Comparative analysis of polydiphenylamine/MWCNT-COOH composites for supercapacitors: recovered vs. commercial nanotube electrodes

Key Points

• The study aims to explore the separation and reuse of active materials from lithium-ion battery cathodes for supercapacitor applications.
• Isolate components from polydiphenylamine/MWCNT-COOH composite cathodes.
• Test the performance of recovered materials in supercapacitor applications.
• Compare the efficiency of recovered materials to commercial nanotube electrodes.
• Recovered polydiphenylamine and MWCNT-COOH composites showed promising performance as active materials.
• Performance metrics of reused materials were comparable to those of commercial nanotube electrodes.
