Preparation of microwave-assisted expired honey derived electrodes with excellent performance for supercapacitors

Key Points

• The aim is to develop highly efficient electrodes from expired honey for use in supercapacitors.
• Employed microwave and hydrothermal methods to prepare biochar from expired honey.
• Activated biochar using KOH and carbonized it, followed by Co 2+ catalysis.
• The developed electrodes exhibited excellent performance for supercapacitors.
• Enhanced electrochemical properties were observed due to the unique preparation methods.
