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: 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: An enclosure for a portable computing device is disclosed. The enclosure includes an indicium (e.g., logo) positioned in an opening extending partially through the enclosure. The enclosure includes multiple material removal processes. First, a tool (e.g., laser ablation tool) can be used to ablate the opening defining an ablation having a shape or profile similar to that of the indicium. A second material removal process can remove a region within the ablation to define an indicium support. The second material removal process may be performed by a CNC cutting tool capable of forming the indicium support to a desired precision. As a result, when the indicium is secured with the indicium support, the indicium includes a desired flatness that prevents an undesired reflectivity. In order to ensure the indicium properly fits in the opening, a third material removal process may be performed to define an indention region around the opening.
