Abstract
High performance electrodes for electrochemical devices having a polymer network with an electroactive material chemically attached to a crosslinked polymer matrix are disclosed. A method includes mixing an electrode slurry and forming a polymer network within the electrode slurry. The electrode slurry includes an electroactive material, an electrically conductive filler, a plurality of polymer chains, and a plurality of chemical crosslinking precursors. Each chemically crosslinking precursor is configured to (i) chemically crosslink the plurality of polymer chains and (ii) chemically attach the electroactive material to the plurality of polymer chains.
