Abstract

The presented work compared the etching behavior between combustion synthesized Ti₃AlC₂ (SHS-Ti₃AlC₂) and pressureless synthesized Ti₃AlC₂ (PLS-Ti₃AlC₂). Because the former had a more compact structure, it was harder to be etched than PLS-Ti₃AlC₂ under the same conditions. When served as anode material for Li-ion batteries, SHS-Ti₃C₂ showed much lower capacity than PLS-Ti₃C₂ at 1 C (52.7 and 87.4 mAh g⁻¹, respectively) due to the smaller d-spacing. Furthermore, Potentiostatic Intermittent Titration Technique (PITT) was used to determine the Li-ion chemical diffusion coefficient (D_Li⁺) of Ti₃C₂ in the range of 10⁻¹⁰ − 10⁻⁹ cm² s⁻¹, indicating that Ti₃C₂ could exhibit an excellent diffusion mobility for Li-ion.
