A new round of expansion has lithium batteries, industrial control automation enterprises can greatly

Although the new energy power battery industry after rounds of & other; Shuffle the deck & throughout; , but the power battery with high quality in short supply situation is still in for a long time. According to China's chemical and physical power industry association ( CIAPS) Statistics, China's lithium battery production growth in 2018 to 124. 2 billion watts, year-on-year growth of 23. 1%. The rapid expansion of the lithium battery market, mainly from the growth of new energy vehicle power battery; Among them, 2018 power lithium battery production reaches 65 billion watts, year-on-year growth of 45. 7% ( As shown in figure 1) ； And throughout the new installed capacity of power battery, battery for three yuan 33. 1 billion watts, the total installed capacity of 58. 2%; Lithium iron phosphate battery for 221. 900 million watts, accounting for 39% of the total installed capacity. Figure 1:15 In 2018 China's power lithium battery production statistics ( Source: CIAPS) From the perspective of overall global industrial chain, new energy vehicles power lithium battery market increasingly competitive, since 2018, to Japan, Korea, as a representative of the major manufacturers have increased the investment of construction scale, especially in China's new energy automotive industry are the most active market, power lithium battery in the last two years the giants are orderly expansion of their capacity layout ( See table 1) 。 Table 1 each big manufacturer under construction and plans to build power battery production line when it comes to the recent development of Chinese power battery industry status quo, CIAPS association secretary-general yan-long liu said that by 2018 China subsidies slump, energy density and power battery industry momentum threshold increases significantly and enterprise capital chain tension, multiple pressures, the market has entered the fast & other; Shuffle the deck & throughout; Phase, on the one hand, enterprises to expand production scale, on the other hand is to improve the automation level of production line, improve the yield of product consistency and. Under this trend, for the industrial chain upstream of the lithium electricity equipment industry has provided a broad space for development. According to statistics, in 2018 four listed lithium electric equipment enterprise total revenue rose 22. 47%; Buckle the female net profit fell 15. 58%, in the industrial chain is affected by new energy vehicle subsidies TuiPo minimum. Lithium electric equipment industry in 2019 is expected to continue to maintain high growth, especially thanks to foreign leading companies in the domestic factories, nearly two years of lithium electricity equipment demand will grow larger, and profit growth of lithium electricity equipment enterprises in 2019. 1 lithium electric equipment industry for the development of new trend around the power battery, has become the present stage to promote the new energy automobile to popularize and apply a focus, aims & ndash; — High energy density, low cost, high safety, therefore, in addition to the optimization of material system and manufacture craft fluctuation kongfu, the development of lithium battery production equipment is also a very important link. Currently one of the more obvious trend is that the lithium battery production equipment renovation and upgrade the whole production line speed, integrated equipment be favorred by the application side, in order to meet the mainstream power lithium batteries urgent request of the authors and effect of the enterprise. For example, the forerunner intelligence can be developed a new type of laser cutting winding machine instead of traditional die-cutting machine ( 2) And winding machine ( 1) , on the one hand, the precision of the laser cutting than traditional die-cutting greatly increased; On the other hand, the laser cutting of the winding machine capacity & ge; 100 m/min, saves space and manpower cost, also save the handling process between the die cutting to the winding, and improve the production safety. In addition, the forerunner of intelligent latest high-speed lamination machine, its precision can reach & plusmn; 0. 2 mm, to achieve the domestic advanced level. New energy automobile power lithium batteries of the entire production process, generally can be divided into electrode production ( The front) , batteries assembly ( In the middle) And after the treatment ( After paragraph) The three major process ( As shown in figure 2) 。
