Manufacturing method of lithium-ion battery negative-electrode material effectively buffering volume change effect of silicon |
| abstract |
A manufacturing method of a lithium-ion battery negative-electrode material effectively buffering a volume change effect of silicon. The method comprises the following steps: preparing modified graphene nanoplatelets (S01); growing silicon nanospheres on the graphene nanoplatelets to obtain a graphene nanoplatelet-silicon nanosphere composite material (S02); depositing, by means of atom layer deposition, a metal oxide layer on the graphene nanoplatelet-silicon nanosphere surface (S03); performing electrospinning and calcination to obtain a carbon nanofiber composite material (S04); performing an acid treatment on the carbon nanofiber composite material to remove the metal oxide layer and form a pore structure (S05); and forming a carbon coating layer outside of the carbon nanofiber composite material (S06). The manufacturing method of the present invention has a simple manufacturing process, and the material has an accurate and controllable pore structure to effectively buffer volume expansion during a charging-discharging process. In addition, a carbon coating layer is formed as an outmost layer to further protect silicon nanospheres, thus ensuring integrity of an electrode structure, and improving stability of the electrode structure. |
