The Construction of Highly Conductive Framework in Mn<sub>3</sub>O<sub>4</sub>@C‐MWCNTs Slurry for Aqueous Zinc‐Based Semi‐Solid Flow Batteries
Aqueous zinc-based semi-solid flow batteries (AZSSFBs) are promising large-scale energy storage devices due to their low cost and superior safety. The formation of a conductive network in the slurry plays an important role in the capacity of active materials and the stability of suspension. Meanwhile, the suspension stability of the slurry will determine the cycle life of AZSSFBs. Herein, metal-organic-framework-derived carbon-coated Mn<sub>3</sub>O<sub>4</sub>@C composites are fabricated and dispersed in the aqueous electrolyte to construct a stable 3D conductive carbon framework in slurry by combining multi-walled carbon nanotubes (MWCNTs). The 3D conductive carbon framework can not only facilitate rapid electron transportation, but also enhance the suspension stability of slurry, ensuring stable electron conduction for Mn<sub>3</sub>O<sub>4</sub> in the fluidic semi-solid slurry. Based on Mn<sub>3</sub>O<sub>4</sub>@C-MWCNTs semi-solid slurry, AZSSFBs display enhanced electrochemical performance.
