Overview

This study demonstrates improved electrochemical performance in hybrid-MOF electrodes, indicating significant advancements in supercapacitor technology.

Key Points

  • The optimized ZIF-67:Ni (1:2) electrode achieved a specific capacity of 161.2 mA h g-1 at 1 A g-1, indicating superior performance over ZIF-67.
  • Capacity retention after 5000 cycles reached 74.6%, demonstrating excellent cycling stability for ZIF-67:Ni composite electrodes.
  • The asymmetric supercapacitor device using ZIF-67:Ni (1:2) exhibited a specific energy of 36.97 W h kg-1 at 0.5 A g-1, highlighting its potential in energy storage applications.
  • Enhanced porous structures contributed to reduced charge transfer resistance, facilitating better ionic transport and electrochemical performance.
