CR2016 In Situ XRD X Ray Analysis Double Sided Window Coin Cell Battery Case

Product Overview

This specialized coin cell casing is an advanced hardware solution engineered specifically for in-situ and operando X-ray diffraction (XRD) characterization of electrochemical storage materials. Featuring dual-sided optical-grade polyimide (Kapton) transmission windows, the casing allows focused X-ray beams to penetrate directly through both the positive and negative sides of an operational battery cell. By maintaining active electrochemical performance during real-time structural analysis, this system eliminates the artifacts, degradation, and relaxation phenomena traditionally associated with ex-situ post-mortem battery teardowns.

Designed primarily for academic institutions, energy research laboratories, synchrotron facilities, and commercial battery R&D centers, this hardware accommodates advanced studies across lithium-ion, sodium-ion, solid-state, and next-generation battery chemistries. The specialized architecture allows researchers to map crystallographic phase transitions, lattice expansion and contraction, staging phenomena in intercalation compounds, and solid-state reaction kinetics under live charge-discharge conditions.

Manufactured under stringent dimensional and metallurgical tolerances, this cell assembly ensures high repeatability and hermetic integrity across long-duration cycling protocols. A dedicated aluminum coating on the interior of the positive shell provides superior electrochemical passivation, preventing high-voltage parasitic oxidation and electrolyte corrosion. This level of material stability guarantees clean, high-signal-to-noise diffraction patterns while safeguarding delicate laboratory equipment against electrolyte leakage.

Key Features

• Dual Polyimide (Kapton) Transmission Windows: Integrated with precision-aligned 10 mm diameter optical apertures on both the cathode and anode shells, providing an unhindered beam path for both transmission and reflection XRD geometries with minimal background scattering.
• Precision-Calibrated 0.18 mm Window Thickness: The polyimide membrane is engineered to a uniform 0.18 mm thickness, delivering an optimal balance between structural rigidity to withstand cell crimping pressures and superior X-ray photon transmittance across standard laboratory and synchrotron wavelengths.
• Protective Cathode Aluminum Coating: The internal surface of the positive shell features a high-purity aluminum coating with a thickness of less than 0.01 mm, safeguarding the casing against high-potential anodic dissolution and minimizing parasitic side reactions during high-voltage cycling.
• Standardized CR2016 Dimensional Compatibility: Built to the universally recognized 20 mm diameter and 1.6 mm height profile, the casing integrates smoothly with standard coin cell crimpers, testing fixtures, multi-channel potentiostats, and automated XRD sample stages.
• Exceptional Hermetic Sealing Reliability: Engineered to maintain structural and atmospheric seals when crimped with compatible sealing gaskets, isolating volatile organic electrolytes and air-sensitive electrode materials from ambient moisture and oxygen over extended testing cycles.
• Low Background Scattering Interference: The selected polyimide window material exhibits an exceptionally low and predictable amorphous diffraction background, enabling precise deconvolution of subtle crystalline phase peaks and low-intensity superlattice reflections.
• Standardized Five-Piece Research Packaging: Supplied in convenient 5-set packaging units, each batch undergoing strict quality inspection to ensure consistent shell dimensions, defect-free window adhesion, and uniform aluminum coating distribution.
