A stacked sodium ion battery structure is adopted. By setting up components such as fixed columns, bidirectional threaded rods, clamp columns and adjustment columns, the mutual cooperation of these components is used to achieve automatic connection between the positive electrode ear and the negative electrode ear, avoiding the need for using aluminum water.
The operation process of battery connection is simplified, reducing the risk of staff being scalded by aluminum water. At the same time, through the coordination of springs and buffer columns, the probability of clamp columns being loose due to thermal expansion and contraction is reduced.
