Power battery is used for new energy vehicles to provide power for the battery, power battery for the general battery technology requirements, higher requirements for the sustainability of the battery, at present, the domestic power battery manufacturers are everywhere, on the surface of the comprehensive development, a good scene. Power battery pack liquid cooling radiator experts believe that the power battery pack industry will blossom from everywhere to the situation of polarization transformation, in a period of time, the polarization of power battery enterprises is significant, leading with leading pattern is basically determined.

Throughout the development of domestic power batteries, battery production capacity is rapidly expanding, which leads to the overall continued surplus of domestic lithium batteries. From the quality point of view, inferior production capacity is more, high quality production capacity is still insufficient, the concentration of power battery industry will be further improved, will be concentrated to high quality and high standard of enterprises, popular models supporting manufacturers are mainly concentrated CATL, BYD, Guo Xuan, Force God, Fu Neng and other first and second line power battery leading enterprises.

Looking to the future market, the structural surplus will be maintained for a long time, the scale effect and technological breakthrough of leading enterprises will achieve a steady decline in cost, profit margin will have a good performance, while the middle and low-end battery enterprises will face great pressure of reshuffle. How to survive in the competition has become the power battery enterprises must think about the problem.

Process technology is very important for power battery. Power battery preparation will develop to scale and intelligence, improve product consistency and yield, which is a key point to improve quality. The mass production and intelligent manufacturing transformation and upgrading of power batteries can also be regarded as the window of quality breakthrough.

Power battery enterprises with good technology and process will be targeted by important domestic and international car enterprises, especially leading enterprises, which have basically met the conditions for mass production. Large-scale intelligent production equipment can through digital means, the introduction of big data analysis and the principle and method of artificial intelligence, improving the quality of products at the same time realize the capacity of statistics and product basic diagnostic and traceability, finally realizes the comprehensive monitoring of battery production process, effectively solve the consistency problem of poor and low yield of battery. Power battery pack liquid cooling radiator experts believe that this needs to spend a lot of money on technical equipment update and continuous improvement in the process, which is also a test of the strength of power battery enterprises.

Globally, the output of power batteries is mainly concentrated in China, Japan and South Korea, with Japan and South Korea taking the lead in technology for the time being, and Chinese enterprises are expected to catch up in the future. Industry giants mainly include Samsung and LG Chem from South Korea, Panasonic, ASEC and SONY from Japan, and BYD and CATL from China. From 2016 to 2017, domestic battery manufacturers are in the trend of full-line production expansion. By 2020, the national effective capacity will be mainly three, and the top five power battery enterprises will occupy more than 80% of the market share.

Although Japan and South Korea power battery enterprises are ahead of China in technology, but Chinese enterprises' technology quickly catch up and cost advantage highlights. At present, the four major raw materials have all been independently, the positive electrode and diaphragm with the highest barrier have begun to export, the key equipment of lithium has been independently, and the leading intelligence has begun to export. CATL has entered the supply chain of BMW and other first-class automotive enterprises. It can be predicted that there will be 2-3 global leading power battery brands in China to seize global market share. Experts believe that especially in the field of high-end power battery, the cost advantage of Chinese enterprises will be further highlighted.
