X-Ray Diffraction

InSight Series

● Designed for in-situ transmission XRD testing of pouch cells.
● Simultaneously acquiring cathode/anode XRD data.
● Temperature control range: -30°C to 300°C.

Introduction

Soft-pack (pouch) batteries play a critical role in both cutting-edge research and next-generation commercial energy storage. Yet studying their internal behavior during charge and discharge— especially over long cycles—has been limited by the constraints of traditional in-situ XRD methods. The InSight Series changes that.

This dedicated in-situ Transmission X-ray Diffractometer is purpose-built for soft-pack battery analysis. Unlike conventional reflective-style molds, the InSight Series uses a vertical transmission geometry to collect diffraction data from both the anode and cathode simultaneously—across the full cell thickness.

Paired with a high-intensity 1600 W Mo X-ray source, a photon-counting 2D array detector, and precision temperature control from -30°C to 300°C, the InSight Series offers unmatched resolution, speed, and stability for real-time battery material studies.

Why In-situ Transmission XRD for Soft-Pack Batteries?

True Long-Term Cycling:
Unlike coin cell molds, soft-pack batteries offer superior sealing and stability for thousands of cycles.
Full-Depth Material Insight:
Vertical transmission geometry collects diffraction data through the entire pouch— enabling dual-electrode analysis.
Superior Resolution at Any Thickness:
Focused beam transmission ensures peak clarity, even in thicker pouch cells.
Thermal Behavior Included:
Variable-temperature stage enables in-situ measurements at both sub-zero and high- temperature conditions.
Electrochemistry + Structure, Together:
Seamless integration with an electrochemical workstation allows simultaneous control and data acquisition during charging/discharging.
