一般描述

Mxenes find extensive use in LiBs and rechargeable non-lithium-ion (Na+, K+, Mg2+, Ca2+, and Al3+) batteries. This MXene is a suitable candidate for Li-ion batteries because of its higher electrical conductivity and Li storage capacity comparable with graphite electrodes. This MXene has been explored as anode , cathode and separators in battery applications.

应用

Ti3C2Tx MXenes are a novel type of two-dimensional (2D) material composed of layered carbides of transition metals. MXenes have excellent thermal and electrical conductivity, heat resistance, and excellent volumetric capacitance, whilst having the highest electromagnetic (EMI) shielding effectiveness among similar synthetic 2D materials. Among its several applications, MXenes have been highlighted for:
  • Active material for energy storage devices (e.g. supercapacitors, lithium-based batteries);
  • Nanocomposites for power generation;
  • Biomedical applications;
  • Catalyst;
  • EMI Shielding.
