| 제목 | A study on SnO2/LiPON/LiFePO4 structure all-solid-state lithium ion battery |
| 초록 | In this study, we prepared and characterized of thin-film batteries by DC(direct current) and RF(radio frequency) sputtering for all-solid-state lithium ion batteries. Ti and Cu thin films were deposited by DC sputtering for cathode and anode current collector. LiFePO4 thin film was deposited by RF sputtering for cathode. LiPON thin film was deposited by RF sputtering for electrolyte. SnO2 thin film was deposited by RF sputtering for anode. The surface morphologies and cross sectional view of thin films were characterized by FESEM(field-emission scanning electron microscopy). The structural properties of thin films were evaluated by XRD(X-ray diffraction). Ionic conductivity of LiPON thin film was evaluated by EIS(Electrochemical impedance spectroscopy). Ionic conductivity of LiPON thin film was 2.22 x 10-6 S/cm. Electrochemical properties of thin film battery were also characterized by galvanostatic system. Electrochemical test shows reasonable performance compare to those of bulk Li-ion batteries using LiFePO4 cathode, LiPON electrolyte, and SnO2 anode. It is expected to contribute to more reasonable batteries for micro devices. |
