X-ray inspection of energy storage batteries

Can X-ray computed tomography be used to study commercial batteries?

Adopting X-ray computed tomography (XCT) for ex-situ characterization of battery materials has gained interest in the past decade. The main goal of this paper is to demonstrate the effectiveness of several X-ray computer tomography techniques to study commercial batteries.

How is X-ray tomography revolutionizing battery research and development?

Nature Reviews Materials 3, 293–295 (2018) Cite this article X-ray tomography is revolutionizing battery research and development by enabling non-destructive, 3D imaging of the inside of battery cells before, during and after operation.

What X-ray techniques are used in battery research?

In this review, several state-of-the-art in situ/operando synchrotron-based X-ray techniques and their combination with other characterization tools for battery research are introduced. Various in situ cell configurations and practical operating tips for cell design and experimental set-ups are also discussed.

Why is X-ray CT used in battery characterization?

CT can also be used to distinguish and segment species based on the varying X-ray absorption, which thus allows for select materials to be studied dynamically. A comparison of the X-ray CT with common battery characterization techniques is given in Table 1.

What is quality control and X-ray inspection techniques in battery cell production?

Quality Control and X-ray Inspection Techniques in Battery Cell Production The aim of this Section is to provide a systematic overview of the most important inner features of intermediate products in specific production steps and the status of inspection techniques in lab- and large-scale LIB production.

Can X-ray imaging study battery degradation?

Most of the in situ/operando X-ray imaging experiments have been focused on the first or first several charge-discharge cycles only. However, studies of the degradation mechanisms of battery materials inevitably require tracking the electrochemical reaction of the batteries for long-term cycling.
