  • Publication number: 20240250334
    Abstract: Provided are a thermal runaway suppression sheet with maximum thickness of 3 mm or less and capable of insulating to temperature at which a propagation of thermal runaway in a lithium ion battery can be suppressed, and a battery pack and a battery module. The thermal runaway suppression sheet includes a thermal energy consumption layer containing a silica-based inorganic fiber having a hydroxyl group, and a thermal diffusion layer having a thermal conductivity in the planar direction that is 10 to 200 times as high as the thermal conductivity in the thickness direction. The thermal runaway suppression sheet has a thickness of 3 mm or less. When the thermal runaway suppression sheet is locally heated, the thermal energy consumption effect based on the silica-based inorganic fibers contained in the thermal energy consumption layer can be efficiently utilized by the thermal conduction along the planar direction of the thermal diffusion layer.

  • Patent number: 11951677
    Abstract: A three dimensional manufactured product is manufactured A speed of filing an uncured light curing resin in a space for a next layer is enhanced, to improve a manufacturing speed. One surface of a container housing a light curing resin is configured by a gas-permeable sheet that faces the light curing resin, and transmits irradiation light of a light irradiating apparatus, and a light transmitting plate disposed at an outer side of the container from the gas permeable member. A pressurizing chamber controllable in pressure by a pressure controlling apparatus is defined between the gas-permeable sheet and the light transmitting plate. At moving a manufacturing stage, an inside of the pressurizing chamber is de-pressurized to cause the gas-permeable sheet to perform concave surface deformation, and at a time of performing light irradiation, gas in the pressurizing chamber is caused to permeate into the light curing resin by pressurizing.
