- Abstract
- In-operando laboratory x-ray computed tomography (XCT) enables non-destructive, real-time imaging of battery materials during electrochemical operation, providing critical insights into morphology evolution, degradation mechanisms, and performance limitations. This tutorial guides newcomers through the technique, emphasizing its role in battery research where dynamic processes like electrode plating, stripping, and phase transformations must be captured. Challenges such as optimizing temporal resolution versus image quality and reducing beam-induced damage are covered, with strategies like sparse sampling and super-resolution. Drawing on three examples—(1) hybrid 2D/3D imaging of zinc electrode evolution in various electrolytes Dzięcioł (2023); (2) high-frequency 3D in-operando study of anode morphology in a commercial zinc-air battery Dzięcioł (2025); and (3) a pressurized custom cell for air-sensitive lithium metal batteries Weckelmann (2025)—step-by-step instructions are provided. These instructions cover experiment design, execution, data handling, and practical tips. The tutorial stresses scripting for multi-modal synchronization, cell design for x-ray transparency, and artifact mitigation, equipping researchers to apply in-operando XCT effectively to various battery systems for innovative, sustainable solutions.
