Electrode for nonaqueous electrolyte secondary battery, method for producing same, and nonaqueous electrolyte secondary battery comprising such electrode for nonaqueous electrolyte secondary battery |
摘要 |
An electrode for a non-aqueous electrolyte secondary battery 6 according to the present invention includes: a current collector 3; a first active material layer 2 formed on the current collector 3; and a second active material layer 5 provided on the first active material layer 2, the second active material layer 5 including a plurality of active material particles 4. The plurality of active material particles 4 is mainly of a chemical composition represented as SiOx (0≦̸x<1.2). The first active material layer 2 is mainly of a chemical composition represented as SiOy (1.0≦̸y<2.0, y>x). The area in which the first active material layer 2 is in contact with the plurality of active material particles 4 is smaller than the area in which the current collector 3 is in contact with the first active material layer 2.
