“…Lidelithiation), the cathodic peak is located at 0.13 V, whereas the corresponding anodic peak is 0.57 V. These indicate that the delithaition reaction occurs at around 0.57 V and that peak for the lithiation reaction appears at around 0.13 V. In subsequent cycles, the cathodic peak moves to lower potential of 0.01 V and the anodic peak shifts to lower potentials around 0.5 V, respectively. Consistent with existing literature, [22][23][24][25] the cathodic peaks at 0.13 V (first cycle) and 0.01 V (subsequent cycles) are attributed to lithiation of SiO and Si, respectively, while the anodic peaks at 0.57 V (first cycle) and 0.5 V (subsequent cycles) are attributed to delithiation of Si.…”

Silicon monoxide (SiO) is utilized as an anode material in Li-ion batteries. The electrochemical properties of the SiO anodes are investigated. The SiO exhibits a high initial capacity of~2083 mAh g −1 , while it has poor cycling stability. Thermal properties of SiO electrodes in mixing with or without the electrolyte are investigated by using DSC for the first time. Both lithiated and delithiated SiO electrodes show exothermic peaks in DSC curves, presumably due to the decomposition of electrodes. By changing the ratio between the cycled electrodes to the electrolytes, thermal behavior of the mixtures is studied in detail. The dominant exothermic peak at around 290°C is attributed to the reactions between lithiated electrode and electrolyte after the thermal breakdown of the SEI. Li in the electrodes and electrolytes should be responsible for the thermal risk in application of SiO batteries. The heat value of SiO based on capacity is estimated to be 1.85 J mAh ). Hence, the SiO can be thermally safer than graphite.

“…Furthermore, the EDS mapping in Figure 3 shows that the Si, Zr, and O elements were all uniformly dispersed without agglomeration. [26,27]. Therefore, the combined peak from 0.18 show similar impedance shapes, with one depressed semicircle at high frequency and an inclined line at low frequency.…”

In this article, a novel anode material with high electrochemical performance, made of elements abundant on the Earth, is reported for use in lithium ion batteries. A chemically synthesised material (SiO 2 /ZrO 2 ) containing Si-O-Zr bonds, exhibits as much as 2.1 times better electrochemical performance at the 10 th cycle than a physically mixed material (SiO 2 +ZrO 2 ) of the same elements. When compared to synthesized SiO 2 or conventional graphite-based electrodes, the SiO 2 /ZrO 2 anode shows superiorcapability and cycling performance. This superior performance is ascribed to the effect of ternary compounds, which contributes not only to increasing the packing density, but also to creating the Si-O-Zr bond that makes additional reactions between SiO 2 /ZrO 2 and lithium ions possible. The Si-OZr bond also contributes to improved conductivity for SSZ and provides facile paths for charge transfer at the electrode/electrolyte interface. Therefore, the overall internal resistance in a battery would be decreased and better performance could thus be obtained, with this type of anode. In every result, the positive influence of the Si-O-Zr bonds in the anode of a lithium ion battery was confirmed.

“…Silicon monoxide/graphite/multiwalled carbon nanotubes (SiO/G/CNTs) material prepared by ball milling followed by chemical vapor deposition method exhibited an initial specific discharge capacity of 790 mAh g À1 with a columbic efficiency of 65 %. After 100 cycles at a constant current density of 230 mA g À1 , a high reversible capacity of 495 mAh g À1 was still retained [419]. A novel SiO/graphene composite exhibited a high initial specific capacity of 2285 mAh g À1 , excellent cyclic performance of 890 mAh g À1 at 100th cycle and good rate capability, which was ascribed to the three-dimensional architecture of SiO/graphene nanocomposite [420].…”

Lithium-ion batteries (LiBs) have made considerable progress since the first commercial one by Sony in 1991, which had LiCoO 2 and graphite as active elements of the positive and negative electrodes, respectively. The LiBs are now the primary energy storage devices in the transportation and communications, from portable use in computers, up to electric and hybrid vehicles. More recently, they have also been used as back-up supply units, frequency regulators (load leveling) to integrate on smart grids the electricity produced by windmills and photovoltaic plants (for a recent review, see [1]). These applications require high energy densities, high power, and safety among others. Considerable efforts have been made to propose other electrodes to fulfill these requirements. We have recently reviewed the works and progress concerning the materials for the positive electrode [2][3][4][5][6]. The present work is devoted to the materials for the negative electrode counterpart. It is common to use the terminology anode and cathode for the negative and positive electrodes, respectively, although the electrodes play alternatively the role of anode and cathode during the charge and discharge process. We shall use this terminology in the following for conciseness purposes only.An ideal active anode element should fulfill the following requirements as follows: (1) It must be light and accommodate as much Li as possible to optimize the gravimetric capacity. (2) Its redox potential with respect to Li 0 /Li + must be as small as possible at any Li-concentration. The reason is that this potential is subtracted to the redox potential of the cathode material to give the overall voltage of the cell, and smaller voltage means smaller energy density. (3) It must possess good electronic and ionic conductivities since faster motion of the lithium ions and the electrons also mean higher power density of the cell. (4) It must not be soluble in the solvents of the electrolyte and not react with the lithium salt. (5) It must be safe, i.e. avoid any thermal runaway of the battery, a criterion that is not independent of the previous one, but deserves special attention, especially for use in transportation such as electric vehicles and planes. (6) It must be cheap and environmentally friendly. The different materials proposed as anode elements for Li-ion batteries must be discussed with respect to these different criteria.The graphite is still the most used anode material and is still the reference. The first works giving evidence of the insertion of lithium in graphite date from 1955 [7], confirmed by the synthesis of LiC 6 in 1965 [8]. The synthesis of LiC 6 , however, was not obtained by electrochemical process at that time. Another decade was spent before Besenhard and Eichinger discovered the reversible intercalation of lithium in graphite, proposing this material as an anode in 1976 [9,10]. Increasing the Li content in LiC 6 is possible [8], but no reversible cycling beyond LiC 6 could ever be obtained. The graphite anode can thus be cyc...
