Annealing induced a well-ordered single crystal δ-MnO2 and its electrochemical performance in zinc-ion battery

Abstract Herein, the formation and electrochemical performance of a novel binder-free turbostratic stacked/ well-ordered stacked δ-MnO2-carbon fiber composite cathodes in deep eutectic solvent (DES) based zinc-ion battery (ZIB) is reported. Results of morphological, elemental, and structural analyse...
