| 제목 | High-throughput-screening of novel Cathode materials by Combinatorial Method |
| 초록 | LiCoO2 has a reasonable capacity and high safety performance. However, due to its toxicity and high cost, the research of other materials, like LiNiO2, and LiMn2O4, are risen for alternating the LiCoO2. But difficulty of synthesis in LiNiO2 and capacity fading in LiMn2O4 induced new type compoundLiCoO2-LiNiO2-LiMn2O4 combi-arrays. LiCoO2-LiNiO2-LiMn2O4 combi arrays are consistently deposited by co-sputtering system. So, we can obtain various compositions in the one Pt/TiO2/SiO2/Si wafer. With obtaining various compositions in lithium secondary thin film battery, we can find the composition which is behaved good performance and less reactive with electrolyte compare to LiCoO2. Thin films prepared by co-sputtering system and were investigated at various post annealing temperatures such as 600oC, 700oC, and 800oC. The thin films were analyzed by micro-beam XRD. And patterned Pt which was used current collector of cathode material was successfully fabricated by MEMS technique. The current collectors were consisted of 7×7 dots. So, we can realize high-throughput-screening of novel cathode materials. |
