abstract

  • Rechargeable battery systems, including Li-ion and Na-ion batteries, form the basis of modern portable technologies and are key to the electrification of 21st century energy utilization. Over the past ~30 years, magnetic resonance methods have provided critical insight into electrode material structure, electronic structure, and electrolyte dynamics. This chapter aims to cover this research effort by highlighting key findings by research groups around the world. We begin with a general introduction on rechargeable batteries, particularly focusing on Li-ion batteries. This is followed by a review of NMR studies of cathode material structure and dynamics, including a discussion of relevant NMR methods for probing ion dynamics. A variety of cathode chemistries as well as both liquid-state and solid-state electrolytes are considered. Finally, the emergence of real-time, operando methods to probe electrochemical lithium insertion and plating mechanisms at the anode is shown to be a powerful contribution of the field of magnetic resonance (both NMR and MRI) to the advancements of rechargeable battery technology.
