The voltage between the two transparent conductive layers 117.

The ion storage layer 114 is adapted to store the ion M+ and the equilibrium charge e-, wherein, in the present embodiment, M+ represents hydrogen ion (H+), lithium ion (Li+) or sodium ion (Na+). The electrophoretic layer 115 provides a transport channel for the ions described above. In the present embodiment, the material of the electrochromic layer 116 is transparent tungsten trioxide (W0 ₃ ).
