Electrochromic glazing

An electrochromic glazing comprising a glass sheet (1),

• a first transparent electroconductive electrode (2),
• a cathodic electrochromatic material layer (4),
• an electrolyte (5) selected from the group consisting of protonic and lithium conducting,
• an anodic electrochromatic material layer (6) and a second transparent electroconductive electrode (8),
• the first electrode (2) comprising a barrier layer (3) of tin oxide in contact with the cathodic electrochromic material layer (4) and the second electrode comprising a barrier layer (7) of tin oxide in contact with the anodic electrochromic material layer (6),
• wherein said anodic electrochromic material layer is iridium oxide when said electrolyte is protonic,
• and said anodic electrochromic material layer is nickel oxide when said electrolyte is lithium conducting,
• wherein said first and second electrodes comprise an indium tin oxide layer.
