Description

TITANIUM NITRIDE COATED COIN CELL CASES

RESEARCH GRADE MATERIAL

Product Overview
This premium series provides an advanced hardware framework, delivering a high-purity titanium nitride coated button battery case set engineered precisely for lithium ion electrochemical research stacks. Utilizing a robust 316 stainless steel core substrate, each coin cell cases set features a protective 0.5 μm layer designed to secure exceptional electrolyte corrosion resistance. This uniform surface modification substantially drops electrical contact resistance, balancing multi-phase stability margins during rigorous charge-discharge benchmarking while protecting vulnerable active components from delamination.

Key Features & Advantages
  • Premium Protective Crystalline Nitride Shielding: Features a 99.9% high-purity coating array designed to resist intensive electrolyte erosion across aggressive chemical frameworks.
  • Uniform Low Resistance Surface Boundary: Delivers high electronic transition properties and minimized contact resistance limits, extending dynamic stack cycling life.
  • Flawless standard Dimension Accuracy: Fabricated under rigid tolerances to directly fit standard processing molds without extra setup alterations.

APPLICATION SCOPE: Calibrated for precision testing and validation runs of lithium button cells, advanced sodium-ion architectures, sulfide/oxide solid-state systems, lithium-air reaction enclosures, and high-voltage prototyping configurations.
QUALITY CONTROL PACKAGING: Supplied in standard packs of 10 sets. Each component completes 100% boundary inspection, coating matrix thickness validation, and seal verification to confirm an impurity-free, oil-free surface ideal for immediate glovebox entry.
IMPORTANT NOTICE: Unless specified otherwise, default companion internals such as elastic springs or spacers use standard 304 grade steel. To prevent moisture tracking or oxidation, unsealed assemblies must enter protected atmosphere environments or vacuum glovebox lock chambers straight away. Manage components under the guidance of certified lab supervisors.

The TiN coating (0.5 μm) on 316 stainless steel is designed for electrolyte corrosion resistance and low contact resistance. Handle cases with care to avoid scratching the coating, and store in a dry environment to prevent contamination.

  • Coating Integrity: Avoid mechanical abrasion of the TiN layer during handling to maintain corrosion resistance and electrical performance.

How does the 0.5 μm TiN coating thickness balance corrosion resistance and contact resistance in CR2032 coin cell cases?

The 0.5 μm TiN coating thickness is optimized to deliver both superior electrolyte corrosion resistance and low contact resistance, as demonstrated by the 99.9% purity titanium nitride layer. This thickness prevents delamination and oxidation under long-term use while maintaining the electrical performance needed for enhanced battery cycle life and charge-discharge efficiency.

Are these TiN-coated coin cell cases compatible with standard 2032-type crimping tools and assembly processes?

Yes, the cases have standard 20 mm diameter × 3.2 mm height dimensions, perfectly matching 2032-type coin cell specifications. They are directly compatible with conventional coin cell assembly processes and do not require any additional adjustments to existing crimping tools or workflows.

Do the ATOMFAIR TiN-coated coin cell cases require any pre-cleaning or preparation before use in a glovebox?

No pre-cleaning is necessary; each case set undergoes 100% dimensional inspection, coating thickness verification, and sealing performance testing, and is shipped oil-free, burr-free, and impurity-free. They can be used directly for battery assembly inside gloveboxes without additional preparation steps.

ATOMFAIR CR2032 TiN-coated coin cell cases deliver a 99.9% pure titanium nitride coating on a 316 stainless steel substrate, providing low contact resistance and enhanced corrosion resistance for lithium battery R&D. The standard CR2032 form factor ensures straightforward integration, but the included 304 stainless steel accessories do not share the TiN coating, and the product is limited to this specific size unless custom ordered.

Positive

  • High-purity TiN coating performance: The 99.9% purity TiN coating (~0.5 μm) on 316 stainless steel provides superior electrolyte corrosion resistance and low contact resistance, demonstrably enhancing battery cycle life and charge-discharge efficiency.
  • Standard compatibility and quality control: Precisely matches CR2032 dimensions and is compatible with conventional coin cell assembly processes, with research-grade batch consistency ensured by strict coating uniformity and dimensional tolerance controls.

Trade-offs

  • Limited to CR2032 form factor: This product is designed specifically for 20 mm × 3.2 mm coin cells; other sizes or materials require custom ordering via inquiry, introducing lead-time and minimum-order considerations.
  • Uncoated 304 SS accessories included: Default accompanying accessories (spacers, springs, etc.) are made of 304 stainless steel, which does not receive the TiN coating and may exhibit different corrosion resistance in aggressive electrolyte environments.

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.
