摘要：
A negative electrode, a lithium battery employing the negative electrode, and a method of preparing the negative electrode. The negative electrode includes a current collector, and a negative electrode active material layer disposed on the current collector. The negative electrode active material layer includes: composite negative electrode active material particles comprising tin (Sn), and conductive metal particles. The conductive metal particles form an intermetallic compound with the Sn, and an average particle size of the conductive metal particles is at least 10 μm.
