Abstract
A method for establishing an electrochemical model for an ion battery is provided. The ion battery includes a negative electrode region, a positive electrode region, and a diaphragm arranged between the negative electrode region and the positive electrode region. The negative electrode region includes a negative electrode current collector, a negative electrode liquid phase and a negative electrode solid phase. The positive electrode region includes a positive electrode current collector, a positive electrode liquid phase and a positive electrode solid phase. The method includes: defining negative electrode parameters for describing a solid-liquid interface structure between the negative electrode liquid phase and the negative electrode solid phase in the negative electrode region and positive electrode parameters for describing a solid-liquid interface structure between the positive electrode liquid phase and the positive electrode solid phase in the positive electrode region; establishing a partial differential equation set and a boundary condition for describing a charging process and a discharging process of the ion battery based on the negative electrode parameters and the pos…
