Abstract

In order to investigate the electrochemical properties and the particle size effect of $LiNi_{1-x-y}Co_xAl_yO_2$ (x=0.15, y=0.045 or 0.05, NCA) for lithium ion batteries (LIBs), two commercial NCA cathode materials (NCA#1, NCA#2) were used as cathode materials for LIB. The average particle size of the NCA#1 which consisted of uniform spherical particles was found to be approximately $5m{\mu}$. NCA#2 consisted of particles with bimodal size distribution of approximately $5m{\mu}$ and $11m{\mu}$. From the results of charge-discharge performance test, a high initial discharge capacity of 197.0 mAh/g was obtained with NCA#2, which is a higher value than that with NCA#1. The cycle retentions of NCA#1 and NCA#2 up to 30 cycles were 92% and 94%, respectively.

$LiNi_{1-x-y}Co_xAl_yO_2$(x=0.15, y=0.045 혹은 0.05, NCA) 양극소재의 전기화학적 특성 및 양극소재의 입자 크기 분포에 대한 리튬이온이차전지의 수명특성에 대한 영향을 살피기 위해 두 종의 상업용 NCA (NCA#1, NCA#2) 양극소재를 리튬이온이차전지의양극으로사용하였다. NCA#1은약 $5m{\mu}$의 균일한구형의입자로구성되어있고 NCA#2는약 $5m{\mu}$와 $11m{\mu}$ 정도의 입자들이 혼합되어 있는 분말이다. 충방전 측정 결과 NCA#2는 초기 방전용량은 197.0 mAh/g으로 NCA#1에 비해 높게 나타났다. NCA#1과 NCA#2의 용량 유지율(30 사이클 기준)은 각각 92%와 94%로 나타났다.
