Reversible electrochemical conversion from selenium to cuprous selenide
Using elemental selenium as an electrode, the redox-active Cu 2+ /Cu + ion is reversibly hosted via the sequential conversion reactions of Se → CuSe → Cu 3 Se 2 → Cu 2 Se. The four-electron redox process from Se to Cu 2 Se produces a high initial specific capacity of 1233 mA h g −1 based on the mass...
