abstract = {MXenes have emerged as one of the most interesting material
classes, owing to their outstanding physical and chemical
properties enabling the application in vastly different
fields such as electrochemical energy storage (EES). MXenes
are commonly synthesized by the use of their parent phase,
i.e., MAX phases, where “M” corresponds to a transition
metal, “A” to a group IV element, and “X” to carbon
and/or nitrogen. As MXenes display characteristic
pseudocapacitive behaviors in EES technologies, their use as
a high-power material can be useful for many battery-like
applications. Here, a comprehensive study on the synthesis
and characterization of morphologically different
titanium-based MXenes, i.e., Ti3C2 and Ti2C, and their use
for lithium-ion batteries is presented. First, the
successful synthesis of large batches (≈1 kg) of the MAX
phases Ti3AlC2 and Ti2AlC is shown, and the underlying
materials are characterized mainly by focusing on their
structural properties and phase purity. Second, multi- and
few-layered MXenes are successfully synthesized and
characterized, especially toward their ever-present surface
groups, influencing the electrochemical behavior to a large
extent. Especially multi- and few-layered Ti3C2 are
achieved, exhibiting almost no oxidation and similar content
of surface groups. These attributes enable the precise
comparison of the electrochemical behavior between
morphologically different MXenes. Since the preparation
method for few-layered MXenes is adapted to process both
active materials in a “classical” electrode paste
processing method, a better comparison between both
materials is possible by avoiding macroscopic differences.
Therefore, in a final step, the aforementioned
electrochemical performance is evaluated to decipher the
impact of the morphology difference of the titanium-based
MXenes. Most importantly, the delamination leads to an
increased non-diffusion-limited contribution to the overall
pseudocapacity by enhancing the electrolyte access to the
redox-active sites.},
