Abstract/Summary:
The inhibition of passivation of lithium electrode by self-assembled molecular layers (SAMs) at the lithium electrode/polymer electrolyte interface has been studied under open circuit and cycling conditions. The effectiveness of SAMs under cycling conditions has been evaluated under cycling conditions. AC impedance data have been analyzed by equivalent circuit analysis to observe the growth of the passivation layer. Application of the microelectrode array theory to the passivated lithium surface, together with the equivalent circuit analysis, has provided valuable insights into the performance of SAMs and their stability. Cyclic voltammetric studies have been carried out to characterize the effect of SAMs on the nature of electrode reactions. Effects of SAMs that lead to passivation inhibition have been proposed. Finally, it has been demonstrated that Electrochemical Atomic Force Microscopy can be used for atomic scale electrochemical measurements.
