Abstract
Herein we report on Li insertion into a new two-dimensional (2-D) layered Ti2C-based material (MXene) with an oxidized surface, formed by etching Al from Ti2AlC in HF at room temperature. Nitrogen sorption of treated powders showed desorption hysteresis consistent with the presence of slit-like pores. At 23m2 g−1, the specific surface area was an order of magnitude higher than untreated Ti2AlC. Cyclic voltammetry exhibited lithiation and delithiation peaks at 1.6V and 2V vs. Li+/Li, respectively. At C/25, the steady state capacity was 225mAh g−1; at 1C, it was 110mAh g−1 after 80 cycles; at 3C, it was 80mAh g−1 after 120 cycles; at 10C, it was 70mAh g−1 after 200 cycles. Since Ti2C is a member of the MXene family – where M is an early transition metal and X is C and/or N – that to date includes Ti3C2, Ta4C3, TiNbC, and (V0.5,Cr0.5)3C2, our results suggest that MXenes are promising as anode materials for Li-ion batteries.
► We report on reversible Li insertion into a new 2-D layered Ti2C-based material. ► Ti2C represents a new family of 2-D transition metal carbides and/or nitrides called “MXene”. ► Ti2C has oxidized surface and its behavior is comparable to titania based anodes. ► This new material can be used at fast charging and discharging rates (10C). ► This work opens a door for usage of MXene in lithium ion batteries.
