Secondary battery model

Simulations of secondary batteries using 1D and 2D models enable the development of optimal systems and the reduction of development time.

A detailed explanation of the development and system simulation of secondary batteries based on "gPROMS." You can view a case study on lead-acid battery modeling. There is a library for lead-acid batteries. For lithium-ion batteries, we provide support through custom modeling. By combining 1D and 2D models for verification, it is possible to calculate more accurate data and comprehensively consider the physical and chemical phenomena occurring in each battery component. We can also address issues related to battery operation. <1D Model> Mass balance of components Electrolyte and solid phase potentials - Ohm's law and concentrated solution theory Charge conservation (electrical neutrality) Electric double layer at the electrode/electrolyte interface Changes in porosity and loss of electrode surface area Electrochemical reactions - Butler-Volmer equation Sub-models connected through boundary condition systems Battery capacity loss <2D Model> 2D profiles of current, potential, and component concentration Ion transport represented by a more advanced approach: Maxwell-Stefan-Plank diffusion
