“…Clearly, all the diffraction peaks of two samples are consistent with the standard card of hexagonal Mn 2 Sb 2 O 7 (JCPDS No. Sb ion is coordinated with six oxygen ions forming the SbO 6 Raman spectrum of the samples (Figure 1c) was also studied to determine the presence of RGO. No peaks of RGO are observed in the diffraction peaks of the Mn 2 Sb 2 O 7 /RGO composite, which may be attributed to the large amount of Mn 2 Sb 2 O 7 restraining the re-stacking of graphene.…”

“…In order to improve energy density of LIBs, many anode materials, especially metal oxides (such as SnO 2 , Sb 2 O 3 , Fe 2 O 3 , TiO 2 , and Bi 2 O 3 ) with large reversible Li + storage capacities, have been studied. [6][7][8][9][10] By virtue of its high specific capacity (theoretically 1109 mAh g À 1 ), Sb 2 O 3 has been investigated as a promising anode for LIBs based on conversion and alloying reactions. [11,12] However, the rapid capacity fading and poor reversibility of Sb 2 O 3 are observed initially because of large volume changes upon cycling.…”

For the advancement of lithium-ion batteries (LIBs), metal oxides with high theoretical specific capacities have been explored as anodes. Herein, we report a new metal oxide, Mn 2 Sb 2 O 7 -anchored reduced graphene oxide (Mn 2 Sb 2 O 7 /RGO), as an advanced anode for LIBs. The Mn 2 Sb 2 O 7 /RGO anode exhibits a higher capacity and better capacity retention compared to Mn 2 Sb 2 O 7 , because the close contact between Mn 2 Sb 2 O 7 and RGO facilitates charge transfer during cycling.The discharge capacity of Mn 2 Sb 2 O 7 /RGO reaches 706.72 mAh g À 1 at 200 mA g À 1 after 200 cycles. Even at 1000 mA g À 1 , the capacity loss per cycle of Mn 2 Sb 2 O 7 /RGO is only 0.0344 % for 600 cycles, indicating an excellent high-rate cyclic stability compared to other Sb-based oxides. These results forecast that Mn 2 Sb 2 O 7 /RGO is a potential anode for LIBs, providing a new insight into the selection of high-performance anodes.

“…[48] The post-SEM image of the Ni 3 N@Ni 3 S 2 electrode showed only slight cracks after 200 cycles, indicating its outstanding structural stability ( Figure S8a, Supporting Information). [52,53] Li 2 O should not be detected because metal oxides are not present in the electrode. Similar to Ni 3 N@Ni 3 S 2 , the Ni 3 N also showed good stability with enhanced discharge capacity and cracks and little pulverization in its post-storage performance SEM image ( Figure S8c, Supporting Information).…”

