Operating Requirements
For optimal performance and to avoid contamination that may affect experimental data accuracy, the product must be unpacked and used under the following controlled conditions:
- Operate in an argon-filled glove box
- Maintain ambient humidity at less than 2% RH
- Ensure the operating environment is free of dust and electrochemical contaminants
This strict operation standard aligns with the environmental requirements of scientific research-level battery testing, ensuring the integrity of battery material isolation and reaction data when using the Polypropylene Disc.
Core Functional Advantages
Precise Material Isolation
The uniform porosity and thickness of the PP disc enable stable separation of battery electrodes and electrolytes, preventing direct contact and short circuits while allowing ion exchange, which is critical for accurate electrochemical performance testing.
Excellent Thermal & Mechanical Stability
Low thermal shrinkage rate at high temperatures (120℃) ensures the structural integrity of the Polypropylene Disc during battery charge-discharge cycles. High puncture strength and tensile performance resist mechanical damage during battery assembly and disassembly.
Research-grade Compatibility
The material is chemically inert to most battery electrolytes, avoiding chemical reactions that could interfere with experimental results, making this Polypropylene Disc ideal for new energy material R&D.
Application Scenarios
As a dedicated supporting component for CR20XX button batteries, this Polypropylene Disc is widely used in the following scientific research fields:
- New battery electrode material performance testing
- Electrolyte compatibility and ion conductivity research
- Button battery disassembly and post-cycle analysis
- Academic and industrial laboratory battery R&D projects
Quality Compliance
The polypropylene raw material complies with ISO 10993 biocompatibility and chemical inertness standards, ensuring no adverse reactions with battery components. All performance parameters are tested in accordance with ASTM D882 (tensile strength) and ASTM D726 (puncture resistance) international testing protocols, guaranteeing consistent quality of the Polypropylene Disc for scientific research applications.
