Hierarchically Porous and Hetero‐Structured Black Phosphorus/Ti₃C₂T_X MXene Aerogel Fiber for Wearable Supercapacitors with Implantable Capability

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(51)

Published: Aug. 22, 2024

Abstract Architected fibrous electrodes with hierarchically porous, stable interface coupling, and good biocompatibility that accelerates charge transfer storage are vital to realize high‐performance fiber‐shaped supercapacitors (FSCs) toward wearable implantable systems. Here, a porous hetero‐structured black phosphorus/Ti 3 C 2 T X MXene aerogel (A‐BP/Ti ) fiber based on electrostatic self‐assembly microfluidic spinning methods is reported. The as‐prepared A‐BP/Ti interconnected networks, high conductive skeleton, substantial interfacial building exhibits low diffusion energy barrier of H + , the large adsorption fast electron conduction, excellent structural stability by density functional theory calculations in situ/ex situ characteristics. As result, presents boosted electrolyte ion kinetic capacitance 369 F g −1 . Furthermore, asymmetric FSCs deliver 6.39 Wh kg long cycling 20 000 cycles, thereby successfully powering devices. More importantly, combining hydrogel adhesion agent, can firmly adhere tissues show significant bending (88.52% retention after 5000 cycles), impressively adhesive capability tissue fluid or wetted surface, considerably no cell toxic. work offers broad path for designing technology applications.

Published: March 3, 2025

Abstract MXene film‐derived flexible supercapacitors have shown great application foreground for wearable electronics, but the capacitive characteristics, especially when faced with mechanical deformations, are not satisfactory. Herein, a new kind of electrode, MX/D‐MoO 3 , is developed by using Ti C 2 T x film (MX) and defect‐rich MoO (D‐MoO ) as “main body” “spacer‐contributor”, respectively. Results indicate that, D‐MoO intercalation, notably enlarged layer spacing nanosheets boosted electrochemical active sites fulfilled, which facilitated wondrous property increases 342% 239% compared to raw MX MX/MoO Particularly, ‐60 has high specific capacitance 2734.3 mF cm −2 at 1 mA surpasses most counterparts reported thus far. The ‐60‐based all‐solid‐state supercapacitor presents largest energy density 96.3 µWh 205.9 µW an outstanding power 1871.4 18.6 . Meanwhile, impressive stability retention 91.8% after 5 000 cycles flexibility 90.3% under bending angles from 0 180° also exhibited. superior properties facile preparation endow promising applications in storage.
