1. A process for preparing a multi-layer electrochromic structure, comprising:
- (a) depositing a film of a first liquid mixture onto a first substrate to form a first deposited film and treating the first deposited film to form a cathodic electrochromic layer comprising a first exposed surface and a first electrochromic state;
(b) depositing a film of a second liquid mixture onto a second substrate to form a second deposited film and treating the second deposited film to form an anodic electrochromic layer comprising an inorganic electrochromic material on the second substrate, wherein the anodic electrochromic layer comprises a second exposed surface and a second electrochemical state, the second electrochemical state being matched to the first electrochemical state; and
(c) forming a laminate of the anodic electrochromic layer, the cathodic electrochromic layer and a polymeric ion conductor layer, the polymeric ion conductor layer being sandwiched between the first exposed surface and the second exposed surface.

Abstract
Process for forming a multi-layer electrochromic structure, the process comprising depositing a film of a liquid mixture onto a surface of a substrate, and treating the deposited film to form an anodic electrochromic layer, the liquid mixture comprising a continuous phase and a dispersed phase, the dispersed phase comprising metal oxide particles, metal alkoxide particles, metal alkoxide oligomers, gels or particles, or a combination thereof having a number average size of at least 5 nm.
