Violet tungsten oxide can serve as a cathode electrochromic material – one of electrochromic materials. The other type is an anode electrochromic material. When the electrochromic material is at the cathode and is colored, it is called cathodic coloring, and its electrochemical reaction formula is: More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Moy + xA+ + xe- ? AxMOy (0≤x≤1) Where, MOy is a metal oxide (colorless), the metal has a higher oxidation state; A+ is an injected small positive ion such…
