Enhanced Li‐Ion Accessibility in MXene Titanium Carbide by Steric Chloride Termination
Abstract
Pseudocapacitance is a key charge storage mechanism to advanced electrochemical energy storage devices distinguished by the simultaneous achievement of high capacitance and a high charge/discharge rate by using surface redox chemistries. MXene, a family of layered compounds, is a pseudocapacitor‐like electrode material which exhibits charge storage through exceptionally fast ion accessibility to redox sites. Here, the authors demonstrate steric chloride termination in MXene Ti 2 C T x (T x: surface termination groups) to open the interlayer space between the individual 2D Ti 2 C T x units. The open interlayer space significantly enhances Li‐ion accessibility, leading to high gravimetric and volumetric capacitances (300 F g−1 and 130 F cm−3) with less diffusion limitation. A Li‐ion hybrid capacitor consisting of the Ti 2 C T x negative electrode and the LiNi 1/3 Co 1/3 Mn 1/3 O 2 positive electrode displays an unprecedented specific energy density of 160 W h kg−1 at 220 W kg−1 based on the total weight of positive and negative active materials.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
