The application of plasma cleaning in power battery -- Atv plasma cleaning machine

New energy power battery

There are many types of new energy power batteries, which can be divided into chemical, physical and biological batteries according to the type. From the perspective of structure, it can be divided into two categories: battery and fuel cell. From the type point of view, the batteries used in new energy vehicles are chemical batteries, usually lead acid, lithium titanate, lithium cobalt, lithium iron phosphate, nickel cobalt, nickel cobalt aluminum five kinds of power batteries.

Among them, lithium iron phosphate batteries with high energy density and more stable performance and ternary lithium batteries are the two most widely circulated batteries in the current power battery market, and are also the most widely used main power sources in electric vehicles.

Power battery production technology

Cap/top box welding: If there is dirt and dust invisible to the naked eye on the surface of the battery cell, it will lead to false welding during welding, which has a great impact on the reliability and durability of the battery cell. Therefore, plasma cleaning must be carried out before cap welding/top box welding, which can remove impurities such as organic matter or small particles on the surface and prepare for welding in advance to reduce bad welding products.

Power battery production process

The use of plasma treatment before the cell coating can completely clean the surface of the cell, coarser the surface of the cell, and improve the adhesion of the subsequent coating.

Why is the power battery concerned?

Industry analysts believe that the acceleration of the pace of expansion of power battery companies is mainly based on the support of market demand, the rise of the new energy vehicle market, and the market demand for power batteries is also increasing. "The huge market space and growth potential, as well as the industry position of power batteries as the core of electric vehicles, have stimulated the outbreak of automotive power battery circuits."
