Evaluation of MXene Ti3C2 Charge-Discharge Behaviors as an Electrode Material for Intercalation Batteries

Eliminating A element from the MAX phases, the resulted 2D structure, named MXene, can be used as the electrode material for the intercalation, namely, Li-ion, Na-ion, K-ion, and Mg-ion batteries. MXene Ti3C2, produced by etching Ti3AlC2, is a promising intercalation electrode material, which is systematically evaluated in this article by taking data from literature. The diagrams provide a manner to assess and compare the most important characterizations, i.e., rate-capability and performance. The evaluations show that the synthesis methods of the pristine MAX phase as well as the final MXene play vital roles on the properties. The rank of synthesis methods and also commercial pristine material is recognized and reported based on the analyzed properties. Moreover, effectiveness of the additives, dopants, compositing, nanosizing, and etching is assessed precisely. Also, comparison between different types of intercalation batteries regarding the usage of MXene as the electrode is performed. This article paves the way for future studies and evaluations of this kind of electrode materials. It guides the researchers to modify, design, and engineer their manufactured electrodes to meet higher quality of the properties.
