The plasma surface treatment device improves the specific properties of the surface of the PTFE material for lithium batteries

The plasma surface treatment device improves the specific properties of the surface of the PTFE material for lithium batteries:
The electric lithium battery is a commonly used lithium battery, which is driven by the display of the pneumatic tool. It is a clean and environmentally friendly power supply. At present, it has been widely used in pure electric vehicles, electric trains, electric vehicles and other fields. In recent years, with the rise of the new energy vehicle sales market, the safety and reliability of power lithium batteries has become a focus of attention and discussion. This is not only because the power lithium battery is a key component in the power drive system software, but also because the power lithium battery production process itself has high reliability and reliability requirements. For example, for lithium batteries for automobiles, what role can the plasma surface treatment device play in the production and manufacture of power lithium batteries? How can I help?
When the plasma etching temperature is low, the etched object is transformed into the gas phase. A mechanical pump is used to discharge the excess product, and the surface is continuously covered with fresh gas, so that the corroded part is not covered by the material (for example, chromium is used as a covering material in the industrial production of semiconductor materials). Plasma methods can also be used to corrode plastic surfaces, ashing these compounds. It is very necessary to use advanced technologies such as POM, PPS and PTFE to corrode printed adhesive packaging. The low temperature plasma surface treatment machine device can greatly increase the wet area and improve the bonding ability of the material surface. In the production process of automotive power lithium batteries, the surface treatment of plasma surface treatment equipment is usually carried out from three aspects, namely, improving the lubricating properties of the ceramic film before coating the positive and negative plates; cleaning the connecting piece before lithium welding; Improve the surface adhesion of insulating plates, end plates, PET plastic films and other metal composite materials and their insulating materials before gluing them and their lithium battery components. Next, I'll give a brief summary of this and go into detail one by one.
Based on the positive and battery cathode materials of the ceramic film, the positive and negative stages of the automotive power lithium battery were prepared. Compared with cleaning with aqueous solutions such as ethanol, the plasma surface treatment device not only does not destroy the raw materials, but also can remove organic substances on the surface of the raw materials, improve the lubricity of the film surface, improve the uniformity of the coating, and improve the heat resistance and safety of the coating. coefficient. Plastics, laminated glass and ceramics are often used in daily necessities due to their excellent properties and low prices. Fluoroplastic materials have important application prospects in some special industries due to their excellent organic chemical properties, excellent dielectric properties, extremely low frictional resistance and bearing self-lubrication. However, during the entire release process of this material, it is difficult to avoid the problem of weak adhesion between the same material or between the same material. To this end, we discuss the reasons for the non-bonding of such non-bonding polymers and the surface solutions. Plasma surface conditioner units are not prone to damage to samples. In addition, all surface problems can be solved very uniformly, and harmful substances are not easily generated. Hollow products can also be processed, which is environmentally friendly, requires less indoor space during work, and has low cost. The actual effect can be solved by simple plasma identification according to the hydrophilicity, and the problem of whether the surface of the sample is completely soaked can be solved.
The lithium tab actually refers to the correct guide of the metal material strip between the positive and negative electrodes of the rechargeable battery. It is a point-contact type when charging and discharging. Whether the surface of the bonding plate is clean or not directly affects the reliability and performance of electrical bonding. Using a plasma surface treatment device before electric welding can remove the residual organic matter and particles on the surface of the welding seam, making the surface of the welding seam uneven, thereby improving the welding quality. The two gases are brought together so that they enter the reaction chamber during the smearing process, where they polymerize in a plasma environment. The cleaning method used is more stringent than plasma surface cleaning. The coating is easy to maintain and only 1 micron. General criteria include waterborne coatings similar to PTFE material coatings designed to avoid crossover with their hydrophilic coatings.
The assembly process of a lithium battery is to connect several rechargeable battery modules in series into a series of parallel circuits to form a lithium battery pack. In order to ensure the safety of the power supply line and the insulating layer, the rechargeable battery must be attached to the outside during use to improve the safety factor of the application. Before, please use a plasma cleaner to clean parts such as insulating plates, end plates, PET films, etc. Plasma surface treater device treatment can thoroughly clean the dirty surface, make the surface matte and enhance the adhesion of super glue or super glue. The surface layer of metal materials is usually an organic chemical layer and a hydroxide layer, such as grease, vegetable grease, etc. In magnetron magnetron sputtering, painting, bonding, arc welding, soldering, and PVD, CVD and other coating processes, plasma cleaners must be used to obtain a clean and non-reducing surface layer.
ptfe should not be used for packaging, printing or pasting without proper treatment. The use of alkali metals can increase suction, but this method is difficult to master, and the solution is harmful to the human body. The use of the plasma cleaning machine can not only protect the environment, but also achieve a good practical effect. The PTFE mixture must be handled with care to prevent excessive filler exposure. Plasma surface treatment equipment can amplify the surface effect, so plastics can be glued together for packaging and printing. After several years of development, the power lithium battery industry chain has initially formed, but there are still problems such as insufficient technical strength and R&D capabilities, and can not be fully utilized. It is believed that with the improvement of technical standards, the requirements for plasma surface treatment equipment will be more detailed and diversified.
