“…For instance, the ≈52 and 78.2% initial reversible capacity was noted for bare and diamond‐like carbon‐coated SiO‐graphite composites after 100 cycles, respectively. A high reversible capacity of over 1000 mAh g −1 was noted under elevated temperature conditions (60 °C) with an increase in the upper cut‐off potential, i.e., different working potential 3 to 4, 4.1, and 4.2 V when paired with a layered LiNi 0.8 Co 0.15 Al 0.05 O 2 cathode . However, drastic fading was observed for the potential window of 3 to 4.2 V, whereas notable fading was observed for rest of the potential window.…”

“…An excellent cycleability was seen for both the anode and the cathode in the half-cell assembly, but a capacity fade in full-cell confi guration was observed; for example, reversible capacities of ≈900 and ≈570 mAh g −1 were observed for fi rst and 50 th cycles, respectively. [ 443 ] However, drastic fading was observed for the potential window of 3 to 4.2 V, whereas notable fading was observed for rest of the potential window. [ 440 ] The SiO-carbon composite showed much better electrochemical performance than the SiO-graphite composite in the half-cell assembly and it showed reversibilities of ≈870 and 740 mAh g −1 , for the former and latter cases, respectively.…”

3 of 43) 1402225 wileyonlinelibrary.comhost matrix is observed and this process is called "topotactic reaction", which is either chemically or thermally reversible; a perfect example is Li-intercalation into a graphite matrix. Such intercalation chemistry has been successfully used in Li-ion batteries for both anode and cathode materials and has also been commercialized (i.e., LiCoO 2 /Li x C 6 and LiFePO 4 /Li x C 6 ). [ 4,5 ] The insertion type materials, i.e., metal oxides have several advantages over graphitic anodes when used in practical cells; these include a negligible amount of ICL, no Li-platting issues, no solvent co-intercalation, no electrolyte decomposition, no SEI required for the safe operation of the cell, it is capable of delivering high power density, and has an easy synthesis protocol. On the other hand, less reversible capacity and higher intercalation potential are the notable setbacks compared to graphite. Although numerous Li-intercalating materials are proposed as possible anodes for LIB applications, few of them have only been tested or commercialized in the "rocking-chair" confi guration, for instance Li 4 Ti 5 O 5 anode. Apart from the mentioned anode, few other insertion type materials have been also evaluated in the rocking-chair confi guration for LIBs. Accordingly, the next section describes the structural and electrochemical performance of various intercalation anodes evaluated in the rocking-chair confi guration. TiO 2The existence of several polymorphs is reported for the case of TiO 2 , but anatase, rutile, brookite, and bronze phases have only been reported for Li-storage. [ 26 ] Reversible insertion of one mole of Li is theoretically possible, independent of the polymorph, with a capacity of ≈335 mAh g −1 . However, variation in the Liinsertion potential and reaction mechanism has been observed for such polymorphs. Easy synthesis protocols, scalability, inexpensiveness, ease of tailoring the desired morphology, and eco-friendliness are other key features for utilizing TiO 2 polymorphs for the construction of Li-ion power packs. [27][28][29] AnataseThe anatase phase is one of the widely investigated polymorphs of TiO 2 for Li-storage. [ 27 ] Theoretically, one mole of Li is possible, but practically only ≈0.5 mole Li is reversible upon cycling. Several research attempts have been carried out to improve the reversible capacity, including utilizing high energy (0 0 1) facets because of their dominant higher surface energy (0.90 J m −2 ) compared to (1 0 0) facets (0.44 J m −2 ) and using thermodynamically more stable (1 0 1) facets (0.53 J m −2 ). [ 30,31 ] Although high Li-reversibility could be achieved for such (0 0 1) facets, capacity fading remains an issue upon cycling. [ 32 ] Li-diffusion co-effi cient ( D Li ) values for anatase phase are in the range of 1 × 10 −17 to 4 × 10 −17 cm 2 s −1 for Li-insertion and extraction processes, respectively. [ 27 ] In the crystal chemistry of the anatase phase, TiO 6 octahedra sharetwo adjacent edges with two other octahedral so that...

