This document outlines critical handling and compatibility constraints for the perforated coin cell case set. Adherence to these guidelines ensures reliable gas diffusion and sealing performance in battery research applications.

  • Pore Uniformity: The precision-machined mesh positive cap must be protected from physical deformation and particulate contamination to maintain the specified 0.2–0.5 μm pore distribution for uniform gas flow.
  • Material Compatibility: Electrolyte corrosion resistance of the 316L stainless steel substrate should be verified against the specific electrolyte chemistry used in the experiment to prevent pitting or sealing degradation.
  • Sealing Integrity: The IP67-rated sealing requires proper compression and alignment of the case components during crimping to ensure a watertight and gas-tight seal under operating conditions.

How does the 0.2–0.5 μm pore size in the perforated positive cap balance gas diffusion rate with electrolyte leakage risk for lithium-air battery testing?

The precision-machined mesh provides uniform pore distribution in the 0.2–0.5 μm range, which enables controlled gas permeation while maintaining an IP67 waterproof rating to prevent electrolyte leakage. This design, executed on 316L stainless steel substrates, ensures structural integrity under typical coin cell crimping pressures while delivering reproducible gas diffusion conditions for Li-air and Li-O₂ experiments.

Are these perforated coin cell cases compatible with organic carbonate electrolytes and high-voltage cathodes up to 5.0 V?

Yes, the cases are electrochemically validated for no side reactions within a -0.5 V to 5.0 V range via constant potential polarization and cyclic voltammetry tests, making them suitable for organic carbonate electrolytes common in lithium-air and gas-involved battery systems. The 316L stainless steel construction also offers corrosion resistance against mildly acidic or alkaline electrolyte environments typical in flow battery research.

Do the perforated coin cell cases require pre-cleaning or surface treatment before assembly inside an argon-filled glovebox?

No pre-cleaning is required because each set undergoes 100% dimensional inspection, sealing performance testing, and appearance inspection to ensure oil-free, burr-free, and impurity-free surfaces before shipment, and is packaged for direct glovebox use. The included 15.8 × 0.5 mm spacers and 15.4 × 1.1 mm springs are also precision-controlled within ±0.02 mm tolerances, allowing immediate assembly without additional processing.

Engineered for gas permeation and flow battery research, these perforated coin cell cases feature precision-machined 316L stainless steel mesh positive caps with 0.2–0.5 μm pores and tight ±0.02 mm tolerances, ensuring reproducible controlled gas diffusion. However, the default CR2032 size and fixed pore range may require customization for non-standard experimental setups.

Positive

  • Uniform pore distribution for reproducible gas diffusion: Precision-machined mesh positive caps provide consistent pore geometry and distribution, enabling controlled gas permeation and supporting accurate, reproducible experimental data across runs.
  • Electrochemically inert over wide voltage range: All materials have been verified via constant potential polarization and cyclic voltammetry to exhibit no side reactions within -0.5 V to 5.0 V, ensuring no interference with battery performance measurements.

Trade-offs

  • Default size limited to CR2032 format: The product is supplied only in CR2032 form factor; other cell sizes or custom dimensions require a separate customization request, potentially increasing lead time and minimum order quantities.
  • Fixed pore size range restricts gas diffusion flexibility: The positive cap pore size is fixed at 0.2–0.5 μm, which may not suit all gas diffusion or electrolyte permeation requirements; alternative porosities are only available through custom orders.

Every advanced material, component, equipment, and instrument in our catalog is backed by rigorous testing. We maintain strict internal quality management frameworks and align with CE conformity metrics to deliver transparent, reproducible performance data via our public open-science repository.
