Scanning Probe Microscopy Facility for Operando Study of Redox Processes on Lithium ion Battery Electrodes

An Atomic Force Microscope (AFM) is combined with a special designed glovebox system and coupled to a Galvanostat/Potentiostat to allow measurements on electrochemical properties for battery research. An open cell design with electrical contacts makes it possible to reach the electrode surface with the cantilever so as to perform measurements...

Accessing lithium−oxygen battery discharge products in their native environments via transmission electron microscopy grid electrode

High-fidelity and facile ex situ transmission electron microscopy (TEM) characterization of lithium−oxygen (Li−O₂) batteries is still limited by challenges in preserving the native environment of Li−O₂ discharge products. The extreme reactivity and moisture sensitivity of the discharge products means that they are...

Operando Transmission Electron Microscopy Study of All-Solid-State Battery Interface: Redistribution of Lithium among Interconnected Particles

With operando transmission electron microscopy visualizing the solid-solid electrode-electrolyte interface of silicon active particles and lithium oxide solid electrolyte as a model system, we show that (de)lithiation (battery cycling) does not require all particles to be in direct contact with electrolytes across length scales of a few...
