Abstract The present invention relates to the technology of room temperature secondary lithium cell. The secondary lithium cell consists of positive pole, negative pole, organic electrolyte solution or polymer electrolyte, and its negative pole is made of carbon with deposited nanometer alloy on its surface. It the composite material, carbon material is used as skeleton and the nanometer alloy is dispersed onto the surface of the carbon material. The secondary lithium cell of the present invention has high capacity, good circulation performance, large current charge and discharge resistance, and is safe, reliable and friendly to environment. It may be used in mobile telephone, notebook computer and other fields.
