PURPOSE: A carbon capsule anode is provided to effectively store lithium by using carbon capsules with a hollow core structure which consists of a mesoporous external angle shell. CONSTITUTION: A carbon capsule anode comprises a carbon capsule with a hollow core structure which comprises a mesoporous outer shell. The carbon capsule with a hollow core structure consists of a 3-dimensional connection structure in a hollow inside, in a mesoporous path, and between interstices between external particles. The particle diameter of the hollow pores which composes a carbon capsule with the hollow core structure is 20-100 nm, the diameter of the mesopore is 2-10 nm, and the thickness of the mesoporous outer cell is 20-100 nm. |
