Abstract

In order to solve the problems of durability and structural stability, electrochromic laminated glass was manufactured using high strength electrolyte. The electrochromic glass developed in this study used tungsten oxide as the discoloring layer and nickel oxide as the ion storage layer. And the electrolyte was developed by synthesizing a polymer chemical resin based on lithium ions. As a result of evaluation of bonding strength of electrochromic glass, it was analyzed that 2.04 times improvement compared to existing gel type electrolyte. The ion conductivity was 2.57 × 10-4 S/cm that performance similar to that of the gel electrolyte. The discoloration efficiency was 83.08 cm2/C, which was superior to gel electrolyte. As a result of the optical characteristic analysis, the change in solar transmittance was 53.1% and the visible light transmittance was 57.3%, indicating that it is effective to reduce building energy under domestic climate conditions where summer and winter are clear.
