In-situ X-ray Diffraction on a LiCoO₂ Pouch Cell Battery

The steadily increasing popularity of e-mobility and renewable energy sources has created a great need for the development of efficient and safe energy storage materials and methods. X ray diffraction (XRD) is a common method for the characterization of battery materials as it allows non-destructive, in-situ or operando investigations of the material properties and structural changes in batteries during charging, discharging or storage.


According to a report published in 2021, the market share of electric vehicles has increased by 400 % between 2015 and 2019, making up a market share of 2.5 % in 2019. This trend is projected to continue, with a projected market share for electric vehicles of up to 30 % by 2030.1 One of the main challenges connected with this huge shift towards e-mobility is the development of new batteries. These batteries require high capacity, fast charging speed and a long lifetime to compete with traditional internal combustion engines. At the same time, they should be safe and reliable in all weather conditions, and even when involved in an accident.

The example of e-mobility highlights the necessity of developing new, high-performance materials. One of the main focuses of this development is the need to acquire a good understanding of the structure-property relationship of battery active-materials. X-ray diffraction (XRD) is a useful tool for this. The non-destructive method provides detailed insights at all steps of the battery lifecycle, from investigating the raw materials before assembly, to in-situ determination of the structural changes occurring during use.
