Yellow tungsten oxide can be used to study and produce a new electrochromic device. So, what indicators can be used to evaluate the performance of the prepared electrochromic device?

One of the important indicators for evaluating the performance of electrochromic devices is response time. The response time refers to the time required for the electrochromic device to switch from one state (colored state or bleached state) to another state, and may also be referred to as the time required for ion injection and extraction. It is determined by the dispersion coefficient of ions and the length of the dispersion path. The former mainly depends on the chemical structure and crystal structure of the electrochromic material; the latter depends mainly on the microstructure and morphology of the electrochromic material. The response time of electrochromism can be divided into coloring response time and bleaching response time, which refer to the time required for the device to switch from a fully bleached state (or fully colored state) to a certain colored state (or bleached state).
