Advancements in Operando NMR Analysis of Lithium-Ion Batteries

Electrochemical processes in a Li|LiPF6|LFP cell have been explored applying novel solid-state NMR technologies. Industry, Academia, and Technology partners are joining efforts to demonstrate the high potential of this approach for use in the energy storage industry.
Join Dragonfly Energy, Darmstadt Technical University, ePROBE and BRUKER BioSpin as they discuss about an experimental procedure for routine application of in-situ Solid-State NMR for battery research and manufacturing.

Lithium-ion batteries (LIBs) have been commercialized for 30 years and have made significant progress in high-power density, cycling life, and charging conditions. LIBs are used in portable digital devices, electric vehicles, and stationary energy storage. McKinsey predicts a huge rise of the global LIB demand over the next decade. Despite their outstanding properties, LIB technologies still face challenges in safety concerns, lifespan, energy density, costs, and environmental sustainability.

Elucidation of structural changes in an electrochemical system containing lithium as anode material, while charging/discharging processes take places, is essential for understanding of battery failure and for improving its design. Monitoring and identification of structure fractions formed in lithium/lithium-ion electrochemical cells is still a challenging task. An electrochemical cell consisting of electrodes, electrolytes etc. represents a complex multicomponent system, so that for its structural characterization under working condition special analytical techniques are required. In-situ solid-state NMR spectroscopy (ssNMR) has been proven as a powerful tool suitable to address structural changes in local environment of electrochemical cell components during operation.
