“…Moreover, when the current density changed back to 0.1 A g −1 after 100 cycles, the MnO 2 @C‐NS nanocomposite could achieve a capacity of 1021 mAh g −1 , demonstrating excellent rate capability. The capacity obtained for MnO 2 @C‐NS nanocomposite is significantly higher than previously reported values (see Table S1, Supporting Information), which might be ascribed to the porous structure of MnO 2 @C‐NS electrode, that offers an easy access to electrolyte ions and generates large number of electroactive sites, resulting in excellent capacity and rate capability …”

Hybrid metal-organic frameworks (MOFs) demonstrate great promise as ideal electrode materials for energy-related applications. Herein, a wellorganized interleaved composite of graphene-like nanosheets embedded with MnO 2 nanoparticles (MnO 2 @C-NS) using a manganese-based MOF and employed as a promising anode material for Li-ion hybrid capacitor (LIHC) is engineered. This unique hybrid architecture shows intriguing electrochemical properties including high reversible specific capacity 1054 mAh g −1 (close to the theoretical capacity of MnO 2 , 1232 mAh g −1 ) at 0.1 A g −1 with remarkable rate capability and cyclic stability (90% over 1000 cycles). Such a remarkable performance may be assigned to the hierarchical porous ultrathin carbon nanosheets and tightly attached MnO 2 nanoparticles, which provide structural stability and low contact resistance during repetitive lithiation/delithiation processes. Moreover, a novel LIHC is assembled using a MnO 2 @C-NS anode and MOF derived ultrathin nanoporous carbon nanosheets (derived from other potassium-based MOFs) cathode materials. The LIHC full-cell delivers an ultrahigh specific energy of 166 Wh kg −1 at 550 W kg −1 and maintained to 49.2 Wh kg −1 even at high specific power of 3.5 kW kg −1 as well as long cycling stability (91% over 5000 cycles). This work opens new opportunities for designing advanced MOF derived electrodes for next-generation energy storage devices.and power density as well as long cycle life at low cost. [1][2][3][4] In this context, a new system called "lithium-ion capacitors (LICs)" is proposed in the beginning of 21st century, which is hybrid arrangement of a battery-like (as anode) and supercapacitor-like electrodes (as cathode) in organic electrolyte, heading to enhance energy and power densities. [5][6][7] It has been emphasized that LIC bridges the low energy density supercapacitors (SCs) and low power Li-ion batteries (LIBs). [8,9] Such an excellent performance of LIC in terms of energy and power density is assigned to the coupling effect from the rapid charging rate of capacitor-type electrode, the large specific capacity of the battery-like electrode, and the much wider working potential window of the organic electrolytes. [5,6] So far, several hybrid LIC designs have been realized, which are based on an activated carbon (AC) cathode combined with graphite, Li 4 Ti 5 O 12 (LTO), vanadates (Li 3 VO 4 , BiVO 4 , etc.), or metal oxides anodes. [10][11][12][13][14][15][16] However, the poor rate capability of graphite, the relatively high redox potential (≈1.5 V, vs Li/Li + ) of LTO, the poor electrical conductivity, and the cycle stability of metal oxides hamper their utilization in high performance LICs. Therefore, it is crucial to explore the novel anode and cathode materials with high rate capability, good cycle stability, and low redox potential to achieve further improvements for hybrid LICs.

“…[47] The steady discharging plateau at 0.3 V, followed by ag raduald ecrease to 0.01 V, mainly results from the reduction of MnO to Mn. [48] There are two slopes in the first charging curve. The first slope between 1.2 and 1.8 Vm ainly results from the oxidation of Mn to MnO, and the second slope, ranging from 1.9t o 2.2 V, is due to the oxidation of MnO to Mn 3 O 4 .…”

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.

“…Up to now, carbon materials and Li 4 Ti 5 O 12 are the two commonly used commercial anode materials, and Si-based anode materials are regarded as most commercial potential materials for next generation LIBs. [1][2][3] Transition metal oxides (TMOs), such as Co 3 O 4 , [4][5][6] Mn 3 O 4 , 7,8 Fe 2 O 3 , 9,10 and NiO 11 also have long been reckoned as potential anode materials for LIBs due to their many attractive features, including high theoretical capacities, high power density and environmental benign. However, these materials inevitably suffer from several major problems: severe volume changes during charge-discharge processes, agglomeration and pulverization of particles, and poor electronic conductivity.…”
