“…For instance, carbon‐coated TiO 2 (B) nanosheet assembled nanospheres flower, Mn‐doped TiO 2 nanosheet‐based spheres, and flower‐like hydrogenated TiO 2 ‐B nanostructures, etc. In addition, many other nanosheet‐based hierarchical structures have demonstrated effective configurations for more enhanced electrochemical performance than that of traditional TiO 2 ‐B architecture, such as the TiO 2 (B)‐C hollow microspheres, branched TiO 2 ‐B architectures, graphene‐supported TiO 2 ‐B nanosheets, molecularly coupled TiO 2 sheets and Ti 3 C 2 sheets, etc. The superior electrochemical performance of TiO 2 ‐B strongly correlates to the synergetic superiorities with a combination of TiO 2 ‐B polymorph, hierarchically micro/nanostructure and interconnected nanosheets.…”

The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/smll.201904740.Titanium-based oxides including TiO 2 and M-Ti-O compounds (M = Li, Nb, Na, etc.) family, exhibit advantageous structural dynamics (2D ion diffusion path, open and stable structure for ion accommodations) for practical applications in energy storage systems, such as lithium-ion batteries, sodium-ion batteries, and hybrid pseudocapacitors. Further, Ti-based oxides show high operating voltage relative to the deposition of alkali metal, ensuring full safety by avoiding the formation of lithium and sodium dendrites. On the other hand, high working potential prevents the decomposition of electrolyte, delivering excellent rate capability through the unique pseudocapacitive kinetics. Nevertheless, the intrinsic poor electrical conductivity and reaction dynamics limit further applications in energy storage devices. Recently, various work and in-depth understanding on the morphologies control, surface engineering, bulk-phase doping of Ti-based oxides, have been promoted to overcome these issues. Inspired by that, in this review, the authors summarize the fundamental issues, challenges and advances of Ti-based oxides in the applications of advanced electrochemical energy storage. Particularly, the authors focus on the progresses on the working mechanism and device applications from lithium-ion batteries to sodium-ion batteries, and then the hybrid pseudocapacitors. In addition, future perspectives for fundamental research and practical applications are discussed. www.advancedsciencenews.com

“…It has also been reported that the graphene improves the thermal stability of the hybrid electrode and prevents the phase transformation in TiO 2 ; i.e., from monoclinic [TiO 2 (B)] to anatase. 179 The specific capacities in the TiO 2 -(B)/graphene hybrid were observed to be 215, 182, and 150 mA h g −1 at the current rates of 1, 5, and 10 C, respectively. On the other hand, bare TiO 2 (B) exhibited specific capacities of 184, 121, and 99 mA h g −1 at 1, 5, and 10 C, respectively.…”

Today, one of the major challenges is to provide green and powerful energy sources for a cleaner environment. Rechargeable lithium-ion batteries (LIBs) are promising candidates for energy storage devices, and have attracted considerable attention due to their high energy density, rapid response, and relatively low self-discharge rate. The performance of LIBs greatly depends on the electrode materials; therefore, attention has been focused on designing a variety of electrode materials. Graphene is a two-dimensional carbon nanostructure, which has a high specific surface area and high electrical conductivity. Thus, various studies have been performed to design graphene-based electrode materials by exploiting these properties. Metal-oxide nanoparticles anchored on graphene surfaces in a hybrid form have been used to increase the efficiency of electrode materials. This review highlights the recent progress in graphene and graphene-based metal-oxide hybrids for use as electrode materials in LIBs. In particular, emphasis has been placed on the synthesis methods, structural properties, and synergetic effects of metal-oxide/graphene hybrids towards producing enhanced electrochemical response. The use of hybrid materials has shown significant improvement in the performance of electrodes.

“…In this context, various carbonaceous materials, e.g., activated carbon fabrics, [ 39 ] carbon coatings, [ 40 ] carbon nanotubes, [ 41 ] or graphene nanosheets, [42][43][44][45] are introduced as conductive additives to ease the electron transport, thereby improving the cycle performances of TiO 2 (B) at high rates. Despite this progress, the reversible capacity of TiO 2 (B) is still insuffi cient, especially when compared to other TMOs, such as Fe 2 O 3 , [46][47][48][49][50] SnO 2 , [51][52][53][54] Co 3 O 4 , [ 55 ] and MnO 2 , [ 56 ] all of which boast of their much higher theoretical capacities (800−1200 mA h g −1 ) than TiO 2 (B).…”

and transition metal oxides (TMOs) [13][14][15][16] have recently been explored as promising anode candidates.TiO 2 , among other TMOs, is particularly attractive owing to its fascinating features including high structural stability, long cycle life, low cost, and high safety. [17][18][19][20][21] TiO 2 (B), as an unusual polymorph (bronze-phase) of TiO 2 , is found to have an open-channel structure and display a pseudo-capacitive behavior, thus enabling easier Li + diffusion and faster chargingdischarging capabilities. [ 22 ] Its theoretical capacity (335 mA h g −1 ) therefore significantly surpasses that (≈170 mA h g −1 ) of anatase or rutile TiO 2 , and is comparable to that (372 mA h g −1 ) of graphitic carbons. In consequence, various TiO 2 (B) nanostructures in the form of, e.g., nanoparticles, [23][24][25] nanorods, [ 26,27 ] nanowires, [28][29][30][31] nanotubes, [32][33][34][35][36] or nanosheets, [ 37,38 ] have been intensively studied as LIB anodes.It is worth noting, however, that the poor intrinsic conductivity of TiO 2 (B) inevitably sets obstacles for its applications as a high-power anode material. In this context, various carbonaceous materials, e.g., activated carbon fabrics, [ 39 ] carbon coatings, [ 40 ] carbon nanotubes, [ 41 ] or graphene nanosheets, [42][43][44][45] are introduced as conductive additives to ease the electron transport, thereby improving the cycle performances of TiO 2 (B) at high rates. Despite this progress, the reversible capacity of TiO 2 (B) is still insuffi cient, especially when compared to other TMOs, such as Fe 2 O 3 , [46][47][48][49][50] SnO 2 , [51][52][53][54] Co 3 O 4 , [ 55 ] and MnO 2 , [ 56 ] all of which boast of their much higher theoretical capacities (800−1200 mA h g −1 ) than TiO 2 (B).In this work, we expect to address the conductivity and capacity defi ciencies of TiO 2 (B) through a smart morphological and compositional design, aiming to achieve excellent reversible capacities and rate capabilities at the same time. Here we report elaborately designed hierarchical heterostructures, consisting of carbon-coated TiO 2 (B) nanosheets decorated with Fe 3 O 4 nanoparticles, based on a one-step self-assembly strategy through van der Waals interactions. [ 57 ] We stress that compared to other hybridization approaches based on hydrothermal synthesis, [46][47][48][50][51][52][53]55,56 ] atomic layer deposition, [ 49 ] and thermal pyrolysis, [ 54 ] our one-step self-assembly strategy is really facile and energy-effi cient, since it does not require harsh
