Heteroatom preintercalated Cl-terminated Ti₃C₂T_x MXene wrapped with mesoporous Fe₂O₃ nanospheres for improved sodium ion storage

Abstract

Developing multicomponent hybrid materials is an effective method to achieve structural stable anode materials for high-performance sodium-ion batteries (SIBs). In this work, mesoporous Fe2O3 nanospheres wrapped by heteroatoms pre-intercalated Cl-terminated...

Recent Advances and Perspectives of Lewis Acidic Etching Route: An Emerging Preparation Strategy for MXenes

“…SIBs possess a similar working mechanism to LIBs. It is well known that the working voltage of SIBs is lower than that of LIBs, thus resulting in a relatively low energy density of SIBs [179,180]. However, due to the abundance of sodium resources and attractive cost-effectiveness [181], SIBs are promising to be utilized in some fields that do not require high energy density, such as large-scale energy storage [182,183].…”

S- and Cl-functionalized Nb2C MXenes as novel anode materials for sodium-ion batteries: a first-principles study

“…[23][24][25][26][27][28] Recent theoretical investigations and experiments suggest that the energy storage capacities of MXenes strongly depend on the surface terminal functional groups. [29][30][31][32] Therefore, it is of great significance to study the storage capacities associated with surface terminal functional groups to further understand the energy storage mechanisms of MXenes.…”
