    Abstract: To provide a battery cell structure capable of improving heat dissipation without degradation of an energy density and an obstacle to size reduction while an electrode layer of a battery cell has sufficient heat transfer properties. The present invention relates to a cell structure including a positive/negative electrode formed in such a manner that a conductive base member having a three-dimensional structure contains an electrode active material and a collector formed continuously to the positive/negative electrode. One surface of the collector is formed continuously in a longitudinal direction of the positive/negative electrode (across a large area), and the other surface of the collector is exposed in a longitudinal direction of the cell structure (across a large area).

    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.
