The main goal of this project is to gain fundamental insight, identify and unravel the atomistic factors governing structure evolution in 2D transition metal carbides (TMCs/MXenes) during lithiation and de-lithiation using novel real-time characterization at the nanoscale.

To achieve this goal, in this project 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.

Project concept

This project will be realized through scientific collaboration between research groups from Poland ŁUKASIEWICZ Research Network – PORT Polish Center for Technology Development, Wroclaw, and Norway University of Oslo and SINTEF. The partners will conduct together in situ experiments to simulate real life battery conditions inside aberration-corrected Scanning/Transmission electron microscopes to investigate structural changes in the physical matter and -probe analytically their chemical nature. Such atomic level understanding of the processes will enable to inform for better design and development these materials to fully harness their Li-ion loading capacities.

The successful realization of this project will lead to the future proof of concept based on the new design of 2D structure devices for energy storage.
