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).
