphite particles in the vicinity of the surface. (c) When the median diameter of the spherical graphite particles is a and the median diameter of the composite graphite particles is b, the ratio c = a / b is 0.93 or more. (d) Raman R value of not less than 0.10 and not more than 0.30, an average circularity of not less than 0.85, a tap density of not less than 0.87 g / cm 3 and not more than 1.25 g / cm 3, and a BET specific surface area of not less than 2.5 m 2 / g and not more than 8.0 m 2 / g. (e) a pore volume of not less than 0.01 m and not more than 2 m measured by a mercury porosimeter is not less than 0.05 ml / g and not more than 1 ml / g. (f) The amount of CO groups present on the surface normalized by BET specific surface area is 1.15 mu mol / m < 2 > to 5 mu mol / m < 2 >. (g) When the specific electrolyte is dropped onto the electrode obtained using the composite graphite particles, the average time until the electrolyte completely disappears on the electrode is 180 seconds or less. |
