摘要：
A negative active material for rechargeable lithium batteries and a method of manufacturing the negative active material are provided. The negative active material for rechargeable lithium batteries includes at least one generally spherical assembly having flake-shaped materials that are capable of doping and dedoping lithium, and are arranged in a generally spherical shape defining a central pore. The negative active material imparts improved cycle-life characteristics.
