A bipolar capacitor-assisted solid-state battery is disclosed that includes a plurality of electrochemical battery unit cells, each of which includes a negative electrode, a positive electrode, and a lithium ion-conductive electrolyte-containing separator disposed between the negative electrode and the positive electrode. The lithium ion-conductive electrolyte-containing separator of each electrochemical battery unit cell comprises a solid-state electrolyte material, and, additionally, at least one negative electrode of the electrochemical battery unit cells or at least one positive electrode of the electrochemical battery unit cells includes a capacitor material. The bipolar capacitor-assisted solid-state battery further includes a bipolar current collector disposed between a negative electrode of one electrochemical battery unit cell and a positive electrode of an adjacent electrochemical battery unit cell. A method for manufacturing the disclosed bipolar capacitor-assisted solid-state battery is also disclosed.
