摘要

Disclosed are a negative active material of a rechargeable lithium battery and a rechargeable lithium battery including a negative electrode, and the negative electrode includes a negative active material layer including a negative active material represented by the following Chemical Formula 1.
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ X-Ra-Rb
In Chemical Formula 1,
X is an active material which comprises a metal and whose functional group has been reacted with a silane coupling agent,
Ra is a residual group from a silane coupling agent, and
Rb is a polymer including a first repeating unit represented by the following Chemical Formula 2a.
In Chemical Formula 2a,
R 10 to R 13 are the same or different, and are hydrogen; or a substituted or unsubstituted C1 to C5 alkyl group, and n 1 is an integer ranging from 1 to 100000 and * is a chemical bond.
