  • Publication number: 20250062349
    Abstract: Use of silicon as a negative electrode active material particle causes a problem of expansion and contraction of the negative electrode active material particle due to charging and discharging. A negative electrode active material particle or a plurality of negative electrode active material particles are bound or fixed using a graphene compound to inhibit expansion and contraction of the negative electrode active material particle due to charging and discharging. In an all-solid-state secondary battery, an interface between a solid electrolyte and a negative electrode or an interface between the solid electrolyte and a positive electrode has the highest resistance. In order to reduce the interface resistance, at least the negative electrode active material particle is surrounded by a graphene compound to increase the conductivity. Alternatively, a positive electrode active material particle is surrounded by a graphene compound to increase the conductivity. Carrier ions, e.g.

  • Patent number: 12230748
    Abstract: A method of manufacturing adhered components includes a process of applying adhesive to application areas on a surface of a first component, a process of placing a second component above the first component, and a process of pressurizing the second component toward the first component. In the pressurization process, the load applied to a pressurizer changes while sequentially undergoing a curvilinear increase period in which the load increases in a curved line as the compression amount of the adhesive increases, and a rapid increase period in which the load increases in a polygonal line with respect to the trajectory of the load in the curvilinear increase period as the compression amount increases. During pressurization by the pressurizer, the load is detected by a load sensor, the rapid increase period is detected based on the detection value of the load sensor, and the pressurization is stopped during the rapid increase period.

  • Patent number: 11446892
    Abstract: A first sheet panel is folded along a first fold line, and thereby a first folded part is formed in the first sheet panel. Subsequently, the first folded part is folded back along a second fold line, and thereby a folded-back part is formed in the first sheet panel. A corner cut device cuts a second sheet panel and the folded-back part to form corner cut parts. At this time, the corner cut device prevents the first folded part and a base part of the first sheet panel from being cut.
