Coin Cell Battery Cases 316 Stainless Steel for High Voltage Electrochemical Testing

Product Overview

These premium coin cell cases provide an ultra-reliable, chemically resilient encapsulation solution specifically developed for advanced battery chemistry research, electrochemical energy storage prototyping, and half-cell or full-cell characterization. Fabricated from high-grade 316 stainless steel, this hardware package delivers outstanding resistance to pitting, crevice corrosion, and oxidative degradation when exposed to aggressive non-aqueous electrolytes, high-voltage cathode materials, and ionic liquids. By offering superior chemical inertness compared to standard austenitic alloys, these cases ensure that measured electrochemical responses reflect the true intrinsic properties of your active materials rather than parasitic side reactions.

Designed to support standard cell fabrication protocols, the case components integrate seamlessly into university laboratories, national research institutes, and industrial battery R&D lines. Whether testing novel solid-state electrolytes, sodium-ion chemistries, silicon-anode composites, or high-potential lithium nickel manganese cobalt oxides, these coin cell assemblies guarantee precise alignment and uniform internal stack pressure. The consistent mechanical geometry minimizes contact resistance, maintains uniform current density distribution across the electrode surface, and prevents localized polarization effects during extended galvanostatic cycling.

Every batch undergoes rigorous quality assurance protocols to ensure microscopic burr-free edges, flawless structural uniformity, and strict dimensional tolerances. When paired with standard crimping dies and automated or manual hydraulic crimping machines, these cases achieve a hermetic seal that completely eliminates electrolyte leakage and atmospheric contamination. Researchers can confidently execute long-term cycle life studies, high-rate charge-discharge profiling, and elevated-temperature calendar aging without risking premature cell dry-out or degradation caused by ambient moisture and oxygen ingress.

Key Features

• Premium 316 Stainless Steel Metallurgy: Formulated with molybdenum-bearing austenitic steel to deliver significantly enhanced resistance to halide corrosion, aggressive organic carbonates, and high-voltage electrolyte decomposition compared to standard 304 grades.
• Optimized High-Voltage Stability: Demonstrates an extended electrochemical stability window that suppresses anodic dissolution and current collector oxidation at operational potentials exceeding 4.2V vs. Li/Li⁺.
• Precision Micro-Machined Tolerances: Manufactured with exacting dimensional control to ensure consistent internal headspace, reproducible crimping stroke depth, and uniform compression against internal spacers and wave springs.
• Flawless Burr-Free Edge Finishing: Subjected to specialized mechanical and chemical deburring processes that prevent micro-punctures in internal polymeric sealing gaskets and ensure zero short-circuit pathways during mechanical compression.
• Hermetic Sealing Compatibility: Engineered to mate flawlessly with standard sealing rings and automated coin cell crimpers, establishing an airtight, moisture-proof barrier that preserves electrolyte integrity over thousands of continuous cycles.
• Universal Testing System Adaptability: Fully compatible with standard laboratory coin cell holders, multi-channel battery testing systems, multichannel potentiostats, and automated impedance spectroscopy fixtures.
• Pre-Cleaned Cleanroom Packaging: Packaged in sealed 100-set enclosures designed to minimize surface grease, organic residues, and particulate contamination, drastically streamlining preparation workflows inside inert-atmosphere gloveboxes.
• Versatile Form Factor Options: Available across standard laboratory thicknesses to accommodate diverse electrode stack configurations, thick pelletized solid electrolytes, or standard thin-film slurry coatings.
