Description

Technical Field

[0001] This invention relates to the field of sodium-ion battery technology, and more specifically to a stacked sodium-ion battery. Background Technology

[0002] Sodium-ion batteries are rechargeable secondary batteries that use sodium ions as charge carriers. During charging and discharging, sodium ions move between the positive and negative electrodes. Stacked sodium-ion batteries are sodium-ion batteries that use a layered or stacked structure design.

[0003] When stacking sodium-ion batteries, workers need to place one battery on the placement plate of the stacking frame, place another battery on top of the first battery, and insert the card plate at the bottom of the second battery into the card slot at the top of the first battery. Following the above steps, the battery bodies are stacked one by one in the stacking frame to limit each other. Finally, bolts are used to connect and fix the top and bottom battery bodies to the stacking frame.

[0004] Because the battery cells are mutually constrained during the stacking process of sodium-ion batteries, if a single battery cell is damaged, it is necessary to remove the upper-layer battery cells one by one, which is inconvenient. Furthermore, the battery cell sizes vary depending on the application scenario, and the height of the stacking frame cannot be adjusted according to the battery cell size, resulting in wasted or insufficient stacking frame space, thus reducing the stacking efficiency of sodium-ion batteries. Therefore, there is an urgent need to design a stackable sodium-ion battery to solve these problems. Summary of the Invention
