摘要： The present invention makes a lithium ion secondary cell exhibit high capacity when lithium manganese phosphate is used as the active material of the lithium ion secondary cell. The present invention is directed to lithium manganese phosphate nanoparticles having a ratio I20/I29 of the peak intensity at 20° to the peak intensity at 29° obtained by X-ray diffraction of greater than or equal to 0.88 and less than or equal to 1.05, and a crystallite size determined by X-ray diffraction of greater than or equal to 10 nm and less than or equal to 50 nm.

摘要： A method for producing an active material particle for a lithium ion battery, the method including steps of: flowing a plurality of raw material solutions into respective raw material-feeding channels under a pressure of 0.3 to 500 MPa, the solutions being capable of inducing a chemical reaction when mixed, thereby producing an active material particle for a lithium ion battery or an active material precursor particle for a lithium ion battery; and mixing the plurality of raw material solutions at a junction of the raw material-feeding channels to induce the chemical reaction, thereby continuously producing an active material particle for a lithium ion battery or producing an active material precursor particle for a lithium ion battery.

摘要： A prepreg which is suitable for producing a fiber-reinforced composite material in a short period of time without using an autoclave, can produce a fiber-reinforced composite material in which the occurrence of voids is suppressed and excellent impact resistance is achieved, and has excellent handling properties; and a fiber-reinforced composite material using the prepreg. This prepreg is a prepreg in which a reinforcing fiber [A] arranged in layers is partially impregnated with an epoxy resin composition containing an epoxy resin [B] and a curing agent [C], wherein the impregnation rate φ is 30-95%, and a thermoplastic resin [D] insoluble in the epoxy resin [B] is unevenly distributed on both surfaces of the prepreg. In addition, in the layers of the reinforcing fiber [A], epoxy resin composition-unimpregnated portions are localized on one surface of the prepreg, and the localization parameter a, which defines the degree of localization, is in the range of 0.10
