Abstract: To accurately detect the moving state of secondary atomic ions at the time of targeted voltage application and the moving state of secondary atomic ions due to diffusion. An ion movement measuring device includes a test specimen and a detector. The test specimen has a first electrode, a second electrode, and an electrolyte disposed between them. The first electrode and the second electrode each have a layer of an identical element, and have the identical potential in a state where no voltage is applied from outside the test specimen. At least the first electrode contains second atoms being isotopes of first atoms at an abundance ratio higher than a natural abundance ratio of the second atoms, the first atoms being present at a highest natural abundance ratio in the element. The detector detects some of ions of the first atoms and the second atoms, which are discharged from the electrolyte.

Abstract: To detect the state of a slurry during stirring without exposure to the atmosphere and with high accuracy. A stirring tank stores a slurry for a battery without exposure to the atmosphere. A stirring device stirs the slurry in the stirring tank. An observation container is coupled to the stirring tank. A circulation device circulates the slurry between the stirring tank and the observation container without exposure to the atmosphere. A detection device detects the state of the slurry by irradiating the slurry in the observation container with X-rays and detecting the X-rays transmitted through the slurry.
