Title: MXenes as anode materials for Li-, Na- and K-ion rechargeable batteries
Affiliation: Uppsala University

Abstract

The work presents current results on using delaminated MXenes films (2D restacked sheets of transition metal carbides/nitrides having surface termination groups (T) such as –OH, –F or =O). Currently titanium carbide, Ti3C2Tx-compositions, are investigated as negative electrode materials for Li-, Na- and K-ion batteries. The fundamental questions to answer are: i) which electrochemical reactions occur in the electrode during cycling in a half-cell setup? ii) which species are formed during the SEI formation? and iii) how could the electrode design be altered in order to insure effective Li+(Na+, K+) intercalation into the structure?
Authors attempt to answer these questions by means of coupling cycling voltammetry and galvanostatic cycling with XPS, SEM as well as synchrotron-based techniques such as HAXPES and NEXAFS.
Findings will thus enable materials optimization for energy storage applications and provide suggestions on materials to be used for lithium-ion batteries and beyond.
