Infrared image analysis of energy storage batteries

Can energy storage electrodes be characterized with IR near-field measurements?

The first work to study an energy storage electrode with IR near-field measurements focused on illuminating phase distributions within lithium iron phosphate (LFP) microcrystals . In the work the LFP microcrystals were characterized at various states of lithiation, with PHI-based nanospectroscopy .

Can near-field IR multimodal characterization be applied to energy storage systems?

These near-field IR multimodal characterization schemes will no doubt be applied to more energy storage systems and chemistries in the future, and their capabilities expanded further still, so even more critically important physicochemical properties hidden at energy storage surfaces and interfaces will come to light.

What is IR nanospectroscopy?

First in situ IR nanospectroscopy of energy storage solid/solid interfaces and SEIs. First in situ and operando IR nanospectroscopy of solid-liquid electrolyte interfaces. Discovered a general methodology to create IR nanospectrsocy platforms for characterization of electrochemically controlled interfaces.

Who supported the battery materials research project?

This work was supported by the Assistant Secretary for Energy Efficiency and Renewable Energy, Office of Vehicle Technologies of the USDepartment of Energy under Contract No. DE-AC02-05CH11231, under the Battery Materials Research program, directed by Tien Duong (RK), and the Silicon Consortium Program, directed by B. Cunningham (RK and AD).

What is a sub-diffraction-limit low-energy infrared optical probe?

To this end, sub-diffraction-limit low-energy infrared optical probes that exploit near-field interactions within atomic force microscopy platforms, such as pseudoheterodyne nanoimaging, photothermal nanoimaging and nanospectroscopy, and nanoscale Fourier transform infrared spectroscopy, are all powerful emerging techniques.

Are IR spectroscopy probes non-destructive?

These relatively new and promising near-field probes for nanoscale vibrational imaging and spectroscopy are also generally non-destructive to the sample of interest as they typically operate in a tapping AFM mode, and the incident IR light has low photon energy.
