The Intercalation of Lithium in Nickel Oxide and Its Electrochromic Properties

Abstract

Under rigorously dry conditions, nickel oxide sputtered samples undergo a reversible lithium intercalation‐deintercalation process which is accompanied by a net electrochromic effect. The characteristics of the process have been studied by cyclic voltammetry and by optical transmittance. The use of lithium‐intercalated nickel oxide as a new type of counter‐electrode in electrochromic windows is also discussed.
