Nuclear Magnetic Resonance

Description

Solid-state NMR can provide very accurate information about the structure and the dynamics of molecules and ions in electrochemical materials. This is crucial for the understanding and the development of energy storage devices. Solid-state NMR is a sensitive technique to short-range order that surpasses traditional techniques of materials characterization as X-ray diffraction or electron microscopy in the study of amorphous materials and complements these techniques in the study of crystalline materials. Furthermore, solid state NMR can provide dynamic information with atomic specificity in highly disordered and even fully amorphous materials.

The technologies of the solid-state NMR platform at the CIC energiGUNE are specially designed for the characterization of the materials used for energy storage including in-situ measurements during device operation and variable temperature studies (-120 C degrees to +400 C degrees).

The solid state NMR platform at CIC energiGUNE was recognized in 2018 by Bruker-Spain as the reference center in solid-state NMR in the Spain.

Instrumentation

BRUKER AVANCE III 200 MHZ
The Avance III 200 MHz was installed at CIC in March 2012. It is a wide bore, low magnetic field magnet dedicated to the study of paramagnetic materials which are a frequent component in battery and supercapacitor electrodes.

Available Probes:
- Double resonance 1H/19F-X DVT CPMAS 1.3 mm probe that can reach ultra-fast spinning speeds of up to 67kHz.
- Double resonance 1H-X DVT CPMAS 4 mm probe, that can reach temperatures up to 400ºC and spinning speeds up to 18 kHz.
Variable temperature measurements between 400ºC and -100ºC.
BRUKER AVANCE III 500 MHZ
The Avance III 500 MHz was installed at CIC in April 2012. It is a wide bore magnet especially suited for non magnetic materials where high resolution is desired.
