PE battery separator is a product that can effectively reduce air pollution inside the car and protect passenger health

With the development of society, people's awareness of environmental protection is increasing day by day. In order to reduce environmental issues, electric vehicles are becoming increasingly popular among consumers. (取决于上下文，如"but"Battery film PE battery separatorIt is a product that can effectively reduce air pollution inside the car and protect the health of passengers.

1: Characteristics of PE battery film

PE battery film is a composite film mainly composed of cellulose acetate (CA) and natural rubber (GSLA). Among them, cellulose acetate has the characteristics of sodium salt: 1 Its melting point is relatively low, between 40-50 nanometers; 2. Good water resistance and not easily affected by external environmental factors; 3. Non toxic and odorless; 4. Has good insulation performance; 5. Easy to be compatible with other materials. In addition, cellulose acetate also has many excellent properties, such as wear resistance, impact strength, and strong adhesion. Due to its excellent properties, cellulose acetate is widely used as a separator material in lithium batteries.

2: Common materials and their advantages and disadvantages

Lithium battery separator is a porous thin film typically composed of multiple layers of membranes. Its main advantages include: - effectively reducing battery costs - compared to traditional double-layer separators, it reduces material and processing costs- Smaller design size - due to its large surface area, it has higher strength- Good corrosion resistance - easy to clean and regenerate - good long-term stability, etc. However, lithium battery separators also have some drawbacks, such as limited temperature range, easy water absorption and expansion, and difficulty in waterproofing and moisture resistance. If you want to choose a suitable lithium-ion battery separator, you can consider the following factors: - Thickness: The thicker the separator layer, the more susceptible it is to impact and damage. 2. Breathability: The thinner the membrane layer, the lower the air permeability and the less durable the membrane. 3. Performance: The performance of the diaphragm depends not only on the material, but also on the manufacturing process. 4. Lifespan: As the diaphragm ages, it will become unstable, and its service life will be shortened or even fail.

3: How to choose the appropriate lithium battery separator

Lithium ion battery separator is a special membrane that can transfer the heat generated in the lithium-ion battery to the other end. Choosing the appropriate lithium battery separator also requires consideration of many factors, including materials, processes, and structural design. For example, if you want to use a shrink film, you should choose polyester film or epoxy resin film; If you want to reduce energy loss, you should choose thicker composite materials; In addition, the required size or thickness should be determined based on the actual situation. Another important factor to consider is durability. Due to the fact that PE battery films are usually not durable, special attention should be paid when selecting them. Generally speaking, in order to extend its service life, it is necessary to reinforce it. Once a malfunction occurs, replacing the PE battery film with a new one may require a significant amount of time and money.

Therefore, PE battery separators will be more widely used in the future. We look forward to the maturity of electric vehicle technology, and also hope that PE battery separators can bring us a better life.
