This invention relates to the field of energy storage devices, and especially electrochemical energy storage devices where an electroactive moiety is chemically attached to a conductive polymer In particular, the invention relates to the design and fabrication of electrodes for the use in electrochemical storage devices having an electrochemically active conjugate. The electrochemically active conjugate preferably has an electroactive moiety selected from electroactive metal center, an electroactive organic species, or an electroactive non-metal species. Depending on the selected electroactive moiety, it can be attached either directly or through an appropriate linker to the conductive polymer.
A lithium-ion electrochemical storage cell comprising a cathode, an anode, and an electrolyte solution, wherein either the anode, the cathode or both comprise a stable, electrochemically active conjugate, the stable, electrochemically active conjugate comprising:
An electrochemical storage cell comprising a cathode, an anode, and an electrolyte solution, wherein the electrochemical cell is a lithium-ion battery, wherein at least the cathode is composed of an electrochemically active conjugate comprising a conductive polymer formed as a polypyrrole, and an electrochemical moiety covalently linked to the polypyrrole, wherein the electrochemical moiety is an electroactive moiety that comprises an electroactive metal center consisting of ruthenium (Ru) coordinated with at least one bipyridine functionalized to form an amide bond with the polypyrrole and bound to a multidentate ligand, and wherein the electrochemically active conjugate is composed of Ru[bpy]2[bpyCONH]+2 - - - PPy] on carbon support to produce charge carriers.
