Abstract
A method for preparing a swelling-inhibited silicon-carbon composite anode material with increased capacitance includes nanocrystallization of a silicon material to obtain a primary nano-silicon material in a protective environment, self-assembling the primary nano-silicon material with a first carbon source and a macromolecular polymer, and then adding a second carbon source for the self-assembly to obtain a secondary nano-silicon material with a layered structure. The method further includes granulating the secondary nano-silicon material to obtain a precursor, and sintering the precursor to obtain the silicon-carbon composite anode material. The method is simple and easy to control, and is tailored to industrial production. A battery with the silicon-carbon composite anode material on an anode electrode is also disclosed.
