What are the differences between soft pack lithium batteries and lithium batteries

What are the differences between soft-pack lithium batteries and lithium batteries? How to distinguish between lithium batteries and soft-pack lithium batteries? The three packaging lines of lithium batteries are square, soft-pack and cylinder. Among them, there is the structure of soft-pack lithium batteries. This industry is in lithium batteries. The debate over the superiority of lithium batteries and soft-pack lithium batteries has never stopped. The following is explained by the lithium battery manufacturer. What are the differences between soft-packed lithium batteries and lithium batteries? Fields of use Soft-packed lithium batteries are mainly used in mobile Internet, mobile power supplies, and digital products such as smart phones, notebook computers, and cameras. Lithium battery packs are widely used in small computer rooms, weak motor house systems, new energy outdoor venues, communication base stations, indoor and outdoor non-air-conditioned venues, radio and television, military, petroleum meteorology and other unmanned places. Features of the structure The key data for the use of soft-pack lithium batteries, the biggest difference lies in the soft-pack data (aluminum-plastic composite film), which is the most critical and technically difficult data in soft-pack lithium batteries. Flexible packaging information is generally divided into three layers, namely the outer resistance layer (usually the outer protective layer composed of nylon BOPA or PET), the penetration resistance layer (aluminum foil middle layer) and the inner layer (multifunctional high barrier layer). Lithium battery pack: Lithium battery is used as an assembled form of lithium battery pack, with higher energy ratio, longer service time and longer life. The important components of a lithium battery pack are positive and negative electrodes, electrolyte and gaps. The energy ratio and weight of soft-packed lithium batteries are 40% lighter than steel lithium batteries of the same capacity and 20% lighter than aluminum batteries. The capacity of steel batteries is 10-15% larger than that of aluminum batteries. The energy density of lithium battery packs is 3-4 times that of lead-acid batteries, 2.5 times that of nickel-cadmium batteries, and 1.8 times that of nickel-hydrogen batteries. Therefore, with the same battery capacity, lithium batteries will be smaller and lighter than lead-acid batteries, nickel-cadmium batteries and nickel-hydrogen batteries. Advantages of soft-packed lithium batteries 1. Good safety features Soft-coated batteries are different from steel and aluminum-coated batteries, and they will explode. 2. The weight of the 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 batteries is 10-15% larger than steel batteries and 5-10% larger than aluminum batteries. 4. The internal resistance of the soft-pack battery is small. The internal resistance of the lithium battery is small. At present, the internal resistance core of the soft-pack battery can be made at least 35m below, which greatly reduces the power consumption of the battery. 5. Sensitive design The shape of the soft pack battery can be customized according to the needs of customers, and new battery types can be developed. Advantages of energy storage lithium battery packs. PNG1. Long service life lithium iron phosphate battery pack, 1C charge and discharge at room temperature, the monomer capacity is still greater than 80% after 2000 cycles, and the 3C cycle life reaches more than 800 times. 2. Fast charging and high current 2C can quickly charge and discharge. Charging in a dedicated charger 1.5c, the battery is fully charged within 40 minutes, and the starting current can reach 2C. 3. The thermal peak value of lithium iron phosphate battery pack for high temperature applications can reach 350~500, and the working temperature range is wide (-20~+75). 4. It is safe and environmentally friendly. Lithium iron phosphate has passed strict safety tests and will not explode even in a fierce collision. It does not contain any heavy metals and rare metals, is non-toxic, and is non-polluting regardless of processing and use. It complies with European RoHS regulations and is a green battery. 5. There is no recall effect. Regardless of the state of the lithium battery pack, it can be used at any time, do not charge it completely. The above are the differences between soft pack lithium batteries and lithium batteries, and their respective advantages. I believe you know how to distinguish between lithium batteries and soft pack lithium batteries. It is not difficult to see that soft-pack lithium batteries and lithium batteries have their own characteristics, depending on the scale of your use, the choices are different.
