  • Publication number: 20230103890
    Abstract: [Problem] The present invention addresses the problem of developing a catalyst compound which has blood-brain barrier penetration properties and enables the oxygenation of amyloids in a body upon being irradiated with light from the outside of the body and providing a prophylactic and therapeutic agent for amyloid-related diseases using the catalyst compound. [Solution] It is found that a compound having such a framework that an azobenzene-like structure and boron together form a complex is useful as a novel biocatalyst which can selectively oxygenate an amyloid and can prevent the aggregation of the amyloid upon being irradiated with light while significantly reducing the molecular weight of the amyloid. It is also found that the compound can exhibit an oxygenation activity upon the irradiation with light having a longer wavelength which has high tissue penetration properties and has excellent blood-brain barrier penetration properties.

  • Patent number: 10522829
    Abstract: A method for manufacturing a positive electrode for a lithium ion secondary battery includes preparing lithium manganese complex oxide particles, preparing coated particles by forming a coating including a Li+-conductive oxide on a surface of each lithium manganese complex oxide particle, introducing fluorine into at least a part of the coated particles, preparing a fluid composition by mixing the coated particles at least a part of which fluorine is introduced into, a conductive material, an aqueous binder, and an aqueous solvent, forming a positive electrode mixture layer by disposing the fluid composition on a surface of a collector, and drying the positive electrode mixture layer. The thickness of the coating is 5 nm or more and 10 nm or less. Fluorine is introduced such that the ratio of fluorine to manganese in terms of the number of atoms in the coated particles reaches 1.95 or more and 3.1 or less.

  • Patent number: 10236530
    Abstract: A method of manufacturing a nonaqueous electrolyte secondary battery includes: manufacturing a positive electrode sheet by forming a positive electrode active material layer, which includes trilithium phosphate, on a positive electrode current collector foil; accommodating the positive electrode sheet, a negative electrode sheet, and an electrolytic solution in a battery case; and charging a battery after the accommodation. During the manufacturing of the positive electrode sheet, a positive electrode active material is a composite oxide including at least lithium and manganese. During the manufacturing of the positive electrode sheet, a conductive additive is obtained by attaching at least one of manganese or manganese oxide to a surface of a carbon material.
