On May 18, the market price of diaphragm in many regions showed an upward trend. Baichuan Yingfu data show that the price of 16um wet process in Henan and Jilin rose to 1.33 yuan / square meter, an increase of 0.01%. In addition, the price of 16um wet process in Shenzhen rose to 1.335 yuan / square meter for three consecutive days.
Most experts interviewed by the reporter of Securities Daily believe that benefiting from the rapid growth of the new energy vehicle industry, the value of its relevant industrial chain is gradually highlighted. As a material with ultra-high added value in power battery, diaphragm has the characteristics of high technical barriers and outstanding growth value.
estimated diaphragm demand of nearly 10 billion square meters
According to the data of Longzhong information, from 2017 to 2021, the shipment volume of China’s diaphragm market increased from 1.64 billion square meters to 8.06 billion square meters. In 2021, the shipment volume of diaphragm increased by 108.27% year-on-year. It is expected that the shipment volume of power battery will reach 470gwh in 2022, and the demand for diaphragm will be nearly 10 billion square meters.
“Diaphragm is one of the important components of power battery. Its performance directly affects the specific capacity, cycle times and safety performance of battery.” Chen Li, chief economist and director of the Research Institute of Chuancai securities, told the Securities Daily that with the rapid development of the new energy industry and the rapid growth of the demand for power batteries, the scale of diaphragm shipments in China will continue to expand, and the simultaneous rise of volume and price will help further improve the scene of diaphragm market.
At the same time, diaphragm prices in many regions showed an upward trend.
The relevant person in charge of Baichuan Yingfu told reporters that since 2022, the supply-demand relationship of diaphragm in China has gradually changed to short supply. The rapid growth of power battery output has driven the sharp rise of diaphragm demand. However, the production capacity of Chinese diaphragm enterprises is limited, and the supply can not meet the demand. The balance point of the industry needs to be assessed from two aspects: supply and demand. With the gradual easing of equipment supply and the release of new capacity, the supply of diaphragm is expected to increase in 2024, and the market price of diaphragm in China may rise slightly in the short term.
China Securities Co.Ltd(601066) securities research report pointed out that it is expected that the price rise tide of China’s diaphragm will further spread in 2022, and the price will remain high until 2024.
several listed companies are optimistic about the diaphragm Market
Affected by the continuous improvement of industry prosperity, many listed companies are actively optimistic about the diaphragm market.
Recently, Cangzhou Mingzhu Plastic Co.Ltd(002108) said on the investor interaction platform that the sales target of the company’s diaphragm products in 2022 is 286 million square meters, which is expected to increase compared with the previous year. In addition, the average sales price of wet diaphragm products in the first quarter of this year has also increased compared with last year, and the “simultaneous rise of volume and price” will play a positive role in the company’s performance.
Malion New Materials Co.Ltd(300586) said that two production lines of Anhui Meixin lithium battery wet diaphragm project, a subsidiary of the company, have been put into operation. It is expected that two production lines will be completed and put into operation in June, and the annual production capacity will reach 300 million square meters at that time.
In addition, lithium battery separator giant Yunnan Energy New Material Co.Ltd(002812) 5 announced on May 5 that in order to speed up the overseas market development of the company’s lithium battery separator business, it will invest in the construction of a lithium battery separator factory in Sidney, Ohio. The plant plans to build a base film production line and supporting coating equipment of 1-1.2 billion square meters, with a total investment of US $916 million (about 6.15 billion yuan).
“Out of optimism about the new energy industry chain, listed companies increase capital and expand production, and even cross-border layout of diaphragm industries.” Qi Haizhen, President of Beijing Teyi Sunshine New Energy Technology Co., Ltd., said in an interview with the reporter of Securities Daily that the products of head diaphragm enterprises are in short supply, and Yunnan Energy New Material Co.Ltd(002812) and other relevant enterprises will usher in deterministic market development opportunities.
Chen Li believes that China’s diaphragm market is constantly concentrating on leading enterprises. As a technology intensive industry, diaphragm production and manufacturing has high requirements for enterprise equipment, improvement ability and process control ability. It is necessary to improve the quality, production efficiency and yield of diaphragm products through continuous development, commissioning and improvement.
