Area of Science:

  • Materials Science
  • Electrochemistry
  • Energy Storage

Background:

  • Biochar carbon is a potential electrode material for electric double-layer capacitors.
  • Gamma radiation is explored as a method to modify biochar properties for enhanced electrochemical performance.

Purpose of the Study:

  • To investigate the effect of gamma radiation on biochar carbon properties.
  • To optimize biochar treatment for supercapacitor electrode applications.
  • To evaluate the electrochemical performance of gamma-irradiated biochar electrodes.

Main Methods:

  • Biochar carbon (YP-50) was exposed to gamma radiation at doses of 50, 100, and 150 kGy.
  • Electrochemical performance was evaluated using electric double-layer capacitors.
  • Characterization included analysis of pore structure, pore volume, particle size, and charge transfer resistance.

Main Results:

  • Gamma radiation significantly altered the pore structure and pore volume of biochar.
  • The biochar treated with 100 kGy gamma radiation exhibited a specific capacitance of 246.2 F g-1, a substantial increase from untreated biochar (115.3 F g-1).
  • This optimized dose also resulted in higher specific power (0.1 kW kg-1), specific energy (34.2 W h kg-1), excellent capacity retention (>96% after 10,000 cycles), and reduced charge transfer resistance (7.4 Ω).

Conclusions:

  • Gamma radiation is an effective pretreatment strategy for enhancing biochar carbon properties for supercapacitor electrodes.
  • The 100 kGy irradiation dose optimizes biochar morphology, porosity, and conductivity, leading to superior electrochemical performance.
  • This approach holds promise for developing high-performance supercapacitors for large-scale applications.
