Performance parameters, advantages and disadvantages of soft pack lithium batteries

The parameters, advantages and disadvantages of soft lithium batteries As smart phones become the most important mobile Internet terminal, more and more new technologies are applied to the category of smart phones, which greatly improves the user's operating experience, and smart phones replace traditional mobile phones. The function of the mobile phone market has become the mainstream. Compared with ordinary mobile phones, smart phones have higher hardware configuration, more operating functions, and higher application frequency than traditional mobile phones. Multi-core, large screen, and thinness have become the development trend of smart phones. This means that smart phones consume more power, have no battery space, and require larger and thinner batteries. Smart phones favor thin, high-capacity, and safer polymer batteries. There is little difference in function from polymer batteries, but the cost advantages are obvious. The soft-packaged lithium battery has become the first choice, and the market has huge room for development. Advantages of soft-packed lithium batteries 1. Good safety performance Soft-packed batteries are different from steel-clad aluminum-clad batteries. They will explode. 2. The weight of the soft pack battery is 40% lighter than the steel case of equal capacity and 20% lighter than the aluminum case. 3. Compared with the steel shell battery of the same specification, the capacity of the soft shell battery is increased by 10~15%, and the capacity of the aluminum shell battery is increased by 5~10%. 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 is less than 35m in China, 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. Soft lithium batteries have their shortcomings. There are few types of soft pack batteries and cannot meet market demand; the cost of developing new models is high. Application advantages of carbon aluminum foil in lithium batteries 1. Inhibit battery polarization, reduce thermal effects, and increase multiplier; 2. Reduce battery internal resistance, significantly reduce the dynamic internal resistance rise during the cycle; 3. Continuous improvement, improve battery Cycle life; 4. Adhesion between the progressive active material and the collecting liquid, reducing the manufacturing cost of the electrode; 5. Preventing the collecting liquid from being corroded by the electrolyte; 6. Improving the production function of lithium iron phosphate and lithium titanate materials. Coating thickness on both sides: Type A 4~6cm, Type B 2~3cm. Conductive coating The surface treatment of the conductive substrate of the battery by the functional coating is a breakthrough technological innovation. The carbonaceous aluminum foil/copper foil is dispersed on the nano-conductive graphite and carbonaceous coating particles, uniformly and delicately. Coated on aluminum foil/copper foil. It can provide excellent static conductive function and collect active materials in the clinic, so it can greatly reduce the contact resistance between the positive/negative electrode materials and the collector, and can improve the adhesion between the two, which can reduce the adhesion. The use of binding agent, therefore, the overall function of the battery is significantly improved. There are two types of coatings: water-based (aqueous system) and oil-based (organic solvent system). Disclaimer: Some pictures and content of articles published on this site are from the Internet.
