▎ 摘　　要

NOVELTY - Manufacture of electrochromic device (100) involves growing a graphene on a growth substrate, performing an atomic layer deposition process on the graphene layer (120), forming an atomic layer (130), forming a transparent conductive layer (140) on the atomic layer, forming an electrochromic layer (153), an electrolyte layer (152), and an ion-storage layer (151) sequentially on the layer (140), and forming a transparent conductive layer (160) on the electrochromic layer. USE - Manufacture of electrochromic device (claimed) used as smart window, room mirror, and sun visor of motor vehicle. ADVANTAGE - The method enables efficient manufacture of electrochromic device with excellent transparency and flexibility, and suppressed generation of defects with respect to graphene layer having excellent electroconductivity and high quality, by fast and economical process. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view explaining manufacture of electrochromic device.
