Introduction of soft pack lithium battery
The soft-pack lithium battery is simply a liquid lithium-ion battery with a polymer shell. The structure is packaged in aluminum plastic film, and in the case of a safety hazard, the soft pack battery will only burst at most.
Soft pack battery advantages
1, Good safety performance
The soft pack battery does not explode like a steel shell aluminum shell.
2, Light weight
The weight of the soft pack battery is 40% lighter than the equivalent capacity of the steel shell lithium battery, which is 20% lighter than the aluminum shell battery.
3, Large capacity
The soft pack battery has a capacity of 10 to 15% higher than the steel shell battery of the same size, and is 5 to 10% higher than the aluminum shell battery.
4, The internal resistance is small
The internal resistance of the soft pack battery is smaller than that of the lithium battery. At present, the internal resistance of the domestic soft pack battery core can be as low as 35 mΩ, which greatly reduces the self-consumption of the battery.
5, Flexible design
The shape of the soft pack battery can be customized according to the customer's needs, and a new battery model can be developed.
Shortcomings of soft pack batteries
1. The existing soft pack battery cores have fewer models and cannot meet market demand;
2. The cost of developing new models is high.
What is the voltage of the soft pack lithium battery?
1. The voltage of the aluminum layer between the positive electrode and the aluminum plastic film
2. The voltage of the aluminum layer between the negative electrode and the aluminum plastic film
