Title:
The electrode for nonaqueous electrolyte accumulation-of-electricity elements
Document Type and Number:
Japanese Patent JP6164012
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide: an electrode for nonaqueous electrolyte electricity-storage devices superior in charge and discharge cycle characteristics; and a nonaqueous electrolyte power storage device arranged by use of such an electrode.SOLUTION: An electrode for nonaqueous electrolyte electricity-storage devices comprises a mixture layer including an active material containing silicon, scale-like graphite, and a polyimide-based binding agent. The ratio (A/B) of the average particle diameter (A) of the active material to the average particle diameter (B) of the scale-like graphite is 0.6 or less. The content of the polyimide-based binding agent in the mixture layer is 10 mass% or more. A nonaqueous electrolyte power storage device is arranged by use of the electrode for nonaqueous electrolyte electricity-storage devices.
