Batteries - better understanding and improving batteries with X-Ray CT
Innovation in batteries means more room for inspection. X-ray CT contributes to this new generation of batteries for NEVs by ensuring efficiency and reliability. Conventional means of materials analysis often require the destruction of the sample and do not allow the evolution of a battery to be monitored over the charge and discharge cycles. In addition, these techniques provide two-dimensional information only, which is unsuitable for the analysis of a three-dimensional porous network. In order to improve the performance of batteries, X-ray Computed Tomography provides a technical solution to the challenge of understanding materials analysis and porous networks.
Batteries are the main and most expensive component of an electric car so to ensure flawless stack, X-ray inspection gives deep insights into every manufacturing step, from the creation and optimization of new batteries to the final assembly line.
This means the inspection of:
> Battery cells - measure and analyze cells, observe the conversion of energy with in-situ CT
> Battery electrodes - monitor and inspect during charge and discharge cycles, measure the geometry for better precision when added to the pack thanks to Nano CT
> Battery materials - analyze the assembly and detect defects before mass manufacturing
> Battery packs - inspect the complete enclosure of batteries by module or as a whole
