The application of adhesives in the field of new energy

The application of adhesives in the field of new energy is diverse and extensive, and can be classified according to different application scenarios.

1. Photovoltaic panel manufacturing

In the manufacturing process of photovoltaic panels, it is necessary to use adhesives to bond the silicon sheet and the glass substrate together, as well as to connect the battery sheet with the copper bar. Commonly used adhesives include:

Vinyl acrylate (EVA) adhesives: Excellent weather resistance and UV resistance.

Polyurethane adhesive: high strength and heat resistance.

Silica gel: has excellent weather resistance and chemical resistance.

2. Lithium-ion battery manufacturing

In the manufacturing process of lithium-ion batteries, it is necessary to use adhesives to bond the positive and negative electrode sheets to the diaphragm, and to seal the shell and the end cap. Commonly used adhesives include:

Polyurethane adhesive: Excellent bonding strength and chemical stability.

Epoxy resin adhesive: high strength, high temperature stability and chemical resistance.

Acrylic adhesive: Excellent bonding properties and chemical resistance.

3. Fuel cell manufacturing

In the fuel cell manufacturing process, adhesives are used to secure and seal the individual components. For example, a polymer electrolyte patch adhesive is required for fixation in electrolyte film assembly. Commonly used adhesives include:

Polyurethane adhesive: high strength, high temperature stability and chemical resistance.

Epoxy resin adhesive: Excellent bonding strength and chemical resistance.

Fluororubber: Excellent chemical resistance and high temperature resistance.

4. Automotive electronic equipment manufacturing

In the manufacturing process of on-board electronic devices, adhesives are needed to connect and fix components to ensure their stability and safety. For example, in the manufacturing process of products such as dashboards and navigation screens, adhesives are needed to connect and fix components. Commonly used adhesives include:

Acrylic adhesive: Excellent bonding properties and chemical resistance.

Thermoplastic elastomer (TPE) : Excellent flexibility and heat resistance.

Polyurethane adhesive: high strength, high temperature stability and chemical resistance.

In short, the application of adhesives in different new energy fields is diverse, and it is necessary to choose according to actual needs. In the future, with the continuous development of new materials and new technologies, adhesives will also become more efficient and high-quality, providing better support for the manufacturing of products in the field of new energy.
