    • An energy storage device includes a plurality of unit cells stacked therein, each of the unit cells including a cell body, a positive terminal disposed at one side of the cell body, and a negative terminal disposed in the cell body to form a constant rotation angle with the positive terminal with reference to a center of the cell body, wherein the plurality of cell units are stacked in such a manner that another unit cell is rotated as much as the constant rotation angle with reference to one unit cell. Temperature distribution, that is, heat distribution in the energy storage device can be kept even, and heat transmission efficiency between the terminals and the external air can be improved and thus cooling efficiency can be improved. Also, a resistance value is reduced by improving a cooling function so that performance and reliability of a product can be improved.
    • 能量存储装置包括堆叠在其中的多个单元电池,每个单电池包括电池体,设置在电池体一侧的正极端子和设置在电池体中以形成恒定旋转角度的负极端子 其中参考电池体的中心具有正极端子,其中多个电池单元以这样的方式被堆叠,使得另一个单电池相对于一个单元电池旋转恒定的旋转角度。 能够均匀地保持储能装置的温度分布,即热分布,能够提高端子与外部空气的传热效率,提高冷却效率。 此外,通过提高冷却功能来降低电阻值,从而可以提高产品的性能和可靠性。
