摘要： The presently disclosed concepts relate to improved techniques for critical mineral extraction, purification, precipitation, ion exchange, and metal production using a solid electrolyte membrane. By using a solid electrolyte embedded in a matrix, alkali metal (such as lithium) can be more effectively separated from feed solutions. Additionally, energy used to initially extract critical minerals from a feed solution may be stored as electrochemical energy, which in turn, may be discharged when critical minerals are depleted from the electrode. This discharged energy may therefore be reclaimed and reused to extract additional critical minerals.

摘要： A lithium-sulfur battery may include a cathode, an anode structure positioned opposite to the cathode, a separator, and an electrolyte. In some instances, the anode structure may include an artificial solid-electrolyte interphase (A-SEI) that may form on and within the anode structure. A protective layer may form within and on the A-SEI, and may include exposed carbon surfaces formed by coalescence of several wrinkled graphene nanoplatelets with one another. Metal-containing substances may be decorated on and/or attached with at least some exposed carbon surfaces and regulate flow of lithium (Li+) cations within the lithium-sulfur battery and correspondingly moderate one or more of a plating rate or a de-plating rate of lithium onto the anode structure. The separator may be positioned between the anode structure and the cathode. The electrolyte may be dispersed throughout the cathode and in contact with the anode structure.

摘要： A lithium-sulfur cylindrical cell. The cell includes a cylindrical shell defining an inner volume, and a jelly roll disposed within the inner volume. The jelly roll includes an anode comprising lithium, where the anode is configured as a freestanding assembly. Additionally, the jelly roll comprises a cathode comprising sulfur. Further, the jelly roll comprises a first separator between a first side of the anode and a first side of the cathode. In cylindrical cell formats, the jelly roll comprises a windable second separator. As the jelly roll is wound, the second separator may come in direct contact with both a second side of the anode and with a second side of the cathode. Alternatively, as the jelly roll is wound, the second separator may come in direct contact with the second side of the anode and with a cathode current collector.

摘要： The presently disclosed concepts relate to ultra-efficient EV battery recycling systems. Alkali metal extraction (and in particular lithium extraction) is accomplished using a solid electrolyte membrane. By using a solid electrolyte embedded in a matrix, alkali metals, in particular lithium can be (energy-wise) efficiently separated from feed solutions. The energy used to initially extract lithium from a feed solution is stored as electrochemical energy, which electrochemical energy is reclaimed in subsequent extraction processing steps. This energy storage and energy reclamation is performed in continuous ultra-efficient ongoing cycles. Since irrecoverable energy losses incurred in each cycle are limited to negligible amounts of joule heating of the system components and feed solution, the system can be sustainably powered using locally-generated renewable energy.

摘要： This disclosure provides a battery including a cathode, an anode positioned opposite the cathode and a carbon interface layer. 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.

摘要： 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.

摘要： A lithium-sulfur battery including an anode structure, a cathode, a separator, and an electrolyte is provided. A protective layer may form within the anode structure responsive to operational discharge-charge cycling of the lithium-sulfur battery. The protective layer may include a polymeric backbone chain formed of interconnected carbon atoms collectively defining a segmental motion of the protective layer. Additional polymeric chains may be cross-linked to one another and at least some carbon atoms of the polymeric backbone chain. Each additional polymeric chain may be formed of interconnected monomer units. A plasticizer may be dispersed throughout the protective layer without covalently bonding to the polymeric backbone chain. The plasticizer may separate adjacent monomer units of at least some additional polymeric chains. Increasing separation of adjacent monomer units increases a cooperative segmental mobility of the additional polymeric chains and ionic conductivity of the protective layer.

摘要： 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.
