abstract = {MXenes, as an emerging class of 2D materials, display
distinctive physical and chemical properties, which are
highly suitable for high-power battery applications, such as
lithium ion batteries (LIBs). Ti3C2Tx (Tx = O, OH, F, Cl) is
one of the most investigated MXenes to this day; however,
most scientific research studies only focus on the design of
multilayered or monolayer MXenes. Here, we present a
comprehensive study on the synthesis of few-layered Ti3C2Tx
materials and their use in LIB cells, in particular for
high-rate applications. The synthesized Ti3C2Tx MXenes are
characterized via complementary XRD, Raman spectroscopy,
XPS, EDX, SEM, TGA, and nitrogen adsorption techniques to
clarify the structural and chemical changes, especially
regarding the surface groups and intercalated cations/water
molecules. The structural changes are correlated with
respect to the acidic and basic post-treatment of Ti3C2Tx.
Furthermore, the detected alterations are put into an
electrochemical perspective via galvanostatic and
potentiostatic investigations to study the pseudocapacitive
behavior of few-layered Ti3C2Tx, exhibiting a stable
capacity of 155 mAh g–1 for 1000 cycles at 5 A g–1. The
acidic treatment of Ti3C2Tx synthesized via the in situ
formation of HF through LiF/HCl is able to increase the
initial capacity in comparison to the pristine or basic
treatment. To gain further insights into the structural
changes occurring during (de)lithiation, in situ XRD is
applied for LIB cells in a voltage range from 0.01 to 3 V to
give fundamental mechanistic insights into the structural
changes occurring during the first cycles. Thereby, the
increased initial capacity observed for acidic-treated
MXenes can be explained by the reduced co-intercalation of
solvent molecules.},
