Li-ion storage properties of two-dimensional titanium-carbide synthesized via fast one-pot method in air atmosphere

Guoliang Ma

Jin Xu

Structural bidimensional transition-metal carbides and/or nitrides (MXenes) have drawn the attention of the material science research community thanks to their unique physical-chemical properties. However, a facile and cost-effective synthesis of MXenes has not yet been reported. Here, using elemental precursors, we report a method for MXene synthesis via titanium aluminium carbide formation and subsequent in situ etching in one molten salt pot. The molten salts act as the reaction medium and prevent the oxidation of the reactants during the high-temperature synthesis process, thus enabling the synthesis of MXenes in an air environment without using inert gas protection. Cl-terminated Ti₃C₂T_x and Ti₂CT_x MXenes are prepared using this one-pot synthetic method, where the in situ etching step at 700 °C requires only approximately 10 mins. Furthermore, when used as an active material for nonaqueous Li-ion storage in a half-cell configuration, the obtained Ti₂CT_x MXene exhibits lithiation capacity values of approximately 280 mAh g⁻¹ and 160 mAh g⁻¹ at specific currents of 0.1 A g⁻¹ and 2 A g⁻¹, respectively.

The energy industry has taken notice of zinc-iodine (Zn-I₂) batteries for their high safety, low cost, and attractive energy density. However, the shuttling of I₃⁻ by-products at cathode electrode and dendrite issues at Zn metal anode result in short cycle lifespan. Here, a tripartite synergistic optimization strategy is proposed, involving a MXene cathode host, a n-butanol electrolyte additive, and the in-situ solid electrolyte interface (SEI) protection. The MXene possesses catalytic ability to enhance the reaction kinetics and reduce I₃⁻ by-products. Meanwhile, the partially dissolved n-butanol additive can work synergistically with MXene to inhibit the shuttling of I₃⁻. Besides, the n-butanol and I⁻ in the electrolyte can synergistically improve the solvation structure of Zn²⁺. Moreover, an organic-inorganic hybrid SEI is in situ generated on the surface of the Zn anode, which induces stable non-dendritic zinc deposition. As a result, the fabricated batteries exhibit a high capacity of 0.30 mAh cm⁻² and a superior energy density of 0.34 mWh cm⁻² at a high specific current of 5 A g⁻¹ across 30,000 cycles, with a minimal capacity decay of 0.0004% per cycle. This work offers a promising strategy for the subsequent research to comprehensively improve battery performance.

MXenes are two‐dimensional transition metal carbides and/or nitrides with unique physiochemical properties and have attracted extensive interest in numerous fields. However, current MXene synthesis methods are limited by hazardous synthesis conditions, high production costs, or difficulty in large‐scale production. Therefore, a general, safe, cost‐effective, and scalable synthesis method for MXenes is crucial. Here, we report the fast synthesis of MXenes in the open air using a molten salt‐shielded synthesis (MS³) method, which uses Lewis‐acid salts as etchants and a low‐melting‐point eutectic salt mixture as the reaction medium and shield to prevent MXene oxidation at high temperatures. Carbide and nitride MXenes, including Ti₃C₂T_x, Ti₂CT_x, Ti₃CNT_x, and Ti₄N₃T_x, were successfully synthesized using the MS³ method. We also present the flexibility of the MS³ method by scaling the etching process to large batches of 20 and 60 g of Ti₃AlC₂ MAX precursor in one pot. When used as negative electrodes, the prepared MS³‐MXenes delivered excellent electrochemical properties for high‐rate Li‐ion storage.
