Cation Intercalation and High Volumetric Capacitance of Two-Dimensional Titanium Carbide

Abstract

Toward Titanium Carbide Batteries Many batteries and capacitors make use of lithium intercalation as a means of storing and transporting charge. Lithium is commonly used because it offers the best energy density, but also because there are difficulties in storing larger cations without disrupting the crystal structure of the host. Lukatskaya et al. (p. 1500 ) developed a series of MX compounds, where M represents a transition metal and X is carbon or nitrogen.The compound Ti 3 C 2 forms a two dimensional layered structure, which is capable of accommodating a wide range of cations, including multivalent ones, either spontaneously or electrochemically
