Title:
NEGATIVE ELECTRODE FOR ALL-SOLID BATTERY AND ALL-SOLID BATTERY INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2015/152214
Kind Code:
A1
Abstract:
The objective of the present invention is to provide an all-solid battery having high energy density. The aforementioned problem can be solved by means of a negative electrode for an all-solid battery, said electrode including: a carbonaceous material that has a true density, determined by a butanol method of the present invention, of 1.30-1.70 g/cm3, a specific surface area of 0.5-50.0 m2/g, an average particle size (Dv50) of 1-50 µm, and a butanol true density (ρBt (g/cm3)) and combustion peak (T (°C)) according to differential thermal analysis that satisfy belowmentioned formula (1) 300 ≤ T-100×ρBt ≤ 570 (1); and a solid electrolyte.
