Lithium battery separator technology helps electric vehicles -Lithium - Ion Battery Equipment
On July 29, CCID Consulting released the "White Paper on my country's Lithium Battery Separator Industry (2015)" (hereinafter referred to as the "White Paper"). The white paper studies the market size and competition pattern of the global and my country's lithium battery separator industry in detail, and evaluates the competitiveness of my country's lithium battery separator companies through comparative analysis of various indicators. On this basis, the "white paper" also predicts The development trend of lithium battery separator in the future.(Lithium - Ion Battery Equipment)
According to reports, as a research institution directly under the my country Electronic Information Industry Development Research Institute of the Ministry of Industry and Information Technology, CCID Consulting has long been focusing on the research on the new energy vehicle industry chain, and has written and completed the "White Paper" on the basis of extensive research.
The "White Paper" revealed that benefiting from the drive of downstream new energy vehicle batteries, the overall output of the global lithium battery separator industry in 2014 was 1.185 billion square meters, with an output value of US$2.075 billion, up 41.58% and 12.18% year-on-year respectively. As far as the Chinese market is concerned, the national diaphragm output in 2014 reached 575 million square meters, accounting for about 48% of the global output, with an output value of 2.05 billion yuan. In the next few years, my country will remain the world's largest producer and consumer of lithium batteries. CCID Consulting predicts that by 2018, my country's small lithium battery shipments will reach 7.55 billion. In addition, the Korean market will also maintain an increase of about 10%, while the Japanese market will basically maintain a stable and declining trend.
The "White Paper" points out on the basis of a detailed study of the global and domestic diaphragm industries and companies that the future competition in the diaphragm industry will focus on the competition of wet-process diaphragm products. The "White Paper" believes that my country is still in the early stage of import substitution in the field of wet process diaphragms, while in the field of dry process diaphragms it is relatively mature, the competition is more intense than that of wet process, and it can basically completely replace imported diaphragms. downward pressure on prices.
According to reports, the future development direction of the diaphragm industry is three aspects: thinning, coating technology and matrix materials. The thinner the diaphragm, the more electrode material can be accommodated in a small volume, and the diaphragm coating technology can keep the integrity of the diaphragm after a large area of heat is released during the charge and discharge process, which is a good solution to the heat resistance of the diaphragm. Worse problem, ensure safety. The development and application of new materials will provide feasible solutions for the safety of high-power power batteries. The dry method diaphragm is thicker than the wet method diaphragm, but the dry method yield (60%-70%) is higher than that of the wet method (50%). Globally, this figure is 80%.
At a time when the country is vigorously promoting the development of the new energy vehicle industry, the "White Paper" released by CCID Consulting pointed out that at present, about 30% of my country's electric vehicle OEMs use domestic diaphragms in power lithium batteries. In the next few years, lithium batteries will be more used in the field of electric vehicles. Due to the explosion of the electric vehicle market, the lithium batteries used as power will show a doubling trend. CCID expects that by 2018, the global shipments of medium and large lithium batteries will exceed 400 GWh, reaching 425.5 GWh. watt hours.
In addition, in the next few years, the global electric vehicle market, especially in my country, will still be dominated by policies. CCID Consulting predicts that after 2020, policy factors will gradually fade in the electric vehicle industry, and the entire electric vehicle and its power lithium battery market It will return to the normal rate of increase, which is expected to be an average annual increase of about 50%. The policy subsidy is relatively large for pure electric vehicles with a short driving range (100≤R<150), and further increases the driving range requirements for electric passenger vehicles.
