Analysis on the advantages and disadvantages of soft pack lithium batteries

What does the edge voltage of a soft-pack lithium battery refer to? A soft-core lithium battery Introduction A soft-pack lithium battery is a liquid lithium battery simply wrapped in a polymer shell. In the structure, choose aluminum-plastic film packaging, the soft pack battery will only burst in the case of safety hazards. Advantages and disadvantages of soft lithium batteries Advantages of soft-pack batteries 1. Good safety performance Soft-clad batteries are different from steel-clad aluminum-clad batteries, and they will explode. 2. The light weight soft pack battery is 40% lighter than the steel shell lithium battery of equal capacity and 20% lighter than the aluminum shell battery. 3. The capacity of large-capacity soft-shell batteries is 10-15% larger than that of steel-shell batteries and 5-10% larger than that of aluminum-shell batteries. 4. The low internal resistance of the soft pack battery is a lithium battery with a low internal resistance. At present, the internal resistance core of the soft pack battery is less than 35m in China, which greatly reduces the power consumption of the battery. 5. Flexible plan The shape of the soft pack battery can be customized according to the needs of customers, and new battery types can be developed. Defects of soft-pack batteries 1. There are few types of soft-pack batteries that cannot meet market demand; 2. The high cost of developing new types. What is the edge voltage of the soft pack lithium battery? 1. The aluminum layer voltage between the positive ear and the aluminum plastic film 2. The aluminum layer voltage between the negative ear and the aluminum plastic film. Theoretically, the positive and negative electrodes are insulated with the aluminum plastic film , Which means that their voltage should be 0. In fact: Considering the battery materials and their processing process, some damage can occur, which promotes a part of the conduction between them (including electron channels and ion channels), and the formed microbattery, There may be different (voltage). The higher the voltage, the higher the possible danger of the battery. The voltage is regulated by each manufacturer. Most industries have ratings below 1.0V.
