Hierarchical oxygen-containing carbon anode for lithium-ion batteries with large capacity and fast charging capability

摘要

Oxygen is in the form of a functional group, and the oxygen is hierarchically distributed from the surface of the carbon particle to the inside, and the oxygen-containing carbon having an interlayer spacing d ₀₀₂ greater than 0.3357 nm, and the oxygen-containing carbon And a porous graphene layer in the form of a single layer or several layers of graphene covering the anode material for a lithium ion battery.
