Abstract
The present invention provides A method for preparing an electrode containing lithium nickel oxide wherein nickel has a single oxidation number, which comprises the following steps: a) preparing an electrode containing the lithium nickel oxide (LixNi1−yO, 0.4<x<1, 0<y<1) layer formed on the conductive substrate; and b) applying oxidative voltage to the electrode, and then applying reductive voltage thereto, an electrode prepared by the method and an electrochromic device containing the same.The electrode containing the lithium nickel oxide layer of the present invention exhibits wider optical electrochromic range and fast reaction speed, so that it can contribute to improving electrochromism and other optical properties of an electrochromic device.
