Abstract:
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.
