  • GRAPHITE NEGATIVE ELECTRODE MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
    Publication number: 20260054994
    Abstract: A graphite negative electrode material, a preparation method therefor and an application thereof. The surface of the graphite negative electrode material is provided with a macroporous structure and a mesoporous structure. In the macroporous structure, the ratio R of depth H of the macropores to size D of the macropores satisfies 0<R<60, where R=H/D. In the mesoporous structure, the ratio r of depth h of the mesopores to size d of the mesopores satisfies 0<r<250, where r=h/d. The preparation method comprises: dispersing a pore-forming agent solution on the surface of graphite by means of a mechanical force, and carrying out heat treatment in a protective atmosphere to obtain the graphite negative electrode material. The pore-forming agent is water-soluble. The surface of the graphite negative electrode material is provided with a macroporous structure and a mesoporous structure at the same time.

  • Systems and methods for electric vehicle charging
    Patent number: 11790392
    Abstract: The present disclosure relates to a system and a method for electric vehicle charging. The system may perform the method to: receive a request for charging station recommendation from a client terminal; determine at least one charging station within a preset distance range of the client terminal; determine an evaluation for each of the at least one charging station based on one or more evaluation parameters; and transmitting, by the first computing device, the evaluation of the each of the at least one charging station and an identifier of the each of the at least one charging station to the client terminal.
