Abstract

Lithium-ion capacitors (LICs) have gained attention as advanced energy storage systems, combining the superior energy density of lithium-ion batteries with the exceptional power density and extended cycle life characteristic of supercapacitors. MXenes, a class of two-dimensional transition metal carbides and nitrides, have attracted considerable interest as potential anode materials for LICs due to their unique properties such as high electrical conductivity, large surface area, and tunable surface chemistry. This mini review examines recent rational strategies for enhancing the performance of MXene-based anodes in lithium-ion capacitors (LICs), with a particular focus on structural engineering and surface functionalization. We provide an in-depth analysis of how specific structural and surface changes directly influence interlayer spacing, surface chemistry, and thereby electrochemical properties of MXenes and subsequently their performance as electrode material for LIC with an attempt to investigate the correlation between structural modifications in MXene and electrochemical performance in LIC devices.

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
