From: Dendrite Suppression by Shock Electrodeposition in Charged Porous Media

Voltammetry of positively and negatively modified cellulose nitrate (CN) membranes of exposed area 1.327 cm2 between Cu electrodes in (a) 10 mM CuSO4 at 1 mV/s and (b) 100 mM CuSO4 at 10 mV/s. (c) Physical pictures of the effect of surface conduction on electrodeposition in a charged random porous media, driven by large electric fields in the ion depletion region.
