Title:
METHOD FOR ESTABLISHING ELECTROCHEMICAL MODEL OF ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/246445
Kind Code:
A1
Abstract:
The present disclosure relates to a method for establishing an electrochemical model of an ion battery. An ion battery comprises a negative electrode area, a positive electrode area and a separator arranged between the negative electrode area and the positive electrode area, the negative electrode area comprising a negative electrode current collector, a negative electrode liquid phase and a negative electrode solid phase, and the positive electrode area comprising a positive electrode current collector, a positive electrode liquid phase and a positive electrode solid phase. The method comprises: setting a negative electrode parameter describing a solid-liquid interface structure between the negative electrode liquid phase and the negative electrode solid phase in the negative electrode area, and a positive electrode parameter describing a solid-liquid interface structure between the positive electrode liquid phase and the positive electrode solid phase in the positive electrode area; on the basis of the negative electrode parameter and the positive electrode parameter, establishing a partial differential equation system and a boundary condition for describing a charging process and a discharging process of the ion battery; and establishing an electrochemical model of the ion battery by solving the partial differential equation system, wherein the solid-liquid interface structure of the negative electrode area and the solid-liquid interface structure of the positive electrode area are each a folded structure and each comprise a plurality of repeated folded sub-structures.
