Aluminium Foil 8 Micron Big Roll
As the name suggests, the current collector is a structure or part that collects current, and it is one of the indispensable components in lithium-ion batteries. The aluminum foil is often used as the current collector of the positive electrode in the lithium battery. Everybody here knows better that the positive electrode is made of aluminum foil, the negative electrode is made of copper foil, and the middle is separated by a separator.
In fact, aluminum foil accounts for a very small proportion of the entire battery, less than 1%, but its effect is very large. I often communicate with customers, saying that our aluminum foil is "loading forward", because the unit price of aluminum foil is very low, and its proportion in the battery is very small, but the positive electrode material attached to it is very expensive. One hundred thousand, so the value of aluminum foil itself is not high, but the value of the material attached to the body is very expensive.
Aluminum foil is collectively referred to as aluminum foil below 0.2 mm, which is a qualitative effect of aluminum processing on it. The current aluminum foil is divided into thick foil, single zero foil, and double zero foil. The current aluminum foil technology can be as thin as 4.5 micrometers, but the 9u that is actually used on lithium batteries, the thinnest power is now used by domestic head companies. 10u. These are three products related to new energy. This one has not undergone some surface treatment and processing. The thickness is 8 micrometers to 0.03 mm, to 30 micrometers, and the width is basically 250 to 1450. 250 is used more on the experimental line. The current mass production line is between 400 and 600, and the widest power is 6380
Aluminum foil for batteries, from the earliest days of entering the industry in 2009, was completely unreasonable, and I don't understand how to make this aluminum foil. At the beginning, we used traditional aluminum foil products. It may be clear to everyone here. It is mainly used for food packaging aluminum foil, including our medicine packaging, including the aluminum foil for men’s cigarettes for boys. That is 6 microns. The thickness of this aluminum foil is basically used in women’s facial mask packaging bags, Wahaha and Master Kong packaging. In fact, aluminum foil is used in all aspects of life.
Food Grade 12 Micron Aluminum Foil Coil 8011 O Wrap stuffed and folded, cooked things in tin foil. It's our favorite new dinner format, with zero cleanup work. It's perfect. Forget those dirty dishes and dishes.
