| titleOfInvention | Composite graphite particles for non-aqueous secondary batteries, negative electrode material containing them, negative electrode and non-aqueous secondary battery |
| abstract | The objective is to provide a non-aqueous secondary battery having a sufficiently low charge / discharge irreversible capacity during 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 spherical graphite particles and the binder graphite are complexed. The problem was solved by the composite graphite particles for nonaqueous secondary batteries in which the composite graphite particles satisfy at least one selected from the group consisting of at least the following requirements (a) to (g).n n n (a) It contains the composite graphite particle which at least one part of the said spherical graphite particle exposed to the surface. (b) It contains the composite graphite particle which has an incomplete laminated structure of the said spherical graphite particle in the surface vicinity. (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 values are 0.10 or more and 0.30 or less, average circularity is 0.85 or more, tap density is 0.87 g / cm 3 or more and 1.25 g / cm 3 or less, and BET specific surface area is 2.5 m 2 / g or more and 8.0 m 2 / g or less. (e) The pore volume of 0.01 micrometer or more and 2 micrometers or less measured with a mercury porosimetry is 0.05 mL / g or more and 1 mL / g or less. (f) The amount of CO groups present on the surface normalized to the BET specific surface area is not less than 1.15 mol / m 2 and not more than 5 mol / m 2. (g) When the specific electrolyte solution is dripped at the electrode obtained using the said composite graphite particle, the average value of time until the said electrolyte solution disappears completely on an electrode is 180 second or less. |
