Abstract: In some implementations, a metal air battery includes an anode and a cathode opposite to the anode. The cathode may be formed as a textured carbon-based scaffold and include an opening into the metal air battery. The metal air battery may include a nano-fibrous membrane (NFM) containing a liquid electrolyte and a functionalized carbon structure may be disposed between the cathode and the NFM. The functionalized carbon structure may allow moisture and oxygen from ambient air to permeate through the NFM and diffuse throughout the textured scaffold of the cathode. A moisture barrier layer may be laminated over the cathode and positioned, by a user, in one of two states. When in a first state, the moisture barrier layer may seal the opening. When in a second state, the moisture barrier layer may allow the moisture and the oxygen to enter the textured scaffold.

The cathode may be a carbon-based textured scaffold including a plurality of macroporous pathways to distribute oxygen and water vapor supplied by ambient air throughout the cathode and into interior portions of the body. The NFM may include dry salts to produce a liquid electrolyte when exposed to water vapor delivered by the macroporous pathways of the cathode. The hygroscopic interphase layer may include a plurality of microporous pathways configured to drain excess quantities of the water vapor from the cathode and hydrate the dry salts with the water vapor.

Abstract: A lithium-sulfur battery including an anode, a cathode, a separator, and an electrolyte dispersed throughout the lithium-sulfur battery is provided. The anode may output lithium ions. The cathode may be positioned opposite to the anode and have an overall porosity as defined by multiple non-hollow carbon spherical (NHCS) particles joined together to form tubular NHCS particle agglomerate. Pores may be associated with the overall porosity of the cathode and interspersed uniformly throughout the NHCS particles. In some aspects, each pore having a diameter between 1 nm and 10 nm; and each tubular NCHS agglomerate has a length between 5 micrometers (μm) and 35 μm. Interconnected channels defined in shape by the NHCS particles may be joined to each other and the pores, where some interconnected channels may be pre-loaded with an elemental sulfur and retain polysulfides (PS). Retention of the polysulfides may be based on some NHCS particles.

Abstract: A composition of matter suitable for incorporation into a battery electrode is disclosed. In some implementations, the composition of matter may include pores that may be defined in size or shape by several carbonaceous particles. Each of the particles may have multiple regions such that adjacent regions are separated from each other by some of the pores. Deformable regions may be distributed throughout a perimeter of each of the particles, for example, to accommodate coalescence of multiple adjacent particles. The composition of matter may also include a plurality of aggregates and a plurality of agglomerates, where each aggregate includes a multitude of the particles joined together, and each agglomerate includes a multitude of the aggregates joined together.
