Publication number: 20240079583Abstract: A novel method for forming a positive electrode active material is provided. The method for forming a positive electrode active material includes causing a reaction between a cobalt aqueous solution and an alkaline aqueous solution to form a cobalt compound; mixing the cobalt compound and a lithium compound and performing a first heat treatment to form a first composite oxide; mixing the first composite oxide and a compound containing a first additive element and performing a second heat treatment to form a second composite oxide; and mixing the second composite oxide and a compound containing a second additive element and performing a third heat treatment. The first heat treatment is performed at a temperature higher than or equal to 700° C. and lower than or equal to 1100° C. The second heat treatment is performed at a temperature higher than or equal to 700° C. and lower than or equal to 1000° C.Type: ApplicationFiled: January 13, 2022Publication date: March 7, 2024Inventors: Kazuya SHIMADA, Kousuke SASAKI, Takashi HIRAHARA, Yusuke YOSHITANI, Mayumi MIKAMI, Yohei MOMMA

Patent number: 11886025Abstract: A receptacle (6) includes an optical fiber stub (7). A lens (5) includes an incident-side curved surface (9), an emission-side curved surface (10), and a barrel (11) provided between the incident-side curved surface (9) and the emission-side curved surface (10). A receptacle holder (8) holds the receptacle (6) so that the lens (5) and the optical fiber stub (7) are not in contact but separated from each other. When light out from the optical fiber stub (7) enters the lens (5) through the incident-side curved surface (9), the light is condensed inside the lens (5) and then spreads again, and the light out from the emission-side curved surface (10) is condensed onto a light-receiving surface of the light-receiving device (2).Type: GrantFiled: November 16, 2018Date of Patent: January 30, 2024Assignee: Mitsubishi Electric CorporationInventor: Yohei Mikami
