  "textContent": "A high capacity negative electrode for a non-aqueous electrolyte secondary battery which has low declining rate in discharge capacity caused by charge/discharge cycles by improving the electronic conductivity on the surface of the particles of the negative electrode material. The negative electrode material is formed by coating part of or the entire surface of solid phase A comprising a nucleus particle with the solid phase B. The solid phase A contains silicon as a constituent element. The solid phase B is composed of a solid solution or intermetallic compounds composed of silicon and at least one another element selected from a group comprising of group 2 elements, transition elements, group 12 elements , group 13 elements and group 14 elements (exclusive of carbon and silicon) of the Periodic Table.",
