NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND METHOD FOR PRODUCING SAME |
摘要 |
A nonaqueous electrolyte secondary battery with excellent charging/discharging cycle characteristics is provided, more specifically a nonaqueous electrolyte secondary battery in which deterioration of the conductivity of a negative electrode due to charging/discharging cycle is suppressed and a method for manufacturing the same are provided. The nonaqueous electrolyte secondary battery includes: a positive electrode and a negative electrode that are capable of reversibly absorbing and desorbing Li ions; and a nonaqueous electrolyte having lithium ion conductivity. The negative electrode includes a collector and active material particles that are disposed on a surface of the collector. The active material particles include Si and at least one element R selected from the group consisting of Sn, In, Ga, Pb and Bi. Metallic bond including the element R is formed between the active material particles. |
