Strict Operating Requirements
To ensure experimental accuracy and avoid contamination of battery materials, the Polypropylene Disc must be unpacked and used under the following controlled conditions:
- Operate in an argon-filled glove box to prevent oxidation of sensitive battery components
- Maintain ambient humidity at less than 2% RH to avoid moisture interference with electrochemical reactions
- Ensure the operating environment is dust-free to prevent particle contamination during battery assembly
These requirements align with the standards of research-level battery testing, ensuring the integrity of experimental data when using the Polypropylene Disc.
Core Functional Advantages
Precise Material Isolation
The uniform porosity and thickness of this Polypropylene Disc enable stable separation between battery electrodes and electrolytes, preventing direct contact and short circuits while facilitating ion exchange—critical for accurate electrochemical performance testing.
Excellent Thermal & Mechanical Stability
Low thermal shrinkage at 120℃ ensures the structural integrity of the Polypropylene Disc during high-temperature battery charge-discharge cycles. High puncture strength and directional tensile performance resist mechanical damage to the Polypropylene Disc during battery assembly and disassembly operations.
Research-grade Compatibility
The PP material of the Polypropylene Disc is chemically inert to most battery electrolytes, avoiding adverse reactions that could interfere with experimental results. Its consistent batch-to-batch performance supports reproducible research outcomes.
Application Scenarios
This product is tailored for advanced battery R&D and testing, ideal for the following fields:
- New electrode material performance evaluation for CR20XX button batteries
- Electrolyte compatibility and ion conductivity research
- Post-cycle disassembly and analysis of experimental button batteries
- Academic and industrial laboratory projects focused on battery material innovation
Quality Compliance
All raw materials and production processes comply with international testing standards:
- Polypropylene raw material meets ISO 10993 chemical inertness specifications
- Tensile strength and puncture resistance are tested in accordance with ASTM D882 and ASTM D726 protocols
- Batch consistency is verified through strict quality control, ensuring each lot meets research-grade performance criteria
