Abstract: Provided herein are systems, apparatuses, and methods of providing electrical energy for electric vehicles. A battery pack can be disposed in an electric vehicle to power the electric vehicle. A battery cell can be arranged in the battery pack. The battery cell can have a housing. The housing can define a cavity within the housing. The battery cell can have an electrode structure arranged within the cavity. The electrode structure can include a first polarity electrode plate, a second polarity electrode plate, and at least one separator. First and second polarity tabs are coupled with the first and second polarity electrode plates, respectively. The tabs include a flat surface, an electrode interface surface and at least one intermediate surface that extends therebetween. The at least one intermediate surface forms an acute angle with the electrode interface surface.

Abstract: A process for producing a corrugated electrode for use in an electroactive polymer cartridge is disclosed. A laminated web comprising a support sheet laminated to a dielectric elastomer film is positioned. The support sheet defines areas exposing portions of the dielectric elastomer film. A force is applied to the positioned laminated web to stretch the laminated support sheet-dielectric elastomer film web in a direction that is orthogonal to a plane defined by the web. An electrically conductive material is applied to the laminated support sheet-dielectric elastomer film web while the laminated support sheet-dielectric elastomer film web is in a stretched state. The laminated support sheet-dielectric elastomer film web is relaxed to form the corrugated electrode on the dielectric elastomer film portion of the web.
