However, the slitting and cutting of the cell stacking sheets is cumbersome, and each battery has dozens of small pieces, which is prone to defective products, so the single battery of the stacked sheet is prone to problems such as cross section. Blade cells, this form is naturally more suitable for stacking.
Stacking plays a key role in the battery cell production process: stacks are formed from individual electrode sheets and a separator film fed in as a continuous web to form the core of the subsequent battery cell. The precision of the stacking process has a decisive influence on the quality and service life of the subsequent battery cell.
Although the stacking process will expand during the repeated use of the battery, in general, the expansion force of each layer is similar, so the interface can be kept flat. The plates at both ends of the winding are bent, the coating material will be greatly bent and deformed, and powder dropping and burrs will easily occur at the bending place.
At the same time, problems such as powder dropping and burrs are prone to occur at the bends, and the pole piece and diaphragm are subject to tension, which is prone to wrinkles and unevenness. The battery cell stacking is uniformly stressed and deformed less, and the safety of the battery cell is higher.
Prismatic cell: Both stacking and winding processes can be used. At present, the main technology direction in China is mainly winding and is transiting to stacking. Cylindrical cell: As a mature product, it always with the winding process. 4. What are the benefits of lithium-ion battery cell that formed by stacking process?
Cycle life is one of the key properties of batteries. The cell stacking battery has more tabs, the shorter the electron transmission distance, and the smaller the resistance, so the internal resistance of the stacked battery can be reduced, and the heat generated by the battery is small.

The stacking time for one battery cell is about 3 to 5 minutes. The efficiency is extremely slow. Based on the traditional "Z"-shaped stacking machine, an all-in-one cutting and stacking machine has been developed, which integrates a die-cutting machine and a glue hot press. That is, the die-cut pole pieces do not need to be re-stacked, but can be cut into pieces …
While undergoing nail penetration tests, Blade Battery emits neither smoke nor fire after being penetrated, and its surface temperature only reaches 30 to 60° C.
