Abstract: Systems, methods, and devices for gas management of metal-air batteries. Each one of a plurality of electrochemical cells may include at least one air electrode, a metal electrode, a vessel, and a liquid electrolyte between the at least one air electrode and the metal electrode in the vessel, with each one of the plurality of electrochemical cells defining a respective headspace above the liquid electrolyte in the vessel. A manifold may include ducting defining a shared vent and an outlet region, and the respective headspace of each one of the plurality of electrochemical cells may be fluidically coupled to the shared vent and in fluid communication with the outlet region of the ducting.

Abstract: According to an aspect, an electrochemical cell may include a vessel, at least two instances of an anode assembly, at least two instances of an oxygen evolution electrode (OEE), and a gas diffusion electrode (GDE). In the vessel, the GDE may be disposed between mirrored arrangements of the at least two instances of the OEE and the at least two instances of the anode assembly.

Abstract: According to one aspect, a power storage system may include an enclosure, and one or more modules disposed in the enclosure. Each of the one or more modules may include a plurality of electrochemical cells electrically coupled to one another, each one of the plurality of electrochemical cells including an oxygen evolution electrode (OEE), an anode, a gas diffusion electrode (GDE), an electrolyte, and a vessel and, within the vessel, the OEE, the anode, and the GDE at least partially immersed in the electrolyte.

Abstract: Systems, methods, and devices of the various embodiments may include battery string arrangements for power systems, such as dynamic battery string configurations, inter-module connections, and other configurations.

Abstract: Systems and methods of the various embodiments may provide bifacial sealed gas diffusion electrode (GDE) assemblies. In some embodiments, a bifacial sealed gas diffusion electrode (GDE) assembly includes active electrode layers on two opposing sides of the assembly. Various embodiments may provide architecture and/or sealing methods for GDE assemblies. In various embodiments, the GDE assemblies may be for use in devices. In various embodiments, the devices may be primary or secondary batteries. In various embodiments, these devices may be useful for energy storage. For example, bifacial sealed GDE assemblies of the various embodiments may form cathode electrodes (sometimes called air electrodes) of a battery, such as a metal-air battery.

Abstract: A solar energy collection system can include improved mounting hardware for reducing hardware costs and labor required for assembly. For example, mounting hardware can include surfaces for supporting part or all of the weight of a solar module as it is brought into contact with mounting hardware and then moved into a final engaged position. In some systems, a torque tube can include saddle mount assemblies that allow a solar module to be partially engaged and a registered with the saddle mount while being pivoted into a final locked engagement. Some systems can include arrangements sufficient to support the full weight of a solar module in a disengaged position, and as it is moved into a final engaged position. Some systems can include a configuration of apertures and interference or snap-fit features for providing tool-less connections, thereby simplifying the assembly process.
