    Abstract: Energy storage devices, battery cells, and batteries may include a first current collector having an anode active material disposed along a first surface of the first current collector. The cells may include a plurality of first electrodes positioned along a second surface of the first current collector opposite the first surface. The plurality of first electrodes may be characterized by a first orientation. The cells may include a second current collector having a cathode active material disposed along a first surface of the second current collector. The cells may include a separator positioned between the anode active material and the cathode active material. The cells may also include a plurality of second electrodes positioned along a second surface of the second current collector opposite the first surface. The plurality of second electrodes may be characterized by a second orientation substantially orthogonal to the first orientation.

    Abstract: Energy storage devices, battery cells, and batteries of the present technology may include a first battery cell. The first battery cell may include an anode current collector, and an anode active material disposed on the anode current collector. The first battery cell may include a cathode current collector and a cathode active material disposed on the cathode current collector. The current collectors may be polymeric materials. The batteries may include a first conductive band electrically coupled with the first battery cell. The first conductive band may be seated on the second surface of one of the anode current collector or the cathode current collector. The first conductive band may extend about a perimeter of the one of the anode current collector or the cathode current collector. The batteries may include a cell module including a first flexible extension electrically coupled with the first conductive band.

    Abstract: Battery packs are presented having structural members for improving thermal management of battery cells therein. In some embodiments, the battery packs include a first end-member positioned opposite a second end-member and parallel thereto. The battery packs also include a first side beam positioned opposite a second side beam and parallel thereto. The first side beam and the second side beam extend longitudinally between the first end-member and the second end-member. A longitudinal member is disposed between the first side beam and the second side beam and defines a plurality of longitudinal rows. The battery packs may additionally include a lateral member disposed between first end-member and the second end-member to partition the plurality of longitudinal rows into an array of battery cell compartments. A battery cell is disposed within at least one battery cell compartment.
