In Situ TEM study of Lithium-Ion Solid-State Battery

Safety issues associated with the flammable organic liquid electrolytes in the Li-Ion Batteries (LIBs) force researchers to look for alternatives which contains safer solid state electrolytes instead.

In this work the authors reported the successful preparation of an all-solid-state LIB sample directly on the MEMS-based Nano-Chip. Atomic scale HAADF- and ABF-STEM imaging of the cathode during in situ electrochemical delithiation of the working battery cell has been achieved using DENSsolutions biasing system.
