FIXING STRUCTURE FOR ELECTRODE TABS OF BATTERY CELLS IN A POUCH CELL BATTERY

The present invention provides a fixing structure for electrode tabs of battery cells in a pouch cell battery, comprising two bus structures with a battery cell module positioned therebetween. Each bus structure includes a support seat and multiple busbars, with each busbar forming a joining surface. Multiple first electrode tabs of the battery cell module pass through the support seat and are bent to form first bent tab portions contacting the respective joining surfaces, while multiple second electrode tabs pass through the support seat and are bent to form second bent tab portions contacting the respective first bent tab portions. Each first bent tab portion is positioned between the corresponding joining surface and second bent tab portion, with the sequentially contacting busbar, first bent tab portion, and second bent tab portion being welded together.
