In this work we study the effect of the addition of lithium salts to light-emitting electrochemical cells (LECs), and in particular the effect of the lithium counterion. We found that the chosen lithium salts can substantially improve the device turn-on time as well as the overall lifetime, with respect to reference LECs using the pure emitter. A correlation between the lithium counterion and the corresponding device performance is established, and efficient LECs with lifetimes approaching 2000 hours are presented.
