Graphite is a widely used anode electrode material for Li-ion batteries. When the anode is polarized to a low potential, the electrolyte reduction products form a film called SEI (Solid Electrolyte Interphase) playing a crucial role in the reversibil

Microelectrode steady-state voltammetry is used to monitor on-line the progress of preparative electrolyses. This allows to follow educt and product concentrations as a function of the advance of the electrolysis, end-point detection, calculation of
