Abstract：
 This invention relates to a compound negative material with micro-balls of active carbon covering metals and its preparation method characterizing in putting metal particles in hollow carbon micro-balls to make up of the structure of the material, in which, said metal is a Li-stored active metal, the mass percentage is 30-80% taking resorcin, methanal, a metal or its metal oxide as the raw material to be prepared by a method of reverse micelle latex polymerization and high temperature carbonization recovery.
