Short summary
Short summary
We developed a workflow using finite element methods to optimise electrochemical cell designs for in operando nuclear magnetic resonance by accurately matching magnetic field and radio frequency field simulations with experimental data. Guidelines for enhanced sensitivity and field homogeneity are given. A radio frequency amplification effect in coin cells is described by empirical formulae, which have the potential to improve spatial selectivity in future in operando applications.

Short summary
We demonstrate the potential of designing magnetic resonance spectroscopy experiments for investigating electrochemically relevant setups. Up until now, such nuclear magnetic resonance measurements were heavily obstructed by the fact that conductive components interact with magnetic fields. In a new approach, we show that this interaction can be deliberately utilized to achieve a spatially selective measurement of electrochemical environments.
