2D MXenes based anode materials for all-solid-state Li-ion batteries (2D-SSB)

Project partners

Together we aim to develop chemical vapor deposition (CVD) growth methods for the synthesis of Mo₂C, V₂C Cr₂C and Ti₂C 2D MXenes. Fundamental studies using in-situ (S)TEM and near in-situ XPS will be performed to gain deeper understanding of CVD growth mechanisms. Process methodologies based on FIB-SEM will be developed to precisely micro-manipulate 2D MXene layers. The electronic structure/states of as grown MXenes as a function of thickness and upon reducing and oxidizing conditions will be studied by in-situ and near situ by EELS and XPS. And then we intend to integrate and fabricate MXenes based full micro-sized all-solid-state batteries (ASSBs) by FIB-SEM on MEMS TEM chips for in-situ (S)TEM investigations to study atomic structural changes in MXenes and at their interface with the solid electrolyte.
