    摘要： The present disclosure provides an electrode for use in an electrochemical cell that cycles lithium ions. The electrode has a thickness greater than or equal to about 50 micrometers to less than or equal to about 500 micrometers and includes an electroactive material, a polytetrafluoroethylene-based binder, and a porous crystalline material additive. For example, the electrode may include greater than or equal to about 0.01 wt. % to less than or equal to about 20 wt. % of the porous crystalline material additive, and greater than or equal to about 0.01 wt. % to less than or equal to about 20 wt. % of the polytetrafluoroethylene-based binder. The porous crystalline material additive is selected from the group consisting of: metal-organic frameworks (MOFs), covalent-organic frameworks (COFs), and combinations thereof.

    摘要： The present disclosure provides an electrode for an electrochemical cell. The electrode includes a polymer binder network and a plurality of electroactive material particles. The polymer binder network includes a plurality of fibers defining the polymer binder network. Each of the plurality of fibers includes a plurality of beads and a plurality of filaments. The plurality of filaments extends from at least a portion of the plurality of beads, respectively. The plurality of electroactive material particles is in voids of the polymer binder network. In certain aspects, the present disclosure provides a single- or double-sided electrode component including a current collector and the electrode.

    摘要： A capacitor-assisted electrode for an electrochemical cell that cycles lithium ions is provided. The capacitor-assisted electrode may include at least two electroactive materials disposed on one or more surfaces of a current collector. A first electroactive material of the at least two electroactive materials may have a first reversible specific capacity and forms a first electroactive material having a first press density. A second electroactive material of the at least two electroactive materials has a second reversible specific capacity and forms a second electroactive material having a second press density. The second reversible specific capacity may be different from the first reversible specific capacity. The second press density may be different from the first press density. One or more capacitor materials may be disposed on or intermingled with one or more of the at least two electroactive materials.
