▎ 摘  要

NOVELTY - Composite electrode material comprises an open-shell donor-acceptor polymer comprising multiple alternating electron-rich and electron-deficient monomers bonded together via a conjugated backbone, where the open-shell donor-acceptor polymer includes unpaired electrons when the open-shell donor-acceptor polymer is in a ground state, and the conjugated backbone comprises a connection of pi-orbitals of the monomers in alternating single bonds and double-bonds that facilitates delocalization of the unpaired electrons; and a carbon-based compound. USE - Composite electrode material for use in supercapacitor (claimed). ADVANTAGE - The carbon-based compound of the composite electrode material provides porous, conductive scaffolds for the composite electrode material, resulting in electrodes scalable to microns-thick films with fast kinetics. The supercapacitor has longer cycle life than batteries, greatly reduces the replacement and maintenance costs of sensor networks. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: i. Supercapacitor, which comprises: an anode comprising a first composite material comprising an open-shell donor-acceptor polymer comprising multiple alternating electron-rich and electron-deficient monomers bonded together via a conjugated backbone, where: the open-shell donor-acceptor polymer includes unpaired electrons when the open-shell donor-acceptor polymer is in a ground state, and the conjugated backbone comprises a connection of pi-orbitals of the multiple monomers in alternating single bonds and double bonds that facilitates delocalization of the unpaired electrons; and a carbon-based compound; and ii. method for producing a composite electrode material, which involves: suspending a conductive foil in a solution containing a monomer solvent and a carbon-based solvent; applying a first voltage to the solution causing a reduced carbon-based compound to deposit on the conductive foil; and dynamically applying a range of voltages to the solution causing an open-shell donor-acceptor polymer to form on the deposited reduced carbon-based compound, where the formed open-shell donor-acceptor polymer comprises multiple alternating electron-rich and electron-deficient monomers bonded together via a conjugated backbone, where the open-shell donor-acceptor polymer includes unpaired electrons when the open-shell donor-acceptor polymer is in a ground state, and the conjugated backbone comprises a connection of pi-orbitals of the multiple monomers in alternating single bonds and double bonds that facilitates delocalization of the unpaired electrons.
