Summary: This article presents the use of rhamnolipids (RL) as efficient natural biosurfactants for the fabrication of nanocomposite MnO2-carbon nanotube electrodes for supercapacitors. The RL act as co-dispersants for MnO2 and carbon nanotubes, enabling efficient mixing and resulting in advanced capacitive properties. The approach offers advantages such as simplicity and the use of a biocompatible RL biosurfactant.

Summary: In this study, a CoMnFeO4/Polyaniline (S2) nanocomposite was prepared as high-performance supercapacitor electrode material using in-situ polymerization method. The S2 nanocomposite exhibited a high specific capacitance of 1610 F/g at a current density of 1 A/g and a capacitance retention of about 100% at a current density of 20 A/g after 600 cycles, indicating its relatively high efficiency. The excellent electrochemical performance of the S2 nanocomposite is attributed to the synergy between the good properties of PANI and the pseudo-capacitance properties of CoMnFeO4 nanoparticles.
