Abstract

Multi-layer electrochromic structures, and processes for assembling such structures, incorporating a cross-linked ion conducting polymer layer that maintains high adhesive and cohesive strength in combination with high ionic conductivity for an extended period of time, the ion conducting polymer layer characterized by electrochemical stability at voltages between about 1.3 V and about 4.4 V relative to lithium, lithium ion conductivity of at least about 10−5 s/cm, and lap shear strength of at least 100 kPa, as measured at 1.27 mm/min in accordance with ASTM International standard D1002 or D3163.
