Key Features & Advantages

Homogeneous Material Purity: Formulated with chemically inert polyethylene matrices to isolate impurity interference, ensuring complete compliance with non-aqueous liquid electrolyte environments.
Enhanced Operational Efficiency: Specifically engineered to demonstrate superior tensile thresholds and robust puncture deflection, preventing internal short circuits and structural tearing under repeated mechanical cell compression.
Optimized Microstructure: Pre-cut sizing and flat film contours match automated laboratory equipment, significantly reducing processing errors and enhancing data reproducibility across evaluation batches.

APPLICATION SCOPE: Core isolating matrix substrates for high-precision button cell experimentation, electrolyte compatibility screening, ion transmission verification, and post-cycle disassembly failure mode tracking.

PACKAGING: Dispatched inside air-tight defensive packaging systems, organized with separate batch slots to maintain high surface cleanliness during long-distance transit.

IMPORTANT NOTICE: This pre-cut functional matrix must be handled strictly inside controlled argon-filled spaces. Keep containers tightly integrated and manage exclusively under moisture-free dustless parameters to block unexpected oxidation or side reactions on active electrode components before definitive testing validation.

Constraints

This polyethylene film is engineered for use in CR20XX button battery assembly and requires handling within an inert atmosphere. The material's performance depends on strict control of humidity and particulate contamination during deployment.

Atmosphere Requirement: The film must be handled inside an argon-filled glove box to prevent oxidation of battery components.
Humidity Limit: The ambient relative humidity must be maintained below 2% RH to avoid moisture interference with electrochemical reactions.
Dust-Free Environment: The operating environment must be free of dust and particulates to prevent contamination during battery assembly.
Battery Compatibility: This pre-cut film is specifically designed for CR20XX series button batteries and may not fit other cell formats.

HowTo

Proper deployment of this film requires a controlled environment to maintain its integrity and battery performance. Follow these steps to ensure contamination-free assembly.

Required Equipment: Argon-filled glove box

Transfer to Glove Box
Transfer the unopened package containing the pre-cut polyethylene film into an argon-filled glove box.
Check Humidity
Confirm the ambient relative humidity inside the glove box is below 2% RH before opening the package.
Inspect Workspace
Inspect the workspace for dust and remove any particulates before opening the film package.

FAQ

How does the 44±5% porosity of Atomfair's pre-cut PE film influence the trade-off between electrolyte wetting rate and mechanical puncture resistance in CR20XX button cell assembly?

The 44±5% porosity provides a balanced porous structure that facilitates electrolyte wetting and ion transport while maintaining a puncture strength of ≥600G and tensile strengths of MD ≥1600kgf/cm² and TD ≥1400kgf/cm². This combination ensures both efficient ion exchange and structural integrity during assembly and cycling.

Is Atomfair's pre-cut polyethylene film compatible with CR20XX button batteries using lithium metal anodes or carbonate-based electrolytes?

Yes, the chemically inert polyethylene material does not react with most battery electrolytes, including common carbonate-based systems, and its stable structure supports testing with lithium metal anodes. The product requires use in an argon-filled glove box with humidity below 2% RH to prevent electrode and electrolyte degradation.

What controlled environment conditions are required when unpacking Atomfair's PE film for CR20XX button battery assembly?

The film must be unpacked and handled exclusively in an argon-filled glove box with ambient humidity maintained below 2% RH in a dust-free environment. These conditions prevent oxidation of electrode materials, moisture interference with electrochemical reactions, and particle contamination, in alignment with standard research-level battery testing protocols.

Assessment

This pre-cut PE separator delivers consistent 20±2 µm thickness and 44±5% porosity for reliable ion transport and >600 g puncture strength for mechanical durability in CR20XX coin cells, but mandatory use in an argon glove box with <2% RH and CR20XX-specific geometry constrain deployment flexibility.

Positive

Precision material isolation: Uniform porosity (44±5%) and thickness (20±2 µm) prevent electrode contact and short circuits while enabling stable ion exchange for accurate electrochemical testing.
Superior mechanical strength: Puncture strength ≥600 G and balanced MD/TD tensile strength (≥1600/1400 kgf/cm²) resist mechanical damage during assembly, cycling, and disassembly, preserving structural integrity.

Trade-offs

Controlled environment mandatory: Unpacking and use require an argon-filled glove box, <2% RH humidity, and a dust-free environment to prevent oxidation, moisture interference, and particle contamination.
CR20XX-specific pre-cut format: The film is precision-cut exclusively for CR20XX series button batteries, limiting its application to that specific coin cell geometry and form factor.
