More Information
Summary:Electrodeposited copper foils having properties suitable for use as current collectors in lithium-ion secondary batteries are disclosed. The electrodeposited copper foils include a drum side and a deposited side. At least one of the deposited side or the drum side exhibits a void volume (Vv) value in the range of 0.17 to 1.17 μm^3/μm^2. 리튬-이온 2차 배터리에서 집전 장치로서 사용하기에 적합한 특성을 갖는 전착된 구리 호일이 보고되어 있다. 전착된 구리 호일은 드럼 측면 및 증착된 측면을 포함한다. 증착된 측면 또는 드럼 측면 중의 적어도 하나는 0.17 내지 1.17 μm/μm의 공극 용적(Vv) 값을 나타낸다.
