An ultraviolet irradiation device includes an inner cylinder forming a treatment flow path, an inflow portion allowing the object to flow into the treatment flow path, an outer cylinder accommodating the inner cylinder, a light emitting element irradiating the object passing through the treatment flow path with ultraviolet light, an O-ring dividing a space provided between an outer circumferential surface of the inner cylinder and an inner circumferential surface of the outer cylinder into a first chamber through which the object before ultraviolet irradiation passes and a third chamber through which the object after the ultraviolet irradiation passes, and a second chamber communicating with the first chamber through communication holes. The second chamber communicates with the treatment flow path through a plate.

Ultraviolet irradiation apparatus and ultraviolet irradiation method

An object of the present disclosure is to provide a doping method in which the status of the progress of a main reaction can be estimated in the lithium carbonate decomposition-type doping step of a nonaqueous lithium power storage element. The separation method, the doping method, and the doping apparatus according to the present disclosure include calculating a capacitor current density iand an electrode reaction current density ibased on voltage and current of a cell that are measured during doping of the cell.

A fluid sterilization module includes an inner cylinder forming a processing flow path extending in a longitudinal direction, a first chamber communicating with the processing flow path via an opening on one end side of the inner cylinder, an inflow portion allowing an object to flow in the first chamber, an outflow portion allowing the object having passed through the processing flow path to flow out from an other end side of the inner cylinder, and a light emitting element facing an opening on the other end side of the processing flow path and irradiating the object passing through the processing flow path with ultraviolet light along the longitudinal direction. The first chamber has an inner volume equal to or more than &#x2154; of the cube of an equivalent inner diameter of the processing flow path and equal to or less than 3 times of inner volume of the processing flow path.
