초록
2차 전지의 양극(anode)으로 사용되는 Li-AGICs를 혼합가압법에 의하여 Li의 함유량에 따라 합성하였다. 이들 합성된 화합물을 X-선회절법, UV/VIS 분광학적 분석법 및 DSC 열분석법을 이용하여 특성화하였다. X-선회절분석 결과에 의하면 리튬의 함유량이 증가함에 따라 낮은 stage가 관찰되었으나, 각각의 화합물들은 혼재된 stage를 가지고 있음이 나타났다.
Li-AGICs as a anode of secondary battery were synthesized by high-pressure method as a function of the Li-contents. The characteristics of these prepared compounds were determined from the studies with X-ray diffraction method, UV/VIS spectrophotometric and differential scanning calorimeter(DSC) analysis. From the results of X-ray diffraction, it was found that the lower stage intercalation compounds were formed with increase of Li-contents. The mixed stages in these compounds were also observed. In the case of the