trode materials for the replacement of the conventional graphite. [1][2][3][4][5][6] However, they suffer from a variety of problems such as poor conductivity for the oxides/ hydroxyls/sulfides and bad structural stability for the nitrides. [7][8][9][10][11] Some of the common methods used to solve the above problems include nanostructuring, [12] carbon coating, [13,14] mixing with carbonbased materials, [15,16] and the construction of TMC composites. [17,18] The preparation of TMC composites usually combines the advantages of each material, leading to synergistic effect. [19][20][21] According to the study by J. Maier, the phase interface present in a composite often leads to lattice mismatch and therefore creates more active sites for energy storage, enabling the electrodes to exceed their theoretical capacity. [22,23] Moreover, the lattice mismatch is also beneficial for the transformation of lithium ions and electrons, which could also result in the improved rate performance. On the other hand, the predominant pseudocapacitive processes in lithium-ion batteries make active materials show better rate capability. [24] Many electrode materials such as MoO 3 , [25] SnO, [26] and SnS [27] have been found with excellent pseudocapacitive characteristics both in lithium and sodiumion batteries because these materials store more energy at the surface or near surface of the material by Faradaic charge transfer. [1] Pseudocapacitance materials can either be intrinsic (i.e., storage properties not based on particle sizes and morphologies such as RuO 2 and MnO 2 ) or extrinsic (i.e., storage properties based on the preparation of porous or nanometersized active materials such as V 2 O 5 and MoO 2 ). [27] Moreover, pseudocapacitive contributions have been obtained in some insertion, conversion, and alloying reaction of individual or single electrode materials, while their application in composites has been less studied. [28] In view of advances of various TMC composite electrodes, it is highly challenging to study their relationship to pseudocapacitance contributions.Among the commonly reported electrode materials with pseudocapacitive properties, nickel-based materials (NiO, Ni 3 S 2 , and Ni 3 N) have attracted intense attention due to their low cost and theoretical capacity higher than that of conventional graphite. [29] Several strategies have been employed to improve the performance of energy storage devices through the development of new electrode materials. The construction of transition metal compound composite electrodes plays an important role in promoting the performance of energy storage devices. However, understandings of and insight into how to enhance the composites properties are rarely reported. Taking nickel-based compounds as an example, Ni 3 N@ Ni 3 S 2 hybrid nanosheets are reported as a high-performance anode material for lithium-ion batteries that delivers higher lithium storage properties than the pristine Ni 3 N and Ni 3 S 2 electrodes. This demonstrates that the phase boundaries between the Ni 3 N...

developing new advanced anode materials with compatible high specific capacity and long-lived cycling is still under way.In recent years, transition-metal oxides (TMOs), as anode materials of LIBs, receive great attention because of their ultrahigh theoretical specific capacity, abundant resources, and low cost. [6] However, the decrease of mechanical strength of bulk material, [7] resulting from large volume change during long-term cycling, almost leads to poor electronic transport and cyclability. An effective method to mitigate the mechanical stress/ strain and decrease is to fabricate nanostructured electrodes, such as nanoparticles, [8][9][10] nanowires or nanofibers, [7,11,12] and nanosheets. [13][14][15] Further improvement can be achieved with nanostructured materials by introducing high porosity. Porous nanostructure is assumed to enlarge the contact area between electrode and electrolyte, supply more active sites for lithium storage, and provide mesoporous channels for rapid Li + diffusion, resulting in the enhancive cyclic stability and reversible capacity of materials. [16][17][18] More importantly, the enhanced surface and interface in nanoporous materials can efficiently improve the interfacial (surface) lithium storage, which is capable to offset the capacity loss. Additional Li can be accommodated at both the solid-liquid interface and the solid-solid interface of the nanosized particles.Superior to binary metal oxides, the role of interfacial Li storage seems more prominent for ternary metal oxides based on the conversion mechanism, [19][20][21][22] in which large interfaces are easy obtained after electrochemical cycles. Such conversion often leads to the formation of nanosized hybrids (mixed metal oxides or metals) and "in situ" construction of novel secondary architecture spontaneously. [23][24][25][26][27] It is notable that the reconstructed structure of the electrode may play a vital role in satisfactory electrochemical performance. [28] For instance, hierarchical RGO reduced graphene oxide (RGO)-supported manganese oxide nanoclusters were formed during lithiation/ delithiation of RGO-MnO-RGO sandwich nanostructures, resulting in the ever-increasing capacitance for ultrahigh-rate lithium storage. [27] Porous nanosheets composed of NiMn 2 O 4 /C exhibit a superior specific capacity and an excellent long-term cycling performance owing to its refined porous clusters during cycling. [24] Thus, it is a desirable approach to achieve excellent Li-storage performance via in situ electrochemical reconstruction of ternary TMOs with proper nanostructures.As one of ternary TMOs, Co 3 V 2 O 8 has recently been noticed as the most considerable electrode materials as high performance In order to realize high performance electrode for long-lived lithium ion batteries (LIBs), engineering microstructures of electrode materials, especially porous, hollow, and hierarchical nanostructures, holds great promise in preventing the capacity fading stem from mechanical stress and volume change. Here, this paper repor...
