Introduction of lithium battery pole roll mill

The Nakonor company produced and launched the pole roll mill since 2005. However, in just five years, the company has been able to compete with lithium ion battery equipment manufacturers in Japan, the United States and other countries. At present, the company has established sales relations with almost all major domestic battery manufacturers and has achieved some exports. The largest specification 800 pole roller mill domestic market share reached about 90 %. Last year, it sold more than 100 units with an output value of more than 100 million yuan.

With the rapid growth of lithium-ion battery applications and markets, it is inevitable that the demand for productivity and product quality will be higher. In recent years, the company has continuously developed new products. The second is to make the precision of the product more reliable. In order to improve the accuracy of the product, the company has independently developed a set of hydraulic servo control systems since 2005. This system cooperates with the automatic thickness measurement system to achieve full automatic control of the thickness of the rolling pole. At present, the system has obtained a number of national patents. License, And installed on part of the mill.

Since the development of this system, the consistency of the production of polar films has been fundamentally improved, and the product pass rate has been significantly improved. At present, this kind of mill has ensured that the thickness error of the polar film is controlled within 2 microns, which is completely comparable to Japanese equipment..

At present, China has become the world's second largest producer of lithium batteries. The survey shows that with the gradual increase in the heat of new energy vehicles, the market for lithium batteries for vehicles will also expand rapidly, and the market size will expand by more than 200 times within five years. The requirement for product consistency in automotive power batteries is much higher than that in consumer electronic equipment. If the consistency problem is not solved, the produced iron-lithium battery can not be applied to electric vehicles on a large scale. Market demand for battery production equipment manufacturers put forward higher requirements. Gengjianhua admits that although the company has grown rapidly by more than 50 % each year in recent years, the pressure is still great because it is only through continuous innovation that it can maintain its technological leadership.
