Description:FIELD
The present disclosure generally relates to the field of battery manufacturing. Particularly, the present disclosure relates to a system and a method for manufacturing electrode foils for a battery.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Currently, there are instances where short circuits occur in the battery consisting of layers of electrode material and separator material. These short circuits are typically caused due to the electrode material which has burrs on its edges. Further, the electrode material with the burrs also punctures the separator material. The punctures in the separator material, can elevate the risk of short circuits as it is a crucial component that prevents direct contact between the positive and negative electrodes.
The electrode material is generally obtained by subjecting an electrode sheet through a slitting process. Typically, after the slitting process burrs are formed on the edges of the electrode material. There are various techniques developed to remove burrs, such as brushing the surface of the electrode material, or employing cutting tools to remove burrs from electrode material. However, these techniques damage the surface of the electrode material, do not preserve the structural integrity of the electrode material or damage the electrode material
There is, therefore, felt a need to develop a system and a method for manufacturing electrode foils for a battery that alleviates the aforementioned disadvantages.
