Lithium-ion battery separator
is polypropylene (PP), polyethylene (PE), or trilayer PP/PE/PP electrolytic separator membranes which plays a critical role of separating the cathode from the anode. It is this separation of charge that allows the battery to generate electricity. It is widely used in consumer electronics, power vehicle, electric power storage, etc.
The lithium battery cell, where Lithium-Ion Battery Separator are widely applied, is composed of cathode material, anode material, electrolyte and separator, of which, lithium-ion battery separator as a high value-added material with the highest technical barrier among lithium battery materials accounts for about 15-20% of the battery cost. The main role of the separator film is to separate the positive and negative electrodes of the lithium-ion battery, thus preventing two neighboring contacts from a short circuit.
As new players continue to be attracted to the market by high gross margins, excessive price competition has caused prices to continuously fall.
By the year of 2025, global sales of Li-Ion Battery Separators will be about 20342.6 million sqm, growing from 4433.5million sqm in 2018 at a CAGR of 24.31%. Correspondingly, global revenue is to reach 13113.28 million USD in 2025, from 4815.30 million USD in 2018, with a CAGR of 15.39%.
The downstream of the lithium-ion battery separator is rigid, which is wildly used in the consumer electronics, power vehicle, electric power storage and industrial use etc. fields. Consumer electronics field was the major field which account for approximately 51.28% in 2018, but will soon decline to 26.99% in 2025, when Power Vehicle will take the biggest part of the market (61.68%).
From the type perspective, compared with Dry Method Li-Ion Battery Separators, the Wet Method Li-Ion Battery Separators sees a rising tendency these years as it as it boasts off higher stability, permeability and thinness. Against the growing demand for Wet Method Li-Ion Battery Separators, Chinese Dry Method Li-Ion Battery Separators manufacturers are expanding their investment on Wet Method Li-Ion Battery Separators production aggressively, let alone the Wet Method Li-Ion Battery Separators manufacturers. Wet Method Li-Ion Battery Separators, taking up about 53.21% of the sales market in 2018, will reach about 13220.6 million sqm in 2025, with a CAGR of 28.28% during the forecast years.
According to the country, Chinese manufacturers account for 55.46% of global sales, Japan accounts for 20.67%, and South Korea accounts for about 15.75%.
More importantly, the growth rate of Chinese manufacturers is faster than that of Japan and South Korea, that is, China’s share of the world Li-Ion Battery Separators sales continues to increase. Thus, by the year of 2025, China’s sales share is estimated to reach about 82.39%.
Obviously, China, Japan and South Korea will be the largest production and consumer markets in both the present and the future; with which Europe and North America, however, are difficult to compare in a short period of time.
