  • Publication number: 20240097136
    Abstract: The present disclosure provides a negative electrode for use in a lithium-ion secondary battery capable of protecting the negative electrode from breakage and cracks due to expansion and contraction of an Si-based negative electrode active material. The negative electrode is for use in a lithium-ion secondary battery and includes a negative electrode current collector and a negative electrode active material layer formed on the negative electrode current collector. The negative electrode active material layer contains, as a negative electrode active material, an Si-based negative electrode active material including Si as a component and capable of reversibly absorbing and releasing lithium ions. The negative electrode further includes a high-molecular-weight organic compound for improving durability of the lithium-ion secondary battery. The high-molecular-weight organic compound has a weight-average molecular weight of 1000 or higher.

  • Publication number: 20240097195
    Abstract: A nonaqueous electrolyte for use in a lithium-ion secondary battery, capable of reducing gas generation due to degradation of nonaqueous electrolyte, is provided. The nonaqueous electrolyte disclosed herein is for use in a lithium-ion secondary battery wherein a negative electrode active material in a negative electrode includes at least one of a Si-based negative electrode active material including Si as a component and capable of reversibly absorbing and releasing lithium ions or a graphite-based carbon negative electrode active material. The nonaqueous electrolyte contains a nonaqueous solvent and an electrolyte dissolved in the nonaqueous solvent, and further contains a cyclic carbonate and a high-molecular-weight organic compound having a weight-average molecular weight of 1000 or higher.

  • Patent number: 9016718
    Abstract: In a vehicle occupant restraint, a sub bag is inflated and deployed in an early stage at a high pressure prior to a main bag as a gas that is discharged from an inflator to the sub bag is supplied to the main bag via a communication opening. Accordingly, a lower section of the sub bag can favorably be interposed in a narrow space between a waist of a occupant and a console box. In addition, an upper section of the sub bag is supported by a top surface of the console box, and this the sub bag is firmly supported by the console box. Therefore, the main bag is supported to a same degree as when the console box is extended upward by a height of the sub bag.

  • Patent number: 9004526
    Abstract: A vehicular passive safety device includes a vehicular seat, a far-side airbag device, and a roof airbag device. The vehicular seat has a seat cushion and a seat back. In the far-side airbag device, a far-side airbag that is accommodated in a lateral portion of the seat back located inside in a vehicle width direction is supplied with a gas from a far-side inflator, and is expanded and deployed forward of the lateral portion with respect to a vehicle. In the roof airbag device, a roof airbag that is accommodated in a ceiling portion of a vehicle body is supplied with a gas from a roof inflator, and is expanded and deployed downward of the ceiling portion, and the expanded and deployed roof airbag abuts on or faces an upper portion of the expanded and deployed far-side airbag from inside in the vehicle width direction.
