12 um Aluminum Foil for Battery Cathode
Application of aluminum foil in lithium batteries
The positive electrode sheet is lithium iron phosphate coated on aluminum foil, but lithium iron phosphate is preferred. The negative electrode is copper foil coated with graphite or lithium titanate. There is a separator between the positive and negative foils, which are wound together. Put the rolled positive and negative sheets (including separators) into the battery case together, inject electrolyte, and then vacuum seal to complete the production of a single battery.
In lithium batteries, copper foil is not only the carrier of the negative active material, but also the collector and conductor of negative electrons. Therefore, it has special technical requirements, that is, it must have good conductivity, and the surface can be evenly coated with negative electrode materials without Shedding, and has good corrosion resistance. In order to ensure that the negative electrode material coated on the electrolytic copper foil will not fall off, a suitable binder must be added during preparation.
With the rapid development of the lithium battery market, the industry expects that the consumption of lithium battery aluminum foil will reach about 80,000 tons by 2020.
Lithium battery aluminum foil can be divided into power battery foil, consumer battery foil, and energy storage battery foil. Among them, power battery foil currently has the largest demand, accounting for more than 50%, while the consumer battery aluminum foil market is basically saturated. Industry analysts believe that the demand for aluminum foil for power batteries will further increase in the future, and aluminum foil for energy storage batteries will also gradually gain momentum.
