Aluminum wire welding technology (referred to as cold welding) can prevent electricity
The core is rusted, which also prevents secondary damage to the battery (especially Panasonic
21700 cell, this cell needs to be turned to the cell cap, turn the cap
It will cause the spot welding of the battery core cap to be weak, and also cause the battery core

to leak Liquid, and when welding nickel sheets, the battery will have welding nickel sheets
Strong, the nickel sheet burst into flames, and the excessive pressure caused the battery cell to

leak It will lead to many high-risk issues). .
Advantage 3
The overcurrent is uniform and the cell voltage difference is small.
