What are the advantages of aluminum foil in the field of lithium batteries?

Advantages of aluminum foil in the field of lithium batteries 1. Extend the service life of lithium batteries. Because special aluminum foil has better physical functions, the cycle function of lithium batteries has been significantly improved. 2. Improve the consistency of the lithium battery. The use of special aluminum foil can not only reduce the internal resistance, but also improve the consistency of the internal resistance. 3. Improve the rate discharge function of the battery. After the special aluminum foil is selected, the rate function of the lithium battery advances significantly, especially in the case of large rate (greater than 3C), the rate discharge capacity advances above 15%, perhaps in the case of equal rate Below, special aluminum foil can travel the energy density of lithium batteries. The advantages of carbon-coated aluminum foil in the application of lithium batteries: inhibit battery polarization, reduce thermal effects, and improve rate performance; reduce battery internal resistance, and significantly reduce the dynamic internal resistance increase in the cycle process; improve consistency, and add lithium battery cycling Life; improve the adhesion between the active material and the current collector, reduce the manufacturing cost of the pole piece; protect the current collector from corrosion by the electrolyte; improve the production performance of lithium iron phosphate and lithium titanate materials. The performance advantages of carbon-coated aluminum foil/copper foil: Significantly improve the consistency of the battery pack and greatly reduce the cost of the battery pack; improve the adhesion of the active material and the current collector, the material is soft, easy to produce, and the pole piece manufacturing cost is reduced; Polarization increases the rate and gram capacity, and improves the performance of lithium batteries; protects the current collector and prolongs the battery life.
