Application Example

Evaluating the mechanical stiffness of battery nanostructures

Researchers at the University of Houston and the Singapore University of Technology and Design have created a silkworm cocoon-like silicon battery electrode using a non-invasive sacrificial template method, and studied their fracture mechanism using Hummingbird in-situ TEM Nano-Manipulator holder. The researchers were able to assemble a prototype nano-electrochemical cell with composites of nitrogen-doped carbon (NC) and porous silicon nano rods (NRs) affixed on the half TEM Cu grid and Li/Li2O lithium source/electrolyte attached to the movable probe. The probes were brought in contact, and the Cu probe with active materials was negatively biased (-2V) to perform lithiation of the nanostructure. During lithiation, the yolk-shell design of NC/Si NRs allowed silicon to expand freely in the internal void space and demonstrated excellent mechanical integrity of the material during cycling.
