Brief introduction of lithium ion battery barrier unit price

Among the production costs that make up the barrier of lithium-ion batteries, the largest part of the cost lies in equipment depreciation and labor costs, which account for nearly half. The important raw materials polyethylene, methylene chloride and white oil account for about 30%. Gas accounts for about 20%. In the same period, the unit prices of base film semi-finished products were 3.76 yuan/square meter, 3.85 yuan/square meter and 3.04 yuan/square meter, a decrease of 19.15%; product unit prices were 4.13 yuan/square meter, 4.3 yuan/square meter and 4.12 yuan/square meter Meter. The unit price of base film for 2015-2016 and January-August 2017 is 4.29 yuan/square meter, 4.02 yuan/square meter and 3.82 yuan/square meter; the unit price of coated film for 2016 and January-August 2017 is 6.82 Yuan/square meter and 6.08 yuan/square meter, the decline is 10% higher. Through ceramic coating technology, wet barriers can fully surpass dry barriers in terms of thickness, through-hole characteristics, security and other functions. The combination of wet barriers and ceramic coating will also become an important bias for future barrier growth. The focus of coating skills is the formulation of the coating slurry. The coating slurry mainly includes ceramic particles, binders, solvents and additives. There will be different material ratios according to different downstream utilization scenarios. The innovation of coating skills will also greatly enhance the focus of the company's competitiveness. Due to the outstanding advantages of wet barriers and the performance can be improved by coating methods, wet barriers have grown rapidly in my country for years. In the past two years, there has been strong demand for the wet process barrier, and the supply is not enough. In terms of value, with the continuous release of production and continuous improvement in technology, the barrier value of lithium-ion batteries has been declining for years. In the first quarter of 2018, the average prices of wet process barriers, dry process single pull barriers, and dry process double pull barriers were 2.9 yuan per square meter, 1.9 yuan per square meter and 1.5 yuan per square meter. It can be seen from the trend of output and output that the wet process will be an important force for the future industry, and its market share will continue to increase. The survey data shows that the current value of my country's wet base film is 2.2 yuan/㎡, the value of dry single-pull base film is 1.6 yuan/m2, and the value of dry-type double-pull base film is 1.3 yuan/m2. With the gradual promotion of the equivalent of each company, the limiting effect gradually becomes prominent, and the cost is low, which will be conducive to the subsequent market advancement. The industry’s initiative is that the decline in gross profit is a current trend that cannot be vetoed. The company must continue to improve and improve the production process of lithium-ion batteries, reduce product costs, and increase product yields to cope with value changes.
