About the machine vision alignment detection of lithium battery pole pieces?

About the machine vision alignment detection of lithium battery pole pieces? In the winding process of lithium battery production, the positive and negative electrodes are placed in the separator.   The negative electrode needs to exceed the positive electrode by a certain margin in the width direction, and the separator exceeds the negative electrode by a certain margin.   The […]

About lithium battery winding machine?

About lithium battery winding machine? The important technology of lithium-ion battery winding equipment is to control the tension of the separator and plate and to wind at a constant speed. The quality of plate tension control directly determines the quality of battery production. The quality of the tension also directly affects the balance and production capacity of the battery winding […]

About battery vacuum baking?

About the slitting machine? Lithium battery electrolyte is an organic substance without water molecules. If the water content is too high, the product will be scrapped, the quality will deteriorate, and even the product will explode. Therefore, before the battery is filled with liquid and sealed, it must be vacuum baked. This is necessary, and the purpose is to remove […]

About the slitting machine?

About the slitting machine? The pole piece slitting machine is the equipment for slitting the rolled battery pole piece according to the battery specification. Slitting type: 1.
