The demand for the hottest flexible power battery

There is a strong demand for flexible power batteries, and the localization rate of aluminum-plastic film is less than 10%

according to statistics, in 2016, China's power battery production capacity reached 30.8gwh, of which flexible batteries accounted for 12%. With the continuous development of battery technology, the penetration rate of flexible battery in the new energy vehicle market is expected to exceed 50% in the future. At present, a number of enterprises producing soft pack batteries, including Yiwei lithium energy, Penghui energy, Tianjin Co., Ltd., Tianjin Jiewei, Beijing Guoneng, etc., have made clear their plans for investment and expansion. Nowadays, the new energy vehicle market continues to be booming, and the power battery field shows a high-speed development trend. The market competition is increasingly fierce. In the development of power battery industry, flexible battery has become an important choice for the technical route of power battery because of its good safety performance, light weight, large capacity, small internal resistance and other advantages

domestic soft pack battery enterprises accelerate the investment and expansion of production

the demand for aluminum-plastic film continues to strengthen

as the main material for packaging soft pack batteries, with the continuous expansion of 3C and power battery market, the market demand also continues to strengthen, and many enterprises begin to focus on the field of aluminum-plastic film. According to the data of industry institutions, the demand for aluminum-plastic film for lithium batteries in China in 2016 (excluding factories of foreign-funded enterprises in China, except ATL) was 95million square meters, an increase of 44% year-on-year; Among them, the domestic output of aluminum-plastic film is 4.94 million square meters. Domestic aluminum plastic film accounts for only 7%. This means that there is still a huge import substitution market to tap in the field of aluminum-plastic film

at present, Daoming optoelectronics, Zijiang new materials, Xinlun technology, from the oil spill and other exports, we can see that enterprises such as sudanhuicheng, Dongguan Zhuoyue, Zhuhai Saiwei, fosu technology, mingguan new materials, Lianyungang Shenyuan have entered the field of aluminum-plastic film

Zijiang Enterprises:

in 2011, Zijiang enterprises began to test sell aluminum-plastic film. In order to rapidly industrialize the aluminum-plastic film project, Zijiang enterprises stripped the aluminum-plastic film project from Zijiang color printing in 2012 and prepared to establish Shanghai Zijiang New Material Technology Co., Ltd

after years of research and development, Zijiang enterprises have developed aluminum-plastic film, the packaging material for soft packed lithium batteries. The products have passed a new material processing technology, and have gradually attracted more attention. TL, Guangyu, Lishen and other large lithium battery manufacturers have been certified, with independent intellectual property rights. In 2016, Zijiang enterprises further strengthened the research and development of new products such as lithium battery aluminum plastic film, and are striving for rapid mass production. In 2016, its digital and power customer structure of aluminum-plastic film products accounted for 9:1

According to the 2016 annual report of TONGCHAN Lixing, the company achieved an operating revenue of 1.057 billion yuan, an increase of 3.49% year-on-year; The net profit attributable to shareholders of listed companies was 26.2785 million yuan, an increase of 244.17% year-on-year

localization is imperative

although the current market demand is gradually increasing, power battery enterprises still have many concerns when choosing domestic aluminum-plastic film. They have used imported aluminum-plastic film products for a long time, which has been mature in product adaptation. In addition, they are also worried about the performance of domestic aluminum-plastic film products

although there is still a certain gap between domestic aluminum-plastic film and imported products, in recent years, domestic aluminum-plastic film enterprises have been constantly improving and updating in terms of materials, technology and equipment, and their product quality, product consistency, and electrolyte resistance have been qualitatively improved. At the same time, in the field of power batteries, many enterprises began to gradually accept domestic aluminum-plastic film products, and some domestic mainstream battery enterprises have begun to test and debug domestic aluminum-plastic film products

according to the prediction of insiders, the domestic market demand for lithium battery aluminum plastic film will reach 128.5 million square meters in 2017, and the domestic output will reach 12million square meters. The market share of domestic aluminum plastic film is expected to exceed 10% this year. In addition, the demand for aluminum-plastic film in 3C, energy storage and other fields will also continue to grow. It is expected that the total size of the domestic aluminum-plastic film market will reach 11.6 billion yuan by 2020

it is understood that the cost of aluminum-plastic film accounts for 15% - 20% of the cost of soft pack batteries. It is estimated that by 2020, the domestic demand for aluminum-plastic film will reach 300million square meters. For such a large market demand, it is imperative to reduce the cost of aluminum-plastic film

for this, Industry experts said: "Domestic aluminum-plastic film has five advantages: first, it has the advantage of cost performance, and the gap between domestic price and imported price is maintained at more than 20% - 30%; second, it is performance guarantee, and the key performance indicators have reached or even exceeded the level of imported brands; third, it is flexible sales strategy, market development channels are more direct, and the transaction mode is more flexible; fourth, it is perfect after-sales service, with sufficient supply, timely distribution, and more comprehensive and fast technical services; fifth, good after-sales service Guarantee, dare to take risks and eliminate customer concerns. "

for domestic aluminum-plastic film, even if there will be more difficulties ahead, it can not prevent domestic enterprises from moving forward. With the increase of import substitution rate market, it is expected that the technical level of domestic aluminum-plastic film enterprises will be further improved. Domestic aluminum-plastic film will speed up import substitution through cost advantages. In the future, the market space is large, and the performance and requirements of domestic aluminum-plastic film will be tested soon
