What are the advantages of soft pack lithium batteries that are popular?lithium 3400mah 3.7v 18650 battery

　　1. High capacity

　　We know that the space for new energy vehicles is limited, and how to increase battery capacity within the limited space is a challenge that new energy vehicle companies have been seeking to solve. The capacity of soft pack 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 choosing a soft pack battery for the power battery of new energy vehicles will obtain higher battery capacity, thereby extending the driving range.

　　2. Lighter weight

　　The soft pack battery is packaged with aluminum plastic film, which can achieve 40% lighter than steel shell batteries of the same capacity and 20% lighter than aluminum shell batteries of the same capacity, resulting in higher energy density. Using a soft pack battery as the power battery for new energy vehicles can effectively reduce the curb weight of the vehicle. While other technical conditions remain unchanged, it can directly reduce the energy consumption of the entire new energy vehicle, thereby extending the driving range and reducing wear and tear on various parts of the vehicle.

　　3. Long service life

　　Data shows that after 100 charging cycles, the soft pack battery can experience a 4% -7% reduction in attenuation compared to aluminum shell batteries. Therefore, the soft pack lithium battery has a high safety factor and a longer service life.

　　4. Low self discharge capacity

　　The internal resistance of soft pack batteries is relatively small. Currently, the minimum internal resistance of domestic soft pack battery cells can reach below 35m Ω, greatly reducing the self consumption of the battery and effectively reducing the phenomenon of battery over discharge.
