Document Type and Number:
WIPO Patent Application WO/2012/081553
Kind Code:
A1
Abstract:
The present invention provides a negative electrode for a non-aqueous electrolyte secondary battery which can be produced at a reduced cost and has a high graphite packing density and consistent quality. The negative electrode for a non-aqueous electrolyte secondary battery is characterized by comprising a negative-electrode current collector and a negative-electrode active material layer disposed on the negative-electrode current collector, and in that the negative-electrode active material layer contains flaky graphite formed through the graphitization of needle coke, granular graphite formed through the graphitization of coke, and a binder.
