  • Patent number: 10044027
    Abstract: An object is to increase the conductivity of an electrode including active material particles and the like, which is used for a battery. Two-dimensional carbon including 1 to 10 graphenes is used as a conduction auxiliary agent, instead of a conventionally used conduction auxiliary agent extending only one-dimensionally at most, such as graphite particles, acetylene black, or carbon fibers. A conduction auxiliary agent extending two-dimensionally has higher probability of being in contact with active material particles or other conduction auxiliary agents, so that the conductivity can be improved.

  • Patent number: 9938771
    Abstract: An initiator nanoconstituent comprises a nanoparticle covalently bonded to a group having a free radical. The nanoparticle may be bonded to the group via an ether group or an amide group. The initiator nanoconstituent may be formed in situ, in a mixture comprising an elastomer material to be crosslinked. The initiator nanoconstituent is formed from an organic nanoconstituent compound that includes the nanoparticle and an organic group that does not include a free radical at the time the mixture is formed. At least one chemical bond of the organic nanoconstituent compound may be ruptured, in situ, to form the initiator nanoconstituent, which may then bond with polymer molecules of the elastomer material and form a crosslinked elastomer material. Downhole tools or components thereof may include such crosslinked elastomer material.

  • Patent number: 9896783
    Abstract: Methods of producing continuous carbon fibers for composites having enhanced moldability are provided. Discrete regions are introduced into a continuous precursor fiber comprising an acrylic polymer material, such as polyacrylonitrile (PAN), as the precursor fiber is formed. The precursors may be heterogeneous fibers having a second distinct material interspersed in discrete regions with the acrylic polymer material. Alternatively, the precursors may be heterogeneous fibers where laser is applied to the acrylic polymer material in discrete regions to cause localized molecular disruptions. After the continuous precursor fiber is heated for carbonization and/or graphitization, the precursor forms a continuous carbon fiber having a plurality of discrete weak regions. These relatively weak regions provide noncontiguous break points that reduce stiffness and improve moldability for carbon fiber polymeric composites, while retaining high strength levels.
