Abstract: In some implementations, a metal air battery includes an anode and an 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 carbon interface layer includes an electrically insulating flaky carbon layer conformally encapsulating the anode. A plurality of carbon nano-onions (CNOs) defining a plurality of interstitial pore volumes are interspersed throughout the electrically insulating flaky carbon layer. An electrolyte is in contact with the carbon interface layer and the cathode. A separator is positioned between the anode and the cathode. The electrically insulating flaky carbon layer can include graphene oxide (GO). The plurality of interstitial pore volumes can be configured to transport lithium (Li) ions between the anode and the cathode via the plurality of interstitial pore volumes in a bulk phase of the electrolyte. The carbon interface layer can be configured to inhibit growth of Li dendritic structures from the anode towards the cathode.

Abstract: A composition of matter may include pores and non-tri-zone particles and tri-zone particles. In one implementation, each tri-zone particle may include carbon fragments intertwined with each other and separated from one another by mesopores. Each tri-zone particle may also include a deformable perimeter that may coalesce with adjacent non-tri-zone particles or tri-zone particles. In some aspects, the tri-zone particles may include aggregates formed by a multitude of the tri-zone particles joined together. In some aspects, mesopores may be interspersed throughout the aggregates. Each tri-zone particle may also include agglomerates, where each agglomerate includes a multitude of the aggregates joined together. In some aspects, macropores may be interspersed throughout the aggregates.

Abstract: A battery is disclosed that includes an anode, a cathode positioned opposite to the anode, a protective sheath disposed on the cathode, a separator, and an electrolyte. The anode may be arranged in a lattice configuration and include carbonaceous materials. The separator may be disposed between the anode and cathode. The protective sheath may include a tri-functional epoxy compound and a di-amine oligomer-based compound that can chemically react with each other. In this way, the protective sheath may prevent polysulfide migration within the battery based on chemical binding between the protective sheath and one or more lithium-containing polysulfide intermediates. The electrolyte may disperse within the cathode and contact the anode. In one implementation, a polymeric network may be deposited over one or more exposed surfaces of the anode. The polymeric network may have fluorinated polymer chains grafted with carbonaceous materials and be cross-linked with each another.

Abstract: A battery is disclosed that includes an anode, a graded interface layer disposed on the anode, a cathode positioned opposite to the anode, an electrolyte, and a separator. The anode may output lithium ions during cycling of the battery. A graded interface layer may be disposed on the anode and include a tin fluoride layer. A tin-lithium alloy region may form between the tin fluoride layer and the anode. The tin-lithium alloy region may produce a lithium fluoride uniformly dispersed between the anode and the tin fluoride layer during operational cycling of the battery. The electrolyte may disperse throughout the cathode and the anode. The separator may be positioned between the anode and cathode. In some aspects, the battery may also include lithium electrodeposited on one or more exposed surfaces of the anode.
