In article number 1600651, Keun Hyung Lee, Jong‐Lam Lee, and co‐workers describe a switchable dual‐function electronic device that can store electric charges and emit photons with λ = 620 nm using ionic liquid based polymer gel electrolytes, ion gels. A sandwich‐type device performs energy storage function through pseudo‐capacitive charge transfer reactions in a DC operation mode and the same device radiates light through electrochemiluminescent redox reactions under an AC condition.
