제목 Cycle Performance Improvement of LiFePO4 Cathode with arious Nano Carbon Materials as Electronic Conducting Agent
초록 Lithium iron phosphate has a special structure, extraordinary theoretical capacity and high thermal stability. However, it has lower operating voltage than other lithium ion batteries relatively. In addition. the electrical conductivity is very low. Thus, many research groups has studied constantly to overcome this bottleneck. In this study, cathode active material was synthesized by using high-temperature solid-phase method. Resulting products were analyzed by SEM and XRD. Cell was fabricated by using graphene and carbon black as a electronic conducting agent. Eelectrical characteristics were evaluated by charg-discharge testing system.
