抄録

The electrochemical process of CuCl₂ supported on active carbon (AC) was analyzed by the XAFS measurements at the Cu K- and L-edge. It was clarified that a part of CuCl₂ was reduced to metallic Cu by the galvanic corrosion before the first discharge process. The XAFS analyses clarified that the remaining CuCl₂ was reduced during the discharge process up to 1.0 V vs. Li⁺/Li and that CuCl₂ was recovered by the charge process up to 4.5 V vs. Li⁺/Li. This study demonstrates the reversible redox reaction of CuCl₂/Cu pair on AC and its reasonable applicability to an active material of the chloride shuttle battery system.
