Method and system for target-based electric field decoupling for electrochemical model

Abstract

The invention discloses method and system for target-based electric field decoupling for an electrochemical model. The method includes selecting one endpoint of a negative/positive electrode region as a starting point and the other endpoint as an end point; providing a trial solution of solid-phase and liquid-phase potentials of the starting point empirically, obtaining solid-phase/liquid-phase current of the end point according to the trial solution; obtaining a tentative solution that satisfies boundary value conditions by iterative approximation; designating the tentative solution satisfying the boundary value conditions as a deterministic solution of the solid phase potential and the liquid phase potential of the starting point; and obtaining the microscopic physical quantity of any spatial point in the positive electrode region/negative electrode region in the electric field based on the deterministic solution of the solid phase/liquid phase current, the solid phase and liquid phase potentials at the starting point.
