BATTERY CELL HAVING IMPROVED COOLING PERFORMANCE

摘要

The present invention provides a battery cell which is characterized in that an electrode stacked body, which has a structure stacked in the height direction with respect to the ground in a state in which a separation film is interposed between a cathode and an anode, is embedded inside a battery can in a sealed state, the battery can is formed in a tubular shape having a hollow part, and the stacked electrode is formed in a shape corresponding to the shape of the battery can.
