Publication number: 20250062349Abstract: 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.Type: ApplicationFiled: November 4, 2024Publication date: February 20, 2025Inventors: Ryota TAJIMA, Yumiko YONEDA, Yohei MOMMA, Shunpei YAMAZAKI

Patent number: 12230748Abstract: 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.Type: GrantFiled: June 30, 2022Date of Patent: February 18, 2025Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shinichiro Mori, Ryota Aoki, Hiroyasu Kado, Hiroya Takeuchi, Yuuki Yamazaki
