    Abstract: Batteries according to embodiments of the present technology may include a first battery cell including a first current collector. The batteries may include a second battery cell including a second current collector. The second battery cell may be vertically aligned with the first battery cell, and the second current collector may be positioned adjacent the first current collector. The first battery cell and the second battery cell may be electrically coupled together so the first battery cell and the second battery cell transfer current through the cells between the first current collector and the second current collector. The batteries may also include a patterned coupling material disposed between the first battery cell and the second battery cell and joining the first current collector with the second current collector.

    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: Electrolyte dispensing systems according to embodiments of the present technology may include a housing defining an internal volume. The housing may define an inlet and an outlet. The dispensing system may include an inlet roller positioned proximate the housing inlet. The inlet roller may be configured to provide a substantial seal at the housing inlet when a substrate is delivered into the housing. The dispensing system may include a delivery device positioned between the housing inlet and housing outlet. The delivery device may be configured to supply an electrolyte to the substrate delivered into the housing. The electrolyte dispensing system may also include an outlet roller positioned proximate the housing outlet. The outlet roller may be configured to provide a substantial seal at the housing outlet when the substrate is delivered from the housing.

    Abstract: Energy storage devices, battery cells, and batteries of the present technology may include a first current collector and a second current collector. At least one of the first current collector and the second current collector may be a non-metal current collector. The battery cell may include a seal between an edge region of the first current collector and an edge region of the second current collector. The seal may contact a first surface of the first current collector and a first surface of the second current collector. The battery cell may also include a metal material coupled with the non-metal current collector on a second surface of the non-metal current collector opposite the first surface.
