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.
