As smartphones become the primary mobile Internet terminals, more and more new technologies are being applied to the smartphone field, greatly enhancing user experience. Smartphones have replaced traditional feature phones and become the mainstream in the mobile phone market. Compared to ordinary phones, smartphones have higher hardware configurations, more operational functions, and higher usage frequencies. The trend of smartphones is towards multi-core processors, larger screens, and thinner designs. This means that the power consumption of smartphones is correspondingly increased, while the space left for batteries has not increased, and there is a demand for larger battery capacities and thinner designs. Thin, high-capacity, and safer polymer batteries are favored for smart devices. Soft pack lithium-ion batteries, which have significant cost advantages compared to polymer batteries in terms of performance, have become the preferred choice, with enormous market development potential.
1,Advantages of Yungbang Soft Pack Lithium Battery
Good Safety Performance
Soft pack batteries do not explode like steel-shell or aluminum-shell cells.
Light Weight
Soft pack batteries weigh 40% less than steel-shell lithium batteries of the same capacity and 20% less than aluminum-shell batteries.
Large Capacity
Soft pack batteries have 10-15% higher capacity than steel-shell batteries of the same specifications and 5-10% higher capacity than aluminum-shell batteries.
Low Internal Resistance
The internal resistance of soft pack batteries is lower than that of lithium batteries. Currently, the minimum internal resistance of domestic soft pack battery cells can be less than 35mΩ, greatly reducing battery self-discharge.
Flexible Design
The shape of soft pack batteries can be customized according to customer needs, allowing for the development of new cell models.
2,Disadvantages of Yungang Soft Pack Lithium Battery
There are fewer existing models of soft pack battery cells, which cannot meet market demand; the cost of developing new models is high.
3,Advantages of Carbon-Coated Aluminum Foil in Lithium Battery Applications
Suppresses battery polarization, reduces heat effects, and improves rate performance.
Reduces battery internal resistance and significantly reduces the dynamic internal resistance increase during the cycle process.
Improves consistency and increases battery cycle life.
Increases the adhesion between the active material and the current collector, reducing the manufacturing cost of electrodes.
Protects the current collector from corrosion by the electrolyte.
Improves the processing performance of lithium iron phosphate and lithium titanate materials.
Coating thickness on both sides: Type A 4-6μm, Type B 2-3μm.
4,Conductive Coating
The use of functional coatings to treat the surface of battery conductive substrates is a breakthrough technological innovation. Coated carbon-coated aluminum foil/copper foil evenly and delicately coats dispersed nano-conductive graphite and carbon-coated particles on aluminum foil/copper foil. It can provide excellent static conductivity, collect microcurrent from active materials, thereby significantly reducing the contact resistance between positive/negative electrode materials and current collectors, and improving the adhesion between them. It can reduce the amount of binder used, thereby significantly improving the overall performance of the battery. Coatings come in two types: water-based (aqueous system) and oil-based (organic solvent system).
5,Performance Advantages
Advantages of Coated Carbon-Coated Aluminum Foil/Copper Foil:
Significantly improves the consistency of battery pack use, greatly reduces battery pack costs. For example:
Significantly reduces the dynamic internal resistance increase of battery cells;
Improves the consistency of pressure between battery packs;
Extends the life of battery packs;
Significantly reduces the cost of battery packs.
