Lithium-Ion Batteries - Boosting in Operando NMR Analysis

Electrochemical processes in a Li|LiPF6|LFP cell are being explored with new solid-state NMR technologies. Technology partners, Industry, and Academia are all coming together to demonstrate the great potential of this approach in the energy storage industry.

This webinar by Dragonfly Energy, Darmstadt Technical University, ePROBE and BRUKER BioSpin discusses an experimental procedure for the standard application of in-situ Solid-State NMR for battery manufacturing and research. 

Webinar Overview 

Over the last thirty years, Lithium-ion batteries (LIBs) have entered the commercial realm and made notable advancements in high-power density, cycling life, and charging conditions. LIBs can be seen powering electric vehicles, portable digital devices, and in stationary energy storage.

McKinsey has predicted a large-scale rise in global LIB demand throughout the next decade. Even with their impressive properties, LIB technologies have some remaining challenges in terms of lifespan, costs, safety concerns, energy density, and environmental sustainability.

Key Learning Objectives

Expand your knowledge of innovative ssNMR technologies for routine analysis in the energy storage industry.

  • Learn about in-situ ssNMR and its marked potential to become the industry standard for routine monitoring of electrochemical processes under operating conditions.
  • Gain insight into the electrochemical processes of a Li|LiPF6|LFP cell and how they have been explored in terms of applying novel solid-state NMR technologies.
  • Understand how in-situ ssNMR enables the analysis of ionic transport and monitors microstructural changes in Li|LiPF6|LFP.
  • Explore degradation of the electrolyte and dendrite formation at different states of charge.

What to Expect

This webinar elucidates the structural changes within an electrochemical system featuring lithium as the anode material during charging and discharging processes. Understanding these changes is vital for pinpointing battery failures and facilitating subsequent design enhancements.

Monitoring and identifying structure fractions formed in lithium/lithium-ion electrochemical cells is still challenging. Thus, electrochemical cells that consist of electrodes, electrolytes, etc., represent a complex multicomponent system.

Special analytical techniques are required to complete a structural characterization under working conditions. A powerful tool for this task is in-situ solid-state NMR spectroscopy (ssNMR), which has proven to be suitable for addressing the structural changes in the local environment of electrochemical cell components during operation.
