In battery electrode manufacturing a variety of processes may be employed including coating, drying, calendering, inspection and slitting.
In battery construction, electrodes consist of a foil substrate coated with a proprietary chemical mixture. The positive electrode (anode) utilizes aluminum foil, while the negative electrode (cathode) uses copper foil. The composition of materials used in the coating process influences the battery's properties. Li-Ion batteries typically use a form of graphite on the negative cathode, while the positive anode is comprised of a lithium metal oxide blend. Conductive binders and solvents are added to create a slurry mixture that can be applied as a uniform coating...
