Overview

Randomized trial shows improved capacitance in manganese-based frameworks, suggesting enhancements for energy storage applications.

Key Points

  • This research aims to enhance the performance of manganese-based metal-organic frameworks (Mn-MOFs) for supercapacitors through ligand ratio engineering.
  • Mn-MOFs were synthesized using varying molar ratios of BTC and BDC as organic linkers.
  • Physicochemical and electrochemical characterizations were performed to evaluate their performance.
  • Electrochemical measurements were conducted in a 6 M KOH aqueous electrolyte.
  • MOF-1 achieved a specific capacitance of 1015 F/g at 0.5 A/g, surpassing MOF-2 (818 F/g) and MOF-3 (420 F/g).
  • After 1000 cycles, MOF-1 retained 111% of its initial capacitance, indicating excellent stability.
  • MOF-1 exhibited low series resistance (7.46 Ω) and low charge transfer resistance (3.97 Ω), ensuring efficient ion transport.
