    摘要: A negative active material includes a silicon-based alloy, wherein the silicon-based alloy includes silicon (Si); a first metal (M1) selected from titanium (Ti), vanadium (V), chromium (Cr), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), gallium (Ga), and germanium (Ge), and at least one additional element (A), which is included in the silicon-based alloy and on a surface of silicon-based alloy, selected from carbon (C), boron (B), sodium (Na), nitrogen (N), phosphorous (P), sulfur (S), and chlorine (Cl), and the silicon-based alloy has an internal porosity of about 35% or less. A lithium battery including the negative active material may have improved lifespan characteristics.
