The research on modeling of lithium-ion battery is to find the relationship between design variables and electrochemical performance of the batteries by studying the internal structure of batteries and analyzing the charge-discharge behavior, using basic physical and chemical theory, including electrode kinetics, ion diffusion and electrolyte solution theory. The research advance on the mathematical modeling of lithium ion battery for the past few years was reviewed. The basic theories and present models, including models of battery performance prediction, thermal behavior, capacity fade and cycling life prediction, were summarized. And finally the future aspect on mathematical modeling of lithium ion battery is expected.
