Herein, the double-transition-metal (DTM) MXene Mo2Ti2C3 (M), derived from its MAX phase Mo2Ti2AlC3 via selective chemical etching, was combined with polyaniline (PANI) through in situ polymerization to obtain composites with varying M\/PANI ratios to enhance electrochemical performance. The structural, chemical, and morphological properties of the synthesized materials were systematically investigated using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS), confirming the successful formation of MXene and its effective integration with PANI fibers. The electrochemical behavior of all the prepared electrode materials was investigated using cyclic voltammetry (CV), galvanostatic charge\u2013discharge (GCD), and electrochemical impedance spectroscopy (EIS) in an organic electrolyte. As a result, the optimized composite exhibits a high specific capacitance of 704 F g\u20131 at a current density of 2 A g\u20131. Furthermore, an asymmetric supercapacitor device assembled using the optimized composite as the positive electrode delivers a specific capacitance of 384.9 F g\u20131 at 1 A g\u20131, along with an energy density of 104.8 Wh kg\u20131, and a power density of 1400 W kg\u20131. These results highlight the significant potential of DTM M\/PANI nanocomposites as advanced electrode materials for efficient energy storage applications.<\/jats:p>","DOI":"10.1021\/acsomega.6c06468","type":"journal-article","created":{"date-parts":[[2026,9,10]],"date-time":"2026-09-10T09:01:32Z","timestamp":1789030892000},"page":"56145-56158","source":"Crossref","is-referenced-by-count":0,"title":["Double-Transition-Metal\nMo2Ti2C3 Mxene-Polyaniline Composites\nfor High-Performance Supercapacitors"],"prefix":"10.1021","volume":"11","author":[{"given":"Nisha H.","family":"Makani","sequence":"first","affiliation":[{"name":"Fayetteville State University , , , ,","place":["Fayetteville, North Carolina, United States, 28301"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shrabani","family":"De","sequence":"additional","affiliation":[{"name":"North Carolina A&T State University , , , ,","place":["Greensboro, North Carolina, United States, 27411"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mia","family":"Thompson","sequence":"additional","affiliation":[{"name":"Fayetteville State University , , , ,","place":["Fayetteville, North Carolina, United States, 28301"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-0163-8545","authenticated-orcid":true,"given":"Peshal","family":"Karki","sequence":"additional","affiliation":[{"name":"Fayetteville State University , , , ,","place":["Fayetteville, North Carolina, United States, 28301"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4651-7393","authenticated-orcid":true,"given":"Bishnu Prasad","family":"Bastakoti","sequence":"additional","affiliation":[{"name":"North Carolina A&T State University , , , ,","place":["Greensboro, North Carolina, United States, 27411"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5083-6250","authenticated-orcid":true,"given":"Bhoj Raj","family":"Gautam","sequence":"additional","affiliation":[{"name":"Fayetteville State University , , , ,","place":["Fayetteville, North Carolina, United States, 28301"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,10]]},"reference":[{"key":"2026092211035387700_cit1","volume-title":"Electricity 2025","author":"International Energy Agency (IEA).","year":"2025"},{"key":"2026092211035387700_cit2","doi-asserted-by":"publisher","first-page":"176924","DOI":"10.1016\/j.jallcom.2024.176924","article-title":"Supercapacitors\nfor Energy Storage\nApplications: Materials, Devices and Future Directions: A Comprehensive\nReview","volume":"1009","author":"Shuja","year":"2024","journal-title":"J.
