“…Clearly, our capacities were higher than or comparable to those of the reported data under the same conditions with less TiO 2 usage. [24][25][26][27]29,33,54,55,[82][83][84][85][86] These performances, on the other hand, also outperformed those of some reported Ti-based multimetallic oxide porous anode materials, such as the 3DOM Li 4 Ti 5 O 12 , mesoporous Li 4 Ti 5 O 12 /C nanocomposite, ordered mesoporous TiNb 2 O 7 , and C-TiNb 2 O 7 composite (Table S1 †), further verifying the superior lithium-ion insertion/extraction performance of the TCN3.…”

In this work, we report the synthesis of several TiO 2 -carbon nanocomposites (TCNs) composed of a homogeneous dispersion of carbon and anatase TiO 2 nanocrystals (30.2-68.7 wt%) in a threedimensionally ordered macroporous framework with a pore-hierarchical structure fabricated by means of a simple multicomponent infiltration of three-dimensionally ordered templates. Galvanostatic charge/ discharge and electrochemical impedance spectroscopy techniques are employed to assess the properties of these nanocomposites for use in lithium ion batteries (LIBs). These results demonstrate that TiO 2 can be effectively utilized with the assistance of the carbon in the electrode. The TCN3 (55.4 wt% of TiO 2 ) is found to be the most efficient one with a high capacity of $549 mA h g À1 at 0.2 C after 100cycles. In addition, it exhibits good cycling stability and superior rate capability as an anode material in LIBs. The reversible capacity can still be retained at $132 mA h g À1 at a high rate of 10 C. Such TCN represents a promising exploring direction for enhancing the device performance of metal oxide-based electrodes in LIBs.

“…Block copolymer templating is a well-established method to synthesize a variety of ordered mesoporous oxides with uniform, well-defi ned pore sizes, [51][52][53][54][55][56][57][58] in both thin fi lm [ 59,60 ] and powder formats. [61][62][63] This preliminary step of creating MoO 2 enables precise control of the nanoscale architecture, however, block copolymer templating cannot be used to directly form sulfi des. Therefore, we use thermal sulfurization in H 2 S to convert the MoO 2 to MoS 2 , which preserves the carefully constructed nanoscale architecture.…”

The ion insertion properties of MoS2 continue to be of widespread interest for energy storage. While much of the current work on MoS2 has been focused on the high capacity four‐electron reduction reaction, this process is prone to poor reversibility. Traditional ion intercalation reactions are highlighted and it is demonstrated that ordered mesoporous thin films of MoS2 can be utilized as a pseudocapacitive energy storage material with a specific capacity of 173 mAh g−1 for Li‐ions and 118 mAh g−1 for Na‐ions at 1 mV s−1. Utilizing synchrotron grazing incidence X‐ray diffraction techniques, fast electrochemical kinetics are correlated with the ordered porous structure and with an iso‐oriented crystal structure. When Li‐ions are utilized, the material can be charged and discharged in 20 seconds while still achieving a specific capacity of 140 mAh g−1. Moreover, the nanoscale architecture of mesoporous MoS2 retains this level of lithium capacity for 10 000 cycles. A detailed electrochemical kinetic analysis indicates that energy storage for both ions in MoS2 is due to a pseudocapacitive mechanism.

kineticreactions. [7][8][9][10] Comparatively speaking, mesopores are more favorable for the transport of reactants or solvents. On the contrary, macropores are too large for common reactants or solvents to be very effective. But if the micropores or macropores are combined with mesopores, the shortcomings will get balanced in a sense because the micropores may enable superior cycle stability and the macropores can promise rapid ion transport when they are employed with mesopores together. Ordered mesoporous materials are generally divided into two kinds: ordered mesoporous siliconbased materials and ordered mesoporous nonsilicon materials. Some ordered mesoporous nonsilicon materials, such as ordered mesoporous metallic materials, nonmetallic materials, ordered mesoporous carbon (OMC)-based materials, and reduced graphene oxide (rGO)-based materials, have aroused widespread interest, among which OMC-based metal composites and metal oxide materials are in the spotlight. [11][12][13] Consequently, OMCbased materials and their applications in various batteries have gradually become popular topics in research (Figure 1a). The rich pore structure and high specific surface area of OMCs are not only beneficial to reactants and product diffusion but also enable the material to incorporate highly dispersed metal nanoparticles. [14][15][16][17] Due to their surface and physicochemical properties, OMCs can easily be subjected to functional group modification or heteroatom doping, thus enhancing the physical and chemical properties of the material. These two points have led to the increasing application of OMC-based materials in electrochemistry.Although the selection of materials is an extremely important aspect, the various types of batteries also have their own advantages and disadvantages. As research progresses, different types of materials have also been applied to various types of batteries to fulfill their potential. [18] Rechargeable lithium-ion batteries (LIBs) play substantial roles in electrochemical energy storage for their advantages of no memory effect, long life cycle, high energy density, and low toxicity, so they are often deemed as clean and renewable sources of energy. [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] However, because of the energy-density limitations of LIBs, such batteries cannot meet the current intensive energy demand. It may be hard for LIBs to satisfy the needs for sufficient power density, high energy density, and long service life in some fields, such as electrical vehicles (hybrid electric Ordered mesoporous materials, porous materials with a pore size of 2-50 nm which are prepared via the sol-gel process using surfactant molecular aggregates as a template to assemble channels through the interfacial action of organic and inorganic substances, have recently triggered a heated debate. In addition to applications in the catalytic cracking of heavy oils and residues, the manufacturing of graft materials, the purification of water, the conversion of automobile exhaust...
