摘要 |
The present invention provides an electrode material comprising a combination of a compound having a disulfide group and a conductive polymer, or a conductive polymer having a disulfide group, wherein an S-S bond of the disulfide group is cleaved by the electrolytic reduction to form a sulfur-metal ion bond or a sulfur-proton bond, and the sulfur-metal ion bond or the sulfur-proton bond re-forms an S-S bond by the electrolytic oxidation. The present invention also provides a lithium rechargeable battery comprising a cathode, a solid electrolyte, and an anode, wherein the cathode is made of a composition containing as its main components lithium thiolate having a sulfur-lithium ion bond capable of forming a disulfide bond by the electrolytic oxidation and a pi electron conjugated conductive polymer; or a composition containing as its main component a pi electron conjugated conductive polymer having a sulfur-lithium ion bond capable of forming a disulfide bond by electrolytic oxidation; the solid electrolyte is a composition containing a salt containing lithium, or a polymer containing the salt; and the anode is made of a composition containing as its main components aluminium or an alloy containing aluminium, and carbon. |
