1. Two-dimensional ScTe₂ monolayer: An efficient anode material for sodium-ion battery and cathode material for lithium-ion and potassium-ion battery

Improved electrode materials result in high power, quick charge/discharge, and efficient conduction of electricity in metal-ion batteries. In this regard, our density functional theory (DFT)-based investigation reveals that the ScTe₂ monolayer exhibits essential features to function as an electrode material for metal-ion batteries (MIBs). The calculated minimum diffusion energy barriers for Li, Na and K are 0.32, 0.18, and 0.19 eV, respectively, which support an excellent charge/discharge rate for electrode materials. This system possesses a storage capacity of 357.27, 535.91, and 178.64 mAh/g with open-circuit voltage (OCV) amounting to 1.04, 0.88, and 1.96 V for Li, Na and K, respectively. These findings provide valuable insights for designing high-performance electrodes, advancing next-generation metal-ion batteries having improved efficiency and energy density.

Since the last two decades, significant research works have been done on lithium-ion batteries. However, due to the dearth of lithium and relative abundance of sodium and potassium, the research and development on sodium- and potassium-ion batteries have gained incredible attention. Here we study and report the electronic, thermal, and mechanical properties of two-dimensional Ti₂CFX (X = F, Cl, Br, and OH) monolayers and the adsorption-diffusion behavior of sodium and potassium atoms on these monolayers through density functional theory (DFT)-based calculations. Remarkably low diffusion barriers (in the range of 0.16–0.18 eV for Na and 0.07–0.10 eV for K) on the Ti₂CF₂, Ti₂CFCl, Ti₂CFBr, and Ti₂CFOH monolayers signify outstanding charge/discharge rate. Furthermore, the Ti₂CFX (X = F, Cl, Br, and OH) MXenes exhibit theoretical storage capacities of 367.92 (367.92), 330.60 (330.60), 518.96 (259.48), and 559.58 (373.06) mAh/g for Na (K) with open circuit voltages of 0.39 (0.81), 0.31 (0.74), 0.30 (0.68), and 0.26 (0.55) V, respectively. Therefore, the Ti₂CFX (X = F, Cl, Br, and OH) MXenes possess enormous potential for sodium-ion and potassium-ion batteries as anode material.
