  • Publication number: 20220250914
    Abstract: A method of electrochemical exfoliation, may include: electrochemically exfoliating a parent material comprising coke, wherein the electrochemically exfoliating comprises introducing the parent material into a porous chamber, applying pressure to the porous chamber to thereby compress the parent material in the porous chamber, and applying a potential bias to the parent material while at least a portion of the parent material is in contact with an electrolyte solution to produce a mixture of exfoliated material and unexfoliated parent material, wherein the exfoliated material comprises exfoliated graphene; and separating at least a portion of the exfoliated material from the unexfoliated parent material.

  • Publication number: 20220069291
    Abstract: A composite material for use as an electrode of an electrochemical cell comprises: a matrix that is provided by matrix particles that comprise an electrode active material; and a conductive fraction that is both electronically-conductive and ionically-conductive, the conductive fraction being provided by conductive particles that are distributed among the matrix particles. The conductive particles comprise either a material that is both ionically- and electronically-conductive; or a mixture of ionically-conductive particles and electronically-conductive particles, the electronically-conductive particles having a sphericity of at least 0.6. The conductive particles have a D90 value that is at least 10% of the D50 value of the matrix particles.

  • Patent number: 11131823
    Abstract: A ground wire with optical fibers is disclosed. The ground wire includes twisted optical modules in the form of plastic tubes that accommodate freely placed optical fibers and water-blocking gel, wherein water-blocking tape applied to twisted optical modules, which are enclosed in a steel tube, coated with an aluminum sheath. The aluminum sheath is helically wrapped with lays of wire. The technical result is provided by increased air tightness of the optical core and permissible crushing stresses.
