significance
The significance of preparing battery pole pieces on aluminum foil or copper foil is to provide a good electrode material so that the battery can work normally and have good performance. Aluminum foil or copper foil can be used as a current collector or electrode material for batteries to prepare various electrochemical energy storage devices such as lithium-ion batteries and supercapacitors.
Aluminum foil or copper foil has good electrical conductivity, which can effectively transfer charges and increase the electrical conductivity of the battery, thereby increasing the output power of the battery. At the same time, it has high strength and hardness, which can provide better mechanical support and stability for the battery, and avoid problems such as deformation or fracture during use. It can resist the chemical reaction in the battery and avoid the failure or corrosion of materials in the battery.
So, how to prepare battery pole pieces on aluminum foil and copper foil? How to prepare by coating machine? The following is to inform:
Preparation
The preparation of battery pole pieces on aluminum foil and copper foil can be carried out by an automatic film coating machine. The vacuum adsorption function of the film coating machine can maintain the flatness of the aluminum foil and copper foil . This is the key to the coating film. The specific film coating steps are as follows:
Prepare the base material: choose suitable aluminum foil and copper foil as the base material, and cut it into the required size and shape. Then, carry out the necessary cleaning treatment on the surface to remove impurities such as grease, oxides, and dirt.
Preparation of slurry : Select suitable electrode materials and conductive additives, such as carbon black, conductive fibers, etc., and mix and stir according to the ratio and requirements of the required electrode materials.
Adjust the film coating machine: choose a suitable film coating machine, adjust the gap and pressure of the film coating machine according to the thickness and width of the required electrode material , and ensure that the coating film has a uniform thickness and is well adhered to the surface of aluminum foil or copper foil.
Film coating: Pour the slurry into the open tank of the film coating machine , and spread the slurry on the surface of the aluminum foil or copper foil with proper pressure and speed until the entire surface is covered. During the coating process, care should be taken to maintain a uniform thickness of the coating to avoid voids and air bubbles.
Curing coating: According to the requirements of the slurry , the coating is subjected to necessary curing treatment, such as natural curing, heating curing, ultraviolet curing, etc. Make sure that the coating can be firmly attached to the surface of aluminum foil or copper foil, and not easy to fall off or peel off.
