Paper Abstract

Studies of the electrochromic properties of nickel hydroxide and related nickel oxide materials have revealed promising characteristics for smart window applications including a high coloration efficiency throughout the visible region' 8. In addition, good durability in electrochromic switching (over 5000 coloration/bleaching cycles with no significant degradation in response) has been reported for sputtered nickel oxide films7. However, there have also been some unfavorable reports about the durability of electrochromic nickel hydroxide films3'5'8. For example, a significant deterioration in the electrochromic response of cathodically deposited nickel hydroxide films has been observed in less than 500 cycles3. Estimates of the number of coloration/bleaching cycles needed for automotive smart window applications are in the range of 105 cycles--enough to allow switching once per mile during a 100,000 mile car lifetime.
