100x65x0.7mm Circular Slitter Blades For Li Battery Electrodes

Aluminum Foil Slitter Blade for Lithium Battery Electrodes Top And Bottom Knife

The slitting of coated aluminum and copper foil used in Lithium Battery Production requires highly precision circular slitting blades. The blades’ production need to follow micron level tolerances, which is challenging for most of knife manufacturers. With more than 20 years’ experience, we can take care of the slitting blades’ outer diameter, inner diameter, thickness, concentricity, flatness and other parameters under strict control within the industry’s standards, or even surpassing the standards!

The coated foils are subsequently fed into slitting machines to cut the foil into narrower strips suitable for different sizes of electrodes. Later they are cut to length. Any burrs on the edges of the foil strips could give rise to internal short circuits in the cells so the slitting machine must be very precisely manufactured and maintained.
