Although LMB has a very large theoretical capacity, it has a critical problem such as formation of dentrite which causes short circuit and short cycle life of the LMB. In this study, PDMS/GO composite was synthesized and coated into a thin film, resulting in the effect that can physically suppress the formation of dendrite. However, PDMS has low ion conductivity, so that we attained improved ion conductivity of PDMS/GO thin film by forming the channel of Li ions. The morphology of the PDMS/GO thin film was observed to confirm using SEM. When the PDMS/GO thin film was utilized to lithium metal battery system, the columbic efficiency was maintained at 87.4% on average until the 100th cycles. In addition, volatge profiles indicate reduced overpotential in comparison to the electrode without thin film. |
