Electrochromic tungsten oxide films for energy efficient windows

In this paper a brief survey is given of the properties of non-aqueous electrolyte solutions and their applications in chemistry and technology without going into the details of theory. Specific solvent-solute interactions and the role of the solvent beyond its function as a homogenous isotropic medium are stressed. Taking into account Parker's statement1) “Scientists nowadays are under increasing pressure to consider the relevance of their research, and rightly so” we have included examples showing the increasing industrial interest in non-aqueous electrolyte solutions.

Non-aqueous electrolyte solutions in chemistry and modern technology

The electrochromic behavior of has been studied by potentiostatic and galvanostatic measurements for both symmetric and asymmetric cells. The kinetics of coloration and bleaching are ascribed to barrier‐limited and space charge‐limited current flow, respectively, similar to the case of . Galvanostatic measurements indicate linearity of optical density with injected charge at low injection levels. At high injection levels a nonlinear response is observed which is attributed to the approach of a phase boundary with increasing in . A general comparison of and in indicates greater stability for open‐circuit memory of the cells. Response times for various symmetric cells are tabulated.
