Abstract
One-step room temperature liquid-phase co-precipitation technology is applied in the field of energy storage, which has the advantages of mass production and simple operation. Using this technique, we have directly synthesized MnO2 and amorphous MnSe2. By compounding with carbon nanotubes, the prepared electrodes achieved high discharge capacity (451.1 mAh·g−1 at 0.1 A g−1) and remarkable cycling stability (87.24% after 2000 cycles). The Zn//MnSe2/CNTs battery shows excellent power density (3762 W kg−1) and energy density (301 Wh·Kg−1). This work is expected to achieve mass production of electrode materials, which provides great potential for the application of Selenium in zinc-ion batteries.
