Mno2 Nanowires

Recently, rechargeable zinc-ion batteries (ZIBs) have gained a considerable amount of attention due to their high safety, low toxicity, abundance, and low cost. Traditionally, a composite manganese oxide (MnO2) and a conductive carbon having a polymeric binder are used as a positive electrode. In general, a binder is employed to bond all materials together and to prevent detachment and dissolution of the active materials. Herein, the synthesis of α-MnO2 nanowires on carbon cloth via a simple one-step hydrothermal process and its electrochemical performance, as a binder-free cathode in aqueous and nonaqueous-based ZIBs, is duly reported. Morphological and elemental analyses reveal a single crystal α-MnO2 having homogeneous nanowire morphology with preferential growth along {001}. It is significant that analysis of the electrochemical performance of the α-MnO2 nanowires demonstrates more stable capacity and superior cyclability in a dimethyl sulfoxide (DMSO) electrolyte ZIB than in an aqueous electrolyte system. This is because DMSO can prevent irreversible proton insertion as well as unfavorable dendritic zinc deposition. The application of the binder-free α-MnO2 nanowires cathode in DMSO can promote follow-up research on the high cyclability of ZIBs.

Nonaggregate and well-crystallized Co 3 O 4 nanoparticles with size of 5–15 nm were prepared on a large scale at low temperature by an epoxide precipitation route. The preparation of Co 3 O 4 nanoparticles followed the steps of α- Co ( OH )2 formation through epoxide precipitation reactions, conversion of α- Co ( OH )2 to CoOOH in ammonia regulated alkaline suspension, and transformation of CoOOH to Co 3 O 4 at 100°C. The small size and nonaggregate state of obtained Co 3 O 4 nanoparticles guaranteed the full contact of Co 3 O 4 nanoparticles with electrolyte and the complete penetration of electrolyte into the particles. Consequently, the Co 3 O 4 nanoparticles presented specific capacitance as high as 879.5 F g-1 at scan rate of 5 mV s-1 in 1 KOH . Their specific capacitance remain 82.8% of the initial specific capacitance after 5000 charge and discharge cycles. These results demonstrated that these Co 3 O 4 nanoparticles can be applied as a high performance electrode material for supercapacitor.
