1. An electrochromic mirror assembly comprised of:
- a laminate structure;
wherein the laminate structure is substantially resistant to dendritic formation between adjacent layers of the laminate structure;
wherein the laminate structure includes;
first and second glass layers;
an electrochromic material layer disposed between the first and second glass layers;
a reflective layer adjacent to either of the first and second glass layers;
at least one spacer element disposed between the first and second glass layers, whereby the at least one spacer element prevents migration of the electrochromic material layer;
at least one electrically conductive layer disposed between the first and second glass layers; and
at least one adhesive layer;
wherein the at least one spacer element is disposed between the at least one adhesive layer and the at least one electrically conductive layer;
wherein the at least one adhesive layer does not abut the at least one electrically conductive layer.

Abstract
An electrochromic mirror assembly is described that is substantially resistant to seal breaches caused by dendrite formation along adjacent layers of the laminate structure of the assembly. The laminate structure is preferably assembled in a water free environment and includes materials that prevent or inhibit the formation of dendrites between adjacent layers of the laminate structure. By way of a non-limiting example, an electrically conductive layer comprised of gold-containing material is disposed between the adhesive layer and the glass layer so as to prevent ionic migration from the reflective layer through a terminal strip.
