Strict Operating Requirements
To ensure the integrity of experimental data and avoid contamination of sensitive battery components, the PP/PE/PP Disk must be unpacked and used under the following controlled conditions:
- Operate in an argon-filled glove box to prevent oxidation of electrode materials and electrolytes
- Maintain ambient humidity at less than 2% RH to eliminate moisture interference with electrochemical reactions
- Ensure a dust-free operating environment to prevent particle contamination during battery assembly
These requirements align with the standard protocols of research-level battery testing, supporting reliable and reproducible experimental results when using the PP/PE/PP Disk.
Core Functional Advantages
Precision Layered Isolation
The PP/PE/PP three-layer structure of this PP/PE/PP Disk enables precise separation between different battery components, preventing direct contact and short circuits while facilitating efficient ion exchange—essential for accurate electrochemical performance testing of new materials.
Excellent Chemical Compatibility
The composite material of this PP/PE/PP Disk is chemically inert to most battery electrolytes, avoiding adverse reactions that could skew test results. It is compatible with a wide range of electrode materials used in advanced battery R&D.
Stable Mechanical Performance
With balanced MD/TD tensile strength and durable layered construction, this PP/PE/PP Disk resists tearing and deformation during battery assembly, disassembly, and charge-discharge cycle testing, maintaining structural integrity throughout experiments.
Application Scenarios
This product is a dedicated accessory for CR20XX button battery R&D and testing, ideal for the following scientific research fields:
- Performance evaluation of new cathode/anode materials for button batteries
- Electrolyte compatibility and ion conductivity research
- Post-cycle disassembly and component analysis of experimental batteries
- Optimization of battery material layering structure and electrochemical performance
- Academic and industrial laboratory projects focused on next-generation battery technology
Quality Compliance
All raw materials and production processes adhere to international testing standards:
- Polypropylene (PP) and polyethylene (PE) raw materials comply with ISO 1872 specifications for chemical purity and inertness
- Tensile strength is tested in accordance with ASTM D882 protocols, ensuring consistent mechanical performance across batches
- Strict quality control is implemented for thickness uniformity and porosity consistency, meeting the high-precision requirements of scientific research experiments
