摘要

为解决Ti

MXene电极材料因层间自堆叠导致离子传输受阻、超级电容性能衰减的关键问题，本研究以高比例少层Ti

MXene水溶液（1~3层占比96%）为前驱体，选取不同种类的有机溶剂如乙醇（ET）、乙腈（AN）、二甲基亚砜（DMSO），协同旋蒸工艺对材料进行结构与形貌调控，系统探究有机溶剂种类对材料层间距、微观形貌及电化学行为的影响规律。通过X射线衍射、扫描电子显微镜、傅里叶变换红外光谱对材料结构与形貌进行表征，结合循环伏安、恒流充放电、电化学阻抗谱及弛豫时间分布分析，评估褶皱状Ti

MXene在对称超级电容器与柔性微型超级电容器中的储能性能。X射线衍射结果表明，有机溶剂处理可显著增大MXene层间距并呈现DMSO

AN的规律；扫描电子显微镜显示改性后材料均形成褶皱状形貌，有效抑制层间堆叠。电化学测试表明，乙醇改性样品在低电流密度下输出最高比容量，适合高容量储能应用；乙腈改性样品电荷转移电阻与离子扩散电阻最小，高倍率充放电性能最优。在微型超级电容器中，乙醇改性电极的面积比电容与容量保持率显著优于未改性样品。本研究通过无外源插层剂的有机溶剂改性策略，实现Ti

MXene结构精准调控，为高性能MXene基储能器件的设计与制备提供实验依据与新的思路。

Abstract

To address the critical issue o

f hindered ion transport and degraded supercapacitor performance caused by interlayer self-stacking of Ti

MXene electrode materials

this study employed an aqueous solution of high-proportion few-layer Ti

MXene (96% consisting of 1-3 layers) as the precursor. Different organic solvents

ethanol (ET)

acetonitrile (AN)

and dimethyl sulfoxide (DMSO)

were combined with a rotary evaporation process to regulate the structure and morphology of the material. The influences of the organic solvent type on the interlayer spacing

micromorphology

and electrochemical behavior of the material were systematically investigated. The structure and morphology of the material were characterized using X-ray diffraction

scanning electron microscopy

and Fourier transform infrared spectroscopy. The energy storage performance of the corrugated Ti

MXene in symmetric supercapacitors and flexible micro-supercapacitors was evaluated using cyclic voltammetry

galvanostatic charge-discharge

electrochemical impedance spectroscopy

and relaxation time distribution analysis. X-ray diffraction results demonstrate that organic solvent treatment significantly enlarges the interlayer spacing of MXene

with the extent of expansion following the order DMSO

AN. Scanning electron microscopy images reveal that all modified materials exhibit a corrugated morphology

which effectively suppresses interlayer stacking. Electrochemical tests indicate that the ET-modified sample delivers the highest specific capacitance at low current densities

making it suitable for high-capacity energy storage applications. The AN-modified sample exhibits the lowest charge transfer resistance and ion diffusion resistance

resulting in optimal high-rate charge-discharge performance. In micro-supercapacitors

the ET-modified electrode presents significantly higher areal specific capacitance and better capacity retention rate than the unmodified sample. This study achieves precise structur

al regulation of Ti

MXene via an organic solvent modification strategy without the use of exogenous intercalators

providing experimental evidence and a viable route for the design and fabrication of high-performance MXene-based energy storage devices.
