KNa2CuO2 is a mixed-alkali copper oxide ceramic compound belonging to the family of layered cuprate materials. This material is primarily studied in research contexts for its potential in electronic and ionic conductor applications, particularly as a component in battery electrolytes, oxygen ion conductors, and solid-state electrochemical devices where the combination of potassium, sodium, and copper oxides may provide enhanced ionic mobility or catalytic properties compared to single-alkali alternatives.
