AI Technical Summary
Technical Problem
State-of-the-art supercapacitors have short charge-discharge cycles and limited Coulombic efficiency, failing to achieve high energy density and long-lasting performance.
Method used
Incorporating uranium into carbon nanotube (CNT) or graphene oxide (GO) structures to enhance specific capacitance and energy density, with uranium doping increasing capacitive behavior and pseudo-capacitive effects, thereby extending cycle life and improving Coulombic efficiency.
Benefits of technology
The uranium-doped supercapacitors exhibit increased specific capacitance and energy density, achieving 15,000 charge-discharge cycles with 95% Coulombic efficiency and demonstrating superior electrochemical performance with pseudo-capacitive effects.
