Abstract
Li-ion cells employ lithium transtion metal oxide as the cathode material and carbon as anode material. To manufacture Li-ion cell with higher capacity and better cycle life, the utilization of electrode materials should be as high as possible without lithium deposition onto the carbon surface during charging. A careful design of cell balance between cathode and anode materials as well as a proper charge method is a key factor to design Li-ion cell with long cycle life. In this study, we investigated the effect of cathode/anode weight ratio on the performance of
Li-ion 2차전지는 정극재료로 리튬전이금속산화물을, 부극재료로 탄소를 사용한다. 고용량 및 장수명을 지닌 Li-ion 2차 전지를 제작하기 위하여, 충전중에 탄소표면에 리튬 석출이 없이 전극 활물질의 이용율은 가능한 높아야 한다. 정극 및 부극 재료의 balance 및 적절한 충전 방식이 Li-ion 2차전지의 설계에 있어서 중요한 요소이다. 본 연구에서는
