【 摘 要 】

In this study a composite observed in PVDF composite as lithium ion battery separator. Observation of performance cell battery with cyclic voltametry and charge discharge capacity. Surface morphology PVDF separator and commercial separator observed with Scanning electron microscopy (SEM). Cyclic Voltamerty test (CV) and Charge Discharge (CD) showed a capacity value on the coin cell. Coin cell is composed of material LiFePO4cathode, anode material of lithium metal and varies as graphite, liquid electrolyte varied use LiBOB and LiPF6. While the PVDF as compared to the commercial separator. Coin cell commercial separator has a better high capacity value when compared with Coin cell with the PVDF separator. Life cycle coin cell with the commercial separator material is still longer than coin cell separator with PVDF Copolymer. Development of PVDF as separator remains to be done in order to improve the performance of the battery exceeds the usage of commercial material.
