To make 8021 Aluminum Foil Pharmaceutical Foil, it is necessary to mount the calendered sheet on offset paper with a substance such as sodium silicate so that it can be printed. Aluminum foil can be used not only for hot stamping, but also for screen printing, gravure printing, and other printing processes.
By using rolled aluminum foil as a positive collector, the lithium-ion battery industry is able to realize the following advantages:
Reducing the internal resistance of the battery: Aluminum foil has excellent electrical conductivity, which reduces the resistance of the current inside the battery, thus improving the charging and discharging efficiency of the battery.
Improve battery charging and discharging efficiency: Due to the low internal resistance characteristics of 8021 Aluminum Foil Pharmaceutical Foil, the energy loss of the battery during charging and discharging is reduced, thus improving the charging and discharging efficiency of the battery.
Extend the service life of the battery: By optimizing the material and structure of the collector, the service life of the battery can be extended. The stability and corrosion resistance of aluminum foil helps maintain the performance and life of the battery.
There are two common processing routes used in the industry today, namely the ingot hot rolling method and the double-roll casting and rolling method.

GNEE utilizes the ingot hot rolling method:
The ingot hot rolling method is a traditional processing technology, and its basic process includes ingot casting, heating, hot rolling, rolling, annealing and other steps. First of all, the raw material will be heated to a certain temperature of aluminum ingot, so that it softens and has a certain degree of plasticity. Then, through the hot rolling mill will be rolled into a certain thickness of aluminum ingot plate. In the rolling process, it is necessary to control the temperature, the amount of underpressure, rolling speed and other parameters to ensure that the thickness of the plate, surface quality, mechanical properties and other indicators. Finally, the rolled plate is annealed to eliminate internal stress, improve the plasticity and toughness of the plate.
alu foil use：
The advantages of the ingot hot rolling method are mature process, simple equipment and low cost. However, due to the ingot heating process is prone to produce oxides and inclusions, so the heating temperature and time need to be strictly controlled to avoid the impact on product quality. In addition, the thickness of the plate produced by the ingot hot rolling method is large, so it needs to be rolled and annealed for many times, and the production cycle is long.
GNEE Aluminum Co., Ltd. is located in Anyang City, Henan Province. Our company is an excellent enterprise integrating the production, processing and sales of aluminum foil.
