Background
A lithium ion battery is a secondary battery (rechargeable battery) that operates mainly by means of lithium ions moving between a positive electrode and a negative electrode. During charge and discharge, lithium ions are inserted and extracted back and forth between the two electrodes: during charging, lithium ions are deintercalated from the positive electrode and are intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true when discharging.
The positive plate of the lithium ion battery is a plate-shaped structure formed by compounding a positive electrode material and a conductive current collector in the lithium ion battery. The positive plate of a lithium ion battery is usually formed by compounding aluminum foil and a positive electrode material. Aluminum foil is a thin and rigid sheet of metal that can serve as a current collector, i.e., a conductive support, for the electrodes. The positive electrode material is a powdery composite, and is composed of active material particles, a conductive agent, a binder and pores. Common positive electrode materials are lithium cobaltate, lithium nickel cobalt manganate, lithium iron phosphate and the like.
The positive plate of the lithium ion battery needs to be blanked so as to be cut into a required shape and size according to the design structure and specification of the battery. Blanking is a processing method for cutting or punching a metal or nonmetal plate by using a die. The blanking can improve production efficiency, reduce cost and ensure size precision and surface quality. Processing aluminum foil into round sheets is a common blanking process that can be used to make wound or laminated lithium batteries.
