  • Patent number: 10676603
    Abstract: A method for producing a resin composition is provided. The method includes melting and kneading a thermoplastic resin having a transition temperature of less than 200° C. and a powder with a twin-screw kneading extruder. The powder is an inorganic filler having an apparent density of 0.1 to 1.5 g/ml. The resin is supplied from a supply port to the extruder, and the powder is supplied from a gravimetric feeder to the extruder through a screw type side feeder. A transport capacity of the side feeder is 2 times or more an effective volume of the powder per unit time. In the extruder, melting and kneading are performed under conditions in which resin pressure in a first kneading zone is 1 MPa or more, and resin pressure in a second kneading zone is less than 3 MPa, and gas is removed from a vent port.

  • Patent number: 9979016
    Abstract: A negative electrode active material for an electric device according to the present invention includes crystalline metal having a structure in which a size in a perpendicular direction to a crystal slip plane is 500 nm or less. More preferably, the size in the perpendicular direction to the crystal slip plane is controlled to become 100 nm or less. As described above, a thickness in an orientation of the slip plane is controlled to become sufficiently small, and accordingly, micronization of the crystalline metal is suppressed even if breakage occurs from the slip plane taken as a starting point. Hence, a deterioration of a cycle lifetime can be prevented by applying the negative electrode active material for an electric device, which is as described above, or a negative electrode using the same, to an electric device, for example, such as a lithium ion secondary battery.
