Abstract:
1. A method for manufacturing an electrode for an electrochemical element, comprising: a deposition step of allowing lithium to deposit on a substrate provided with a layer capable of forming a compound together with lithium; a first beta ray irradiation step of emitting a first beta ray using a first beta radiation source and a second beta ray using a second beta radiation source that includes a different type of nuclide from a nuclide of the first beta radiation source, toward the substrate for irradiation before the deposition step; a first measurement step of measuring backscattering, from the substrate, of the first beta ray and the second beta ray emitted in the first beta ray irradiation step; a second beta ray irradiation step of emitting the first beta ray and the second beta ray toward the substrate for irradiation after the deposition step; a second measurement step of measuring backscattering, from the substrate, of the first beta ray and the second beta ray emitted in the second beta ray irradiation step; a calculation step of calculating a decrement in backscattering of the first beta ray and a decrement in backscattering of the second beta ray, using results obtained in the first measurement step and results obtained in the second measurement step; and a control step of controlling the deposition step depending on the decrement in backscattering of the first beta ray and the decrement in backscattering of the second beta ray.
