Batteries are highly complex systems. They are composed of various solid and liquid components (including anode, cathode, electrolyte), which continuously undergo chemical reactions during the charging and discharging processes.

Solid-state Nuclear Magnetic Resonance (NMR) spectroscopy is well-suited to unravel the underlying battery chemistries. It offers high chemical specificity, is non-destructive and allows for the examination of amorphous phases and dynamic processes. One particularly powerful tool is operando NMR, which involves the simultaneous NMR analysis of battery materials during the charge and discharge cycles. ePROBE offers specialized solid-state operando NMR probes and equipment for various battery cell geometries.

Coin cells and pouch cells can be found in commercial electronic devices and are both very popular cell geometries in battery research.
ePROBE offers NMR probes and sample holders specifically designed for the operando analysis of whole coin/ pouch cells. Besides standard stainless-stell coin cells, we offer coin cells made of Ti for better RF penetration.
