There are two kinds of electrode slice-making methods for lithium-ion power batteries, which are blade cutting and laser cutting. The edge burr of the electrode piece is large. The coating area is easy to be damaged. The quality of electrode pieces is difficult to guarantee and the qualified rate is low. Nowadays, laser cutting technology has been widely used. Since laser cutting is easy to cut any size and shape through program control, the edge of the electrode piece is free of burr and damage, and quality of the electrode piece is easy to guarantee and the qualified rate is high. However, laser cutting will produce high temperatures, which will affect active substances in the coating area, thus affecting the performance of lithium batteries.
The working principle of the Tungsten Carbide lithium battery blade internal structure of the blade is spiral, and the cathode is separated by a layer of thin-film paper with many tiny holes. Lithium-ion cell is a new type of battery energy. It does not contain metal lithium. In the process of charge and discharge, only lithium-ion moves between positive and negative electrodes, and electrode and electrolyte do not participate in the reaction. energy capacity density and weight capacity density of lithium battery slitting blade can reach 300wh / L and 125wh / L respectively. The reaction mechanism of the lithium battery slitting blade is that with the charge and discharge process. Lithium-ion is embedded and separated between positive and negative electrodes, which shuttles back and forth inside the cell without the existence of metal lithium, so the lithium-ion cell is more secure and stable. The positive electrode of the lithium-ion battery is lithium cobalt oxide, while the positive collector is aluminum foil. The negative electrode is carbon. The negative current collector is copper foil, and the electrolyte of the lithium battery slitting blade is organism dissolved LiPF6.
