Abstract
To study the electrochemical performance of lithium ion battery for electric vehicles, this paper uses numerical simulation method combined with experimental data, to make a simulation study of one-dimensional voltage features, electrolyte concentration distribution and current density distribution of the lithium battery. The results show that the electrochemical performance of lithium ion battery for electric vehicle affects the stability of the lithium ion battery, and is closely related to the life of lithium ion battery. At last, it is concluded that the obtained data and conclusions have strong theoretical significance and guiding value for engineering application of lithium batteries.
