Etching Helps The New Energy Battery Industry

After the "Government Work Report" of the two sessions in 2021, China promised to achieve carbon peak by 2030 and carbon neutrality by 2060. Under the guidance of the trend, the prospect of new energy development is very promising. With the development of the field of new energy vehicles, a mature and complete industrial chain has gradually formed. The power battery is an important part of the new energy vehicles, and plays a decisive role in the key indicators such as mileage, vehicle life and safety.

The new energy vehicle is composed of hundreds to thousands of small pieces of batteries, which form a battery pack with a length of 2 meters, a width of 1.4 meters, and a height of 25 centimeters. The mileage of new energy electric vehicles depends on the number of battery packs, which is known as blade batteries. Tesla models basically use Panasonic‘s ternary lithium battery, while BYD uses the self-developed blade battery, its predecessor is lithium iron phosphate battery.

In the field of new energy vehicles, the etching process can be considered to be completed in the process. The main reason is that the etching of new energy batteries under high precision and strict tolerance can well guarantee the product characteristics and help to better play the stability of new energy vehicles. The heating film of automobile lithium battery is also completed by etching, and the difficulty coefficient of machining is relatively high. The metal foil and wire contained in the heating film of automobile ensure the material properties, stress and hardness by etching. The etching method has higher convenience and lower cost advantages compared with other processes in terms of research and development and batch revision costs.
