6 FAQs about [Blade battery module stacking technology]

What are the characteristics of a cell stacking battery?

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.

What is the difference between a module and a blade battery?

The height of the Blade Battery is reduced by ~50 mm, compared with regular LFP battery back with modules, providing more space to the passengers and decreasing the coefficient of drag (0.233 cd for BYD Han). In the Z direction, the structure of the Blade Battery is completely different from conventional module-based battery packs (Figure 3).

What is the difference between a stacked battery and a blade cell?

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.

What is a blade battery?

The structure of the Blade Battery from cell to pack. At the center of the design of the Blade Battery is the cell geometry, which has a much lower aspect ratio compared with conventional cylindrical or prismatic cells. According to BYD’s patents, the cell depth (Z axis) is 13.5 mm while the cell length (X axis) can range from 600 mm to 2500 mm.

What is the potential of a Super-stacking & blade battery?

The largest potential is the wound large cylindrical battery, which is because of the dry electrode technology that has been introduced around the mature technology. Cell stacking is the fastest growing. Chinese battery companies are starting to design super-stacking + blade battery solutions. Many overseas companies are trying.

Which type of battery is suitable for stacking?

Blade cells, this form is naturally more suitable for stacking. This is because the length of the blade cell is 960mm and the height is 90mm. The blade battery is produced by the cell stacking process, the alignment can be controlled within 0.3mm, and the stacking efficiency is 0.3s/pcs. 4.
