Abstract

A negative active material includes a conductive unit bound in island-like form to silicon-based nanowires on a carbonaceous base. Such negative active material may improve the electrical conductivity of the silicon-based nanowires, and suppress separation of the silicon-based nanowires caused from volume expansion, and thus may improve lifetime characteristics of a lithium battery.
