The depletion of PMMA gel polymer electrode containing a binary electrolyte (cadmium perchlorate Cd(ClO4)2 in propylene carbonate PC) has been investigated. Impedance spectra were measured before and after recording a voltammogram of cadmium electrodeposition. The increase of electrolyte resistance, of polarisation resistance, and capacity component were evaluated. All these parameters indicate a strong depletion, which is known in Li polymer secondary cells, and which was lowered if a part of cadmium perchlorate was replaced by corresponding amount of LiClO4 as an indifferent electrolyte.
