제목 니켈계 층상구조 양극활물질의 열적 안정성에 관한 연구
초록 The thermal stability of the cathode materials is one of the key issues of the safety characteristics, which is related to the occurrence of exothermic reactions in charged batteries at elevated temperatures that can result in thermal runaway and catastrophic failure of the battery. Therefore, in-depth understanding of the structural changes of the charged cathode material during thermal decomposition is very important. New findings of the unique phase transition behaviors of the charged Li1-xNi1/3Co1/3Mn1/3O2 cathode during thermal decomposition will be presented in comparison with Li1-xNi0.8Co0.15Al0.05O2 cathode materials.
