Probing Electrochemical Potential Differences over the Solid/Liquid Interface in Li-Ion Battery Model Systems
The electrochemical potential difference (Δμ¯) is the driving force for the transfer of a charged species from one phase to another in a redox reaction. In Li-ion batteries (LIBs), Δμ¯ values for both electrons and Li-ions play an important role in the charge-transfer kinetics at the electrode/electrolyte interfaces. Because of the lack of suitable measurement techniques, little is known about how
