The application of slitting machine in the processing of new energy materials

With the rapid development of the new energy industry, the demand for new energy materials such as lithium battery separators and photovoltaic films is growing. As an important equipment for slitting these materials into specific widths and lengths, slitting machines play a vital role in the processing of new energy materials.

1. Lithium battery separator slitting:

• Application scenario: Lithium battery separator is one of the key components of lithium battery, and it is necessary to cut the wide separator substrate into a narrow separator that meets the size requirements of the battery.

• Technical Requirements:

◦ High-precision slitting: The slitting accuracy of the separator directly affects the performance and safety of the battery, and the slitting machine needs to have high-precision tension control, deviation correction system and cutting system.

◦ Clean environment: Diaphragm production has extremely high requirements for environmental cleanliness, and the slitting machine needs to have dustproof, anti-static and other functions, and can be operated in a clean room.

◦ On-line detection: real-time detection of key indicators such as thickness and porosity of the separator to ensure product quality.

• Development Trends:

◦ Ultra-thin separator slitting: With the increase of battery energy density requirements, the thickness of the separator is continuously reduced, which puts forward higher requirements for the accuracy and stability of the slitting machine.

◦ High-speed slitting: Increase the slitting speed to meet the needs of mass production.

◦ Intelligent slitting: realize the automation and intelligent control of the slitting process to improve production efficiency and product quality.

2. Photovoltaic thin film slitting:

• Application scenario: Photovoltaic thin-film solar cells need to cut a wide film into a narrow film that meets the size requirements of the cell.

• Technical Requirements:

◦ High-precision slitting: The slitting accuracy of photovoltaic thin films directly affects the conversion efficiency of the cell, and the slitting machine needs to have high-precision tension control, deviation correction system and cutting system.

◦ Non-destructive slitting: Photovoltaic thin films are very fragile and require a special cutting process by the slitting machine to avoid damage to the film.

◦ On-line detection: real-time detection of key indicators such as film thickness and light transmittance to ensure product quality.

• Development Trends:

◦ Flexible film slitting: With the development of flexible photovoltaic technology, new requirements are put forward for the slitting technology of flexible film.

◦ Efficient slitting: Improve slitting efficiency to meet the needs of mass production.

◦ Green slitting: Adopt an environmentally friendly cutting process to reduce the impact on the environment.
