“…According to the reported work, there exists two charging/discharging process for MnO x anode materials. 39,40 However, as far as we know, there is little work have been reported demonstrating the mechanism of the two charging/discharging process of MnO 2 . Herein, it is going to be further discussed.…”

“…To deeply understand the mechanism, the reduction process has been closely monitored through the specific cyclic voltammogram (CV) measurements (Figure f) . As shown in the CV curves of Ti 4 Mn 3 -cluster under Ar and CO 2 atmosphere, the obvious reductive wave at about 0.08 V is assigned to the reduction of Mn 2+ to Mn 0 . − This low-valence Mn species is regarded as the intermediate in the process of the photocatalytic CO 2 reduction reaction, which can be stabilized by the ligands coordinated to Mn centers in Ti 4 Mn 3 -cluster. Under a CO 2 atmosphere, low-valence Mn 0 species take part in the reduction of CO 2 , characterized by the obviously increased current density at −0.85 V compared to the current density under an Ar atmosphere.…”

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.
