M.Tang, R.Fu, M.Deschamps, K.Romanenko, A.Jerschow, 'The Methodology of Electrochemical In situ NMR and MRI', NMR and MRI of Electrochemical Energy Storage Materials and Devices 2 71-105 (2021) doi:10.1039/9781839160097-00071
Non-destructive Nuclear Magnetic Resonance (NMR) plays a crucial role to
unveil mechanisms of batteries under operation conditions. In situ NMR
characterization offers intermediate information, which is very important for
the performance of working devices, such as diffusion, kinetics, and dynamics
that cannot be obtained by conversional ex situ approaches. This chapter
introduces general considerations for performing in situ NMR experiments
and summarizes designs of battery cells used for in situ NMR characterization.
In addition, Magnetic Resonance Imaging (MRI) is a powerful method
for visualization of materials with the aid of a magnetic field gradient to
encode positions of nuclear spins. In situ MRI studies have contributed to
an understanding of the fundamental phenomena that are associated with a
battery's performance and failure mechanisms. Here we provide an overview
of “electrochemical MRI” developments over the past two decades.
