GeePower® Lithium-ion Battery Knowledge Column
What is the lithium-ion pouch cell?
Lithium-ion pouch cells are liquid lithium-ion batteries with a polymer shell. Unlike other batteries, the outer surface of this battery has a flexible packaging material (aluminum-plastic composite film), which is the most critical and technically-difficult material in Lithium-ion pouch cells. The packaging material and structure of this battery brings it many advantages.
Pouch cell has the following advantages:
- High safety: its electrolyte is almost leak-free, and in case of accident, the soft-packed battery will only bulge, instead of exploding like a hard-shell battery;
- Good cycle performance: pouch cell has a longer cycle life.
- Flexible structure design: it can be made into batteries of various shapes and sizes.
- Good resistance to pressure: the battery will not explode.
- Small combined volume, small thickness, and various installation modes.
- High energy efficiency, and small temperature difference between inside and outside.
What designs do we use to ensure the safety of pouch cells?
Pouch cell packs safety design:
- A bending electrode-lug ,
- Glue filling at the bottom,
- A anti-vibration electrode-lug,
- Anti-tear design
Pouch cell system security design:
- The cells are sorted by performance identity.
- Temperature control during charging & discharging.
- System dropout voltage control.
