Strict Operating Requirements
To guarantee experimental accuracy and prevent contamination of sensitive battery components, the Polyethylene Film must be unpacked and used under the following controlled conditions:
- Operate in an argon-filled glove box to avoid 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, ensuring the integrity and reproducibility of experimental data when using the Polyethylene Film.
Core Functional Advantages
Precision Material Isolation
The uniform porosity and thickness of this Polyethylene Film enable stable separation between battery electrodes and electrolytes, preventing direct contact and short circuits while facilitating efficient ion exchange—an essential feature for accurate electrochemical performance testing.
Superior Mechanical Strength
With high puncture resistance (≥600G) and balanced MD/TD tensile strength, this Polyethylene Film resists mechanical damage during battery assembly, disassembly, and charge-discharge cycle testing, maintaining structural integrity throughout experiments.
Research-grade Compatibility
The chemically inert PE material of this Polyethylene Film does not react with most battery electrolytes, avoiding adverse chemical interactions that could skew test results. Its consistent batch-to-batch performance supports reliable, repeatable research outcomes.
Application Scenarios
This product is tailored for advanced battery material innovation, ideal for the following research fields:
- Performance evaluation of new electrode materials for CR20XX button batteries
- Electrolyte compatibility and ion conductivity research
- Post-cycle disassembly and component analysis of experimental button batteries
- Academic and industrial laboratory projects focused on next-generation battery technology
Quality Compliance
All raw materials and production processes adhere to international testing standards:
- Polyethylene raw material complies with ISO 1872-1 specifications for chemical inertness and purity
- Tensile strength and puncture resistance are tested in accordance with ASTM D882 and ASTM D726 protocols
- Strict batch quality control ensures each lot meets research-grade performance criteria, supporting consistent experimental results
