In-situ TEM probing of lithium interfaces for solid-state batteries

Using Hummingbird Scientific’s in-situ TEM Biasing Manipulator holder, researchers at Toyota Research Institute of North America and the University of Pennsylvania devised an experiment in which air-sensitive lithium metal is brought in contact with novel solid-state electrolytes to observe the degradation mechanism during the lithium charge and discharge cycles. They observed dendrites and delamination of lithium metal upon reaction with lithium thiophosphate (LPS) electrolyte. However, when the same electrolyte is doped with lithium iodide, the dopant plays a protective role and prevents such degradation. This improves the lithium cycling capacity. The in-situ TEM manipulation and biasing capabilities can accelerate the fundamental understanding and microstructural evolution of nanostructured battery materials to develop better batteries.

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).
