The EDS analysis and the morphology observation indicate that the complexes of zinc, Zn(NH3)2Cl2, most probably present in spent batteries; the microporous structure of the positive electrode materials facilitates the diffusion of the electrolyte to inner regions of the electrode; zinc in negative electrode converts in the ionic form, then zinc ions and graphite transfer to the positive electrode through the micropores along with electrolyte during the discharging of the batteries.
