    摘要: An electrode is formed of a ternary composite of silicon, carbon, and carbon filter foil, for lithium ion batteries. Also described is a method for manufacturing silicon/carbon/carbon fiber foil composite electrode for lithium batteries, including: mixing silicon and an organic substance capable of forming carbon after heat treatment, in a solvent, to form a slurry; immersing the carbon fiber foil in said slurry until the slurry coats on and penetrates into the carbon fiber foil; and heating the carbon fiber foil, which has been coated and penetrated with the slurry, in an inert gas atmosphere or all inert gas atmosphere mixed with a reductive gas at a temperature of at least 400° C. for at least 2 hours.
