The thesis is devoted to the study of the materials for lithium ion secondary battery, which focusing on the various characteristics of the lithium batteries influenced by different chemical materials. Analyzing the discharge characteristics of the cell through the discharge curves of the lithium batteries, as well as the equivalent circuit of the battery discharge.
First of all, it is essential to acquire the knowledge of the battery structure and the fundamental chemical reactions of the lithium battery. Secondly, the study states that differences of discharge curves led by different materials. Through various discharge curves of the lithium batteries that to create model of lithium battery. Lastly, we may know charateristics by parameter in lithium battery.
This thesis contains significant contributions to the knowledge of LiPF6 and PVDF with different concentrations. The experiments were designed to LiPF6 and PVDF with different concentrations, and the shapes of discharge curves that to revise the parameters of models,.
Keywords：lithium batteries 、LiPF6、PVDF、 materials
