Researchers improve zinc flow battery performance by using nanotube-encapsulated organic redox molecule catholytes
Researchers at CSIR-Central Salt and Marine Chemicals Research Institute thermally encapsulated organic redox molecules within multiwalled carbon nanotubes to form a stable and flowable slurry for use as high-capacity catholytes in aqueous zinc flow batteries. The assembled batteries using these catholytes exhibited excellent cycling stability at an applied current density of 1.0 mA cm⁻², with a Coulombic efficiency of 99%.
