1. High capacity of pouch cell lithium batteries
We know that the space for new energy vehicles is limited. How to increase the battery capacity within a limited space is a problem that new energy vehicle companies have been seeking to solve. The capacity of pouch cell batteries is 10%-15% higher than that of steel-shell batteries of the same volume, and 5%-10% higher than that of aluminum-shell batteries of the same volume. This means that the use of pouch cell batteries for power batteries of new energy vehicles will obtain higher battery capacity, thereby extending the driving range.
2. pouch cell lithium batteries are lighter
Pouch cell batteries are packaged with aluminum-plastic film, which can be 40% lighter than steel-shell batteries of the same capacity, and 20% lighter than aluminum-shell batteries of the same capacity, so the energy density is higher. Using pouch cell batteries as power batteries for new energy vehicles can effectively reduce the curb weight of the vehicle. Under the condition that other technical conditions remain unchanged, it can directly reduce the energy consumption of the whole new energy vehicle, thereby extending the driving range and reducing wear on various parts of the vehicle.
3. Long service life of pouch cell lithium batteries
Data shows that after 1,000 charging cycles, pouch cell batteries can decay 4%-7% less than aluminum-shell batteries, so they have a longer service life.
4. Good safety performance of pouch cell lithium batteries
Pouch cellk batteries are packaged in aluminum-plastic film. When the battery has thermal runaway, it will not explode like hard-pack batteries. The outer packaging can be easily expanded, and the safety performance is relatively good.
5. Flexible design of soft-pack lithium batteries
Pouch cell batteries can be freely matched with battery packs of different sizes and shapes according to customer requirements. It is relatively simple to develop battery models, and can be customized according to customer market needs to open up the battery cell models in the market.
