Operando measurements allow non-invasive, time-resolved insight into battery charge cycles. Especially solid state batteries and high temperature stable ionic liquids are of interest, but require high operating temperatures up to 300°C. These temperatures are currently at the limit of hardware capabilities of superconducting NMR magnets, which are operated at -270°C. Although the magnets are thermally insulated from the probe, local overheating due to heated probes can lead to damage or destruction of the superconducting coils. Additionally, there are currently no probe interfaces available, where an elechtrochemical cell can be included and kept at a stable temperature. The present project should solve these problems and focuses at four key development directions:

• building of a high-temperature operando NMR probe, including a control unit
• thermal insulation of the probe space @ 300°C from the magnet bore @ 21°C
• connection and operation of high-temperature cells up to 300°C
• development and monitoring of high-temperature cells for novel battiers

In situ NMR measurements are a powerful analytical tool for the investigation and optimization of battery and energy storage materials. This method is being used by universities, research facilities and industry all over the world, but is currently limited by hardware. We therefor want to develop robot assisted in situ NMR probes for battery research, which will allow (a) an automatic recalibation of optimal measurement parameters, (b) the adjustment of temperature and flow and (c) high-resolution in situ MAS measurements. Technical difficulties will be overcome and battery research elevated to a new analytical level: efficient, user-friendly and widely applicable.
