Journal ArticleDOI
Cation Intercalation and High Volumetric Capacitance of Two-Dimensional Titanium Carbide
Maria R. Lukatskaya,Olha Mashtalir,Chang E. Ren,Yohan Dall'Agnese,Patrick Rozier,Pierre-Louis Taberna,Michael Naguib,Patrice Simon,Patrice Simon,Michel W. Barsoum,Yury Gogotsi +10 more
TL;DR: This study demonstrates the spontaneous intercalation of cations from aqueous salt solutions between two-dimensional (2D) Ti3C2 MXene layers, and provides a basis for exploring a large family of 2D carbides and carbonitrides in electrochemical energy storage applications using single- and multivalent ions.
Journal ArticleDOI
Intercalation and delamination of layered carbides and carbonitrides
Olha Mashtalir,Michael Naguib,Vadym Mochalin,Yohan Dall'Agnese,Min Heon,Michel W. Barsoum,Yury Gogotsi +6 more
TL;DR: Intercalation of hydrazine, and its co-intercalation with N,N-dimethylformamide, resulted in increases of the c-lattice parameters of surface functionalized f-Ti3C2, from 19.5 to 25.48 and 26.8 Å, respectively.
Journal ArticleDOI
Prediction and Characterization of MXene Nanosheet Anodes for Non-Lithium-Ion Batteries
Yu Xie,Yohan Dall'Agnese,Yohan Dall'Agnese,Michael Naguib,Yury Gogotsi,Michel W. Barsoum,Houlong L. Zhuang,Paul R. C. Kent +7 more
TL;DR: In this paper, a class of two-dimensional transition-metal carbides, called MXene nanosheets, are predicted to serve as highperforming anodes for non-lithium-ion batteries by combined first-principles simulations and experimental measurements.
Journal ArticleDOI
High capacitance of surface-modified 2D titanium carbide in acidic electrolyte
Yohan Dall'Agnese,Yohan Dall'Agnese,Yohan Dall'Agnese,Maria R. Lukatskaya,Kevin M. Cook,Pierre-Louis Taberna,Pierre-Louis Taberna,Yury Gogotsi,Patrice Simon,Patrice Simon +9 more
TL;DR: In this paper, the electrochemical behavior of Ti3C2, a two-dimensional titanium carbide from the MXene family, in H2SO4 electrolyte is reported.
Journal ArticleDOI
Two-Dimensional Vanadium Carbide (MXene) as Positive Electrode for Sodium-Ion Capacitors
Yohan Dall'Agnese,Yohan Dall'Agnese,Yohan Dall'Agnese,Pierre-Louis Taberna,Pierre-Louis Taberna,Yury Gogotsi,Patrice Simon,Patrice Simon +7 more
TL;DR: This work investigated the electrochemical behavior of 2D vanadium carbide, V2C, from the MXene family, and investigated the mechanism of Na intercalation by XRD and achieved capacitance of ∼100 F/g at 0.2 mV/s.