“…Despite the lower theoretical specific capacity compared to Si, SiO x has also attracted great interest of the industry due to its relatively smaller volume expansion, fewer parasitic reactions with electrolytes, and better cyclability. , To facilitate their practical applications in full-cells, SiO x or SiO x -C composites are paired with various cathode materials including layered oxides (Li 0.8 Mn 0.8 Ni 0.2 O 2.2 , LiCoO 2 , ,, LiNi x Co y Mn 1– x – y O 2 , , LiNi 0.8 Co 0.15 Al 0.05 O 2 , ,− lithium-rich layered oxides , ), olivine LiFePO 4 , , and very recently reported spinel LiMn 2 O 4 and LiNi 0.5 Mn 1.5 O 4 . , These full-cells mainly concentrate on material synthesis, prelithiation technology, cell design/performance evaluation, and deterioration mechanism study, rarely considering the impact of electrolyte functional additives from the perspective of the SEI layer. It is well-known that the use of electrolyte functional additives is one of the most economical, feasible, and effective strategies to significantly improve the performances of LIBs. , Presently, commercial LIBs often contain several functional electrolyte additives that, apparently, can work synergistically together to modify and stabilize the SEI layer, which greatly influences their electrochemical performances and safety. − Fluoroethylene carbonate (FEC) has been proved to be the most effective electrolyte additive for improving the cycling performance of Si-based and SiO x -based electrodes in both half-cells and full-cells. ,,,,− …”

The development of next generation high energy density lithium ion batteries (LIBs) adopting electrode materials with higher specific capacity or higher working voltage has attracted great interest. In this paper, fluoroethylene carbonate (FEC) and 1,3-propanediolcyclic sulfate (PCS) are unprecedentedly combined as hybrid functional additives to significantly improve the performances of a very challenging next-generation high voltage (5 V-class) SiO x -C/ LiNi 0.5 Mn 1.5 O 4 battery system, where SiO x -C composite shows a high specific capacity of 450 mAh g −1 and LiNi 0.5 Mn 1.5 O 4 has a high working voltage plateau (∼4.7 V vs Li + /Li). Combining in situ differential electrochemical mass spectrometry (DEMS) technology, theoretical calculations, and conventional ex situ characterizations, it is revealed that small amounts of lithium-containing species (such as LiF, sulfate species, and organic sulfite species) with excellent electronic-insulating, ionic-conducting, and compact properties are derived from prior decomposition of additives and incorporated into the solid electrolyte interface (SEI) layer of SiO x -C electrode, suppressing the reductive decomposition of carbonate solvents as well as the gas generation (C 2 H 4 , CO 2 , and H 2 ). Moreover, hybrid functional additives are beneficial for forming a compact and homogeneous cathode SEI layer, alleviating dissolution of transition metals, structure degradation, and loss of active lithium. This manuscript provides a very useful research method for understanding the working mechanism of functional additives and will also help us to depict the SEI layer formation mechanism more accurately.

Zn 2 SnO 4-based anode materials have recently attracted considerable attention due to their high capacity and low price for lithium-ion batteries. However, their performance is affected by temperature and temperature-dependent characters have not been investigated sufficiently. In this regard, we tested the electrochemistry performance of Co-doped Zn 2 SnO 4 −graphene−carbon (Co−ZTO−G−C) nanocomposite anode at various temperatures (−25, 25 and 60 °C) and analyzed the main limitations and improvements of its low-and high-temperature behavior. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) results demonstrated that severe concentration polarization, the absence of Zn 2 SnO 4 /Zn(Sn) redox couple and large charge-transfer resistance R ct limited its low-temperature performance. Further electrochemical performance analysis indicated that the doped Co could effectively decrease R ct of the nanocomposite and improve its capacity at low temperature. It also suggested that graphene and carbon layer contributed to maintaining its capacity during high-temperature cycles. Field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD) results revealed that the performance degeneration of the nanocomposite at elevated temperature was mainly attributed to severe volume expansion/contraction of Zn 2 SnO 4 nanoparticles and destruction of Zn 2 SnO 4 cubic structure. The XRD results also showed that the cubic structures of Zn 2 SnO 4 at all temperatures were destroyed after cycling, which led to cyclic performance degeneration of the Co−ZTO−G−C nanocomposite.
