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.
