기능성 이온 단량체의 가교를 통하여 표면 개질된 고율 충전용 리튬 망간 산화물 양극 소재

다국어 초록 (Multilingual Abstract)

In this study, 3-propyl-1-vinylimidazolium tetrafluoroborate (VPI BF₄) as an ionic crosslinker is designed and synthesized to improve the high rate capability of lithium manganese oxide (LMO) cathode material. The synthesis of ionic crosslinker is confirmed by ¹H nuclear magnectic resonance and <SUP>19</SUP>F nuclear magnectic resonance spectroscopies. It is confirmed that the VPI BF₄ is successfully crosslinked through Fourier-transform infrared spectroscopy. The use of VPI BF₄ does not compromise with the electrochemical performance of the cell even at high temperature and enhances the rate capability. The analysis of electrodes after electrochemical evaluation proves that VPI BF₄ contributes to the improvement of LMO interphase properties.
