How it Works

Correlate the structure and chemistry of a sample (HRTEM, electron diffraction, EELS, etc.) with its electrical properties.

Manipulate the mobile biasing probe with high spatial resolution to make electrical contacts.

Control—uncoupled—coarse and fine movements along the X, Y, and Z axes. Coarse movements are actuated with thumb-screws. Fine movements are actuated with a piezoelectric controlled with the included controller and graphical user interface.

Take low noise electrical data with individual coax cables.

Use standard 3 mm half grid samples or FIB lift-out grids to prepare your samples

In-situ TEM of microstructural evolution in composite solid-state Li-ion batteries during charge/discharge cycles

Researchers at the University of Central Florida (UCF) have studied the structural integrity of a novel composite electrode composed of a polymer-derived ceramic nanoparticle and edge-functionalized graphene oxide during electrochemical lithiation and delithiation cycles.

They assembled a prototype nanobattery cell with a lithium metal and a SiCNO composite electrode and performed in-situ TEM lithation and delithation for at least two cycles using Hummingbird Scientific’s Biasing Manipulator TEM holder. The observed results demonstrated extraordinary structural stability of the SiCNO nanoparticles with only a 9.36% linear expansion during the lithiation (See Movie on the Left).
