Recently, as the demand for secondary batteries for electric vehicles has rapidly increased, the efficient production of lithium compounds is attracting great attention. Bipolar membrane electrodialysis (BPED) is known as an eco-friendly, economical, and efficient electrochemical lithium compound production process. Since the efficiency of the BPED depends on the performance of the bipolar membrane (BPM), the selection of the BPM is very important. In this study, the characteristics of BPMs suitable for the BPED for electrochemical LiOH production were derived by comparative analyses of BP-1E (Astom) and FBM (Fumatech), which are the most widely used commercial BPMs in the world. Through systematical evaluation, it was confirmed that reducing membrane ion transfer resistance and co-ion leakage among the characteristics of BPM is the most important, and BP-1E has better performance than FBM in this respect.

본 연구에서는 배위자로 공액계 벤젠고리로 연결된 중심금속이 이리듐인 착물화합물과 합성하여 인광재료로서의 가능성을 실험하였다. 새로운 이리듐착물화합물의 화학적 구조를 알아보기 위해 $^1H$-NMR, $^{13}C$-NMR, UV-vis, spectrophotometer를 사용하였으며, 광 물리학적, 전기화학적 특성에 대한 측정은 spectrofluorometer, cyclic voltammetry를 통하여 측정하였다. 이리듐 단핵 및 이핵착체는 589~598nm의 영역에서 발광파장이 확인되었으며, DMSO[$5{\times}10^{-5}$]용액에서 양자효율이 단핵 착물화합물의 경우 0.1, 이핵착물화합물의 경우 0.13으로 나타났다. 이핵 이리듐착물화합물의 전기화학적 특성은 energy gap은 2.45eV, optical band gap은 2.58eV로 계산되었다.
