The function of lithium battery diaphragm is the real leader of high-end lithium battery diaphragm.

In our daily life, electric cars will catch fire, so the batteries of electric cars must pass the quality inspection. Nowadays, batteries are generally high-end lithium batteries, which can better reduce the occurrence of fire in electric vehicles. So, today I will share with you the real leader of the high-end lithium battery separator. At the same time, let's talk about the function of lithium battery separator. Let's take a look at the relevant knowledge.

1, * ST victory:

The total share capital is 344,200 shares, and there are 294,300 A shares in circulation, with earnings per share of 0. 1 146 yuan.

Domestic leading manufacturers of lithium battery separators are expected to cut into Tesla supply chain.

2. The sky is changing:

Total share capital 183700 shares, A shares 136 10000 shares in circulation, with earnings per share of 0. 1902 yuan.

In August 2009, Yuntianhua invested 654.38+0.2 billion yuan to build a modified engineering plastic project in Chongqing R&D Center, and developed a production line of 654.38+0.5 million square meters/year for wet lithium battery diaphragm. The lithium ion battery separator project with an annual output of 6,543.8+500,000 m2 was officially put into production in June, 2065.438+02, and became a domestic product.

3. Park Tae Lai:

The total share capital is 49,600 shares, with 44,400 A shares in circulation, and the earnings per share is 1.5200 yuan.

Putailai plans to acquire 66.67% equity of Liyang Yuequan for 262 million yuan to realize full control. Liyang Yuequan Electric Energy Co., Ltd. is mainly engaged in multifunctional polymer microporous membrane (that is, lithium battery separator), which is one of the four major materials for lithium ion batteries. The management team of Shanghai Yuequan, a wholly-owned subsidiary of Liyang Yuequan, is one of the earliest teams engaged in the production of wet separators in China, and has accumulated rich industry experience and profound related technology accumulation in the field of wet separator products.

Function of lithium battery diaphragm

The separator is one of the key components of lithium battery. The main material of the separator is porous polymer membrane, including polyethylene and polypropylene. Lithium battery separators have strict requirements on safety, permeability, porosity and thickness.

In a lithium battery, charged ions flow and shuttle between the anode and cathode to form current, and the diaphragm is located between the anode and cathode in the battery, which not only prevents the anode and cathode from directly contacting, but also ensures the smooth passage of electrolyte ions. Lithium battery electrolyte is like a river, lithium ion is like a boat sailing on the river, the diaphragm is the dam in the middle, and the diaphragm hole is like a gate on the dam. Under normal circumstances, ions freely shuttle between the positive and negative poles to complete the cycle of charge and discharge.

The above is the real leader of the high-end lithium battery diaphragm that I shared with you today, and I also shared the relevant knowledge about the role of lithium battery diaphragm, hoping to bring you help. At present, the separator is a high value-added material with the highest technical barrier among lithium battery materials, accounting for about 15% of the cost of lithium batteries. It is a relatively good lithium battery at present and has great functions. You can refer to this article to learn more about lithium batteries.
