Discharge process (Zn dissolution from the porous half-cell) followed by the XAFS spectral features (a) shoulder height (metallic phase) and main peak area (Zn-chelate aqueous phase); and (b) Zn fraction in the cell semi-quantified by least-squares linear combination fitting of the XANES spectra using metallic Zn and Zn-malonate solution references. |
