Manufacturing Process
The manufacturing process of 0.2mm thickness high porosity titanium fiber sintered felt battery materials involves several steps:
1. Fiber preparation. The first step is to prepare the titanium fibers, which are obtained through a specialized drawing process. The fibers are then treated with a surface agent to enhance their wettability and improve the bonding between the fibers.
2. Felt formation. The prepared titanium fibers are randomly oriented and compacted to form a non-woven felt structure. This process ensures a high degree of porosity and a large surface area.
3. Sintering. The felt is then subjected to a high-temperature sintering process, during which the fibers are partially melted and bonded together. This process results in a dense, interconnected network structure that exhibits excellent mechanical and electrical properties.
4. Post-processing. After sintering, the material undergoes additional processing, such as cutting and shaping, to meet the specific requirements of the intended application.
