Despite the long history of the development of electrochromism, there are still no generally accepted methods for a quantitative comparison of the cycling stability between different electrochromic materials or devices. By proposing a straightforward three-step procedure, we report a simple set of parameters that describe the cycling stability performance of some of the most frequently used electrochromic materials, namely conducting polymers, transition metal oxides, metallo-supramolecular polymers and viologens. The main features of this procedure are an adequate definition of the testing conditions and the analytical description of the materials performance evolution through continuous cycling. The resulting parameters not only allow us to perform comparative studies among different materials and devices, but to identify tendencies, and therefore establish the corresponding balance, between the testing conditions and the cycling stability/optical performance obtained. This method constitutes a powerful decision-making tool for the academic and the industry-related electrochromic community.Read less <
