“…Two slopes appear in the first discharge curve. The first slope between 1.5 and 0.3 V may be attributed to SEI formation and the reduction of Mn 3 O 4 to MnO . The steady discharging plateau at 0.3 V, followed by a gradual decrease to 0.01 V, mainly results from the reduction of MnO to Mn .…”

The practical applications of Mn O in lithium-ion batteries are greatly hindered by fast capacity decay and poor rate performance as a result of significant volume changes and low electrical conductivity. It is believed that the synthesis of nanoscale Mn O combined with carbonaceous matrix will lead to a better electrochemical performance. Herein, a convenient route for the synthesis of Mn O nanoparticles grown in situ on hollow carbon nanofiber (denoted as HCF/Mn O ) is reported. The small size of Mn O particles combined with HCF can significantly alleviate volume changes and electrical conductivity; the strong chemical interactions between HCF and Mn O would improve the reversibility of the conversion reaction for MnO into Mn O and accelerate charge transfer. These features endow the HCF/Mn O composite with superior cycling stability and rate performance if used as the anode for lithium-ion batteries. The composite delivers a high discharge capacity of 835 mA h g after 100 cycles at 200 mA g , and 652 mA h g after 240 cycles at 1000 mA g . Even at 2000 mA g , it still shows a high capacity of 528 mA h g . The facile synthetic method and outstanding electrochemical performance of the as-prepared HCF/Mn O composite make it a promising candidate for a potential anode material for lithium-ion batteries.

“…As shown in Figure 4b, nitrogen adsorption/desorption isotherms of Mn 3 O 4 and Mn 3 O 4 @NC Nrs were conducted at 77 K. The isotherms of the Mn 3 O 4 @NC Nrs exhibit the type IV profile with an H3 hysteresis loop ranged from 0.2-0.95 P/P 0 , consistent with the pore size distribution, which imply the present of typical mesoporous. [36] The Mn 3 O 4 @NC Nrs possesses a higher specific surface area than the pure Mn 3 O 4 because of the generation of mesopores. It is believed that NC layer is contributed to the specific surface area and the pore width, which influence the electrochemical property.…”

Rechargeable aqueous zinc-ion batteries (ZIBs) have attracted escalating attention recently, owing to their energy density, decreasing cost, advanced safety, and environmental benignity. Nevertheless, ZIBs still lack suitable cathode materials with stable cycling performance, owing to the high polarization of zinc ion. Therefore, developing candidate materials with excellent properties remains a great challenge. Herein, we successfully synthesize a novel Mn 3 O 4 @N-doped carbon matrix composite nanorods (Mn 3 O 4 @NC Nrs) by using MnOOH nano-rods (the self-sacrifice templates) and polypyrrole (carbon and nitrogen source). Benefiting from the N-doped carbon shell and the synergetic effect of Zn 2 + and Mn 2 + in the electrolyte, the Mn 3 O 4 @NC Nrs show superior cycling stability and long cycling features for ZIBs. Specifically, the zinc cell conducts a high reversible capacity of 280 mAh g À 1 at 100 mA g À 1 and retains a high reversible capacity of 97 mAh g À 1 at 1000 mA g À 1 after 700 cycles. In addition, the work provides a new approach to fabricate long-term and high-rate capability cathodes for ZIBs.[a] M.

Presently, the negative electrodes of lithium-ion batteries (LIBs) are constituted by carbon-based materials, which exhibit a limited specific capacity 372 mAh g−1 associated with the cycle in the composition between C and LiC6. Therefore, many efforts are currently made towards the technological development of nanostructured graphene materials because of their extraordinary mechanical, electrical, and electrochemical properties. Recent progress on advanced hybrids based on graphene oxide (GO) and reduced graphene oxide (rGO) has demonstrated the synergistic effects between graphene and an electroactive material (silicon, germanium, metal oxides (MOx)) as electrode for electrochemical devices. In this review, attention is focused on advanced materials based on GO and rGO and their composites used as anode materials for lithium-ion batteries.
