Stor.. 2016;13(3):031006-031006-13. doi:10.1115/1.4035198 Figure Legend: (a) Schematic representation of a Li-ion battery half cell. Half cells are prepared with lithium counter electrode and test electrode to characterize electrochemical performance of the electrode under investigation and (b) a pore-scale view of local arrangement of different phases in composite Li-ion battery electrode. The electrochemical reaction—intercalation takes place at active material–electrolyte interface. This interfacial area gets covered due to the addition of electrochemically inactive species like conductive additive and binder, which are quite essential for overall cell performance and stability. Active material irreversibly reacts with electrolyte to form solid electrolyte interphase (SEI), which is not shown on the figure.
