In addition to electrolyte, the main materials of lithium ion battery also include cathode material, cathode material and diaphragm. The lithium battery pack diaphragm has good mechanical performance, chemical stability and high temperature self closing performance, so it can improve the comprehensive performance of the lithium ion battery in terms of isolating the positive and negative electrodes of the battery, allowing lithium ions to pass through, preventing battery explosion caused by high temperature, etc., thus making the lithium ion battery more advantageous than traditional lead-acid and nickel cadmium batteries in terms of energy density, cycle life, environmental protection and safety, It also enables lithium ion batteries to replace traditional lead-acid and nickel cadmium batteries, which are widely used in new energy vehicles, energy storage power stations, electric bicycles, electric tools, aerospace, medical and digital electronic products and other fields. Therefore, the lithium battery separator has become one of the key materials in the production of polymer lithium ion batteries, and even an important part of its industrial chain.
Rapid growth of demand
According to the data of China Automobile Association, in June, the production and sales of new energy vehicles in China were 86000 and 84000 respectively, up 31.7% and 42.9% compared with the same period last year; From January to June, the production and sales of new energy vehicles in China were 413000 and 412000 respectively, up 94.9% and 111.5% over the same period last year; Among them, the production and sales of pure electric vehicles were 314000 and 313000 respectively, up 79.0% and 96.0% over the same period of the previous year; The production and sales of plug-in hybrid vehicles were 100000 and 99000, respectively, up 170.2% and 181.6% year on year. Based on the growth rate of production and sales of new energy vehicles in the last half year, it is a big probability that the production and sales of new energy vehicles in China will exceed 1 million this year. The three-year Action Plan for Winning the Battle of the Blue Sky proposes that by 2020, the production and sales of new energy vehicles in China will reach 2 million, which also means that the annual growth rate of production and sales of new energy vehicles in China will exceed 30% in the next two years. It is conservatively estimated that each vehicle needs 50KWh of batteries and 0.01-0.02 square meters of battery separators per Wh of batteries. In 2018, China's new energy vehicles alone will need 5-10 billion square meters of lithium battery separators, while by 2020, it will need 1-2 billion square meters of lithium battery separators. The growth potential of lithium battery separators is amazing.
However, because the production process of the diaphragm has a high technical barrier, its cost accounts for 10% - 20% of the cost of lithium ion batteries, and its gross profit rate can reach 50% - 60%. It is the product with the highest gross profit rate among the four major materials. Therefore, the lithium battery diaphragm is also considered by the lithium battery manufacturers as one of the industries with the most investment value in the lithium ion battery industry chain.
