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

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.

Project partners

ŁUKASIEWICZ Research Network – PORT Polish Center for Technology Development:

  • Alicja Bachmatiuk PhD DSc, PI & Head of Materials Science and Engineering Center,
  • Sandeep Gorantla PhD, Research Scientist.

SINTEF:

  • Dr. Spyros Diplas, PI & Research Manager-Materials Physics group,
  • Dr. Martin F. Sunding, Research Scientist.

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.
