Reversible electrochemical conversion from selenium to cuprous selenide
- Oregon State University, Corvallis, OR (United States)
Using elemental selenium as an electrode, the redox-active Cu2+/Cu+ ion is reversibly hosted via the sequential conversion reactions of Se → CuSe → Cu3Se2 → Cu2Se. Here, the four-electron redox process from Se to Cu2Se produces a high initial specific capacity of 1233 mA h g–1 based on the mass of selenium alone or 472 mA h g–1 based on the mass of Cu2Se, the fully discharged product.
