    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 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.

    Abstract: Battery housings and batteries are presented for accommodating swelling of an electrode assembly. In one aspect, a battery includes an electrode assembly that includes a cathode and an anode. The battery also includes a receptacle that includes at least one feedthrough disposed through one or more sides of the receptacle. A lid is sealed to the receptacle. The receptacle, the at least one feedthrough, and the lid form a sealed volume in which the electrode assembly and an electrolyte are disposed. The lid is configured to displace from a first position to a second position in response to a swelling of the electrode assembly within the sealed volume. The receptacle is configured to strain less than the lid during the swelling of the electrode assembly. The second position of the lid may correspond to an expanded volume of the electrode assembly that is 15% greater than an initial volume.
