“…The dealloying of Li x Sn accounts for the anodic peaks appearing between 0.1 and 0.75 V. The anodic peaks appearing at 1.3 and 2.5 V may account for the formation of traces of copper or cobalt oxides during the first charge for the presence of O element in the sample (see Figure c). , In addition, their corresponding reduction peaks appear at 1.25 and 2.1 V on the discharge curve of the second and third circles. Thus, the possible reaction mechanisms in the electrode are as follows ,− …”

Herein, we present the facial preparation of one-dimensional nanoscale square rod array Sn−Co−Cu alloy films through electrodeposition and subsequent annealing methods under the template-free condition, and their electrochemical performances of the assembled lithium cells as anode were tested in detail. The results indicated that the anodes displayed an excellent cyclic performance. The discharge capacities of the anodes were 1072 and 897 mA h g −1 at the corresponding current densities of 200 and 2000 mA g −1 after 500 cycles, with a high capacity retention of ∼92.3%. Moreover, the excellent capacity reversibility was confirmed when cycled at multiple C-rates of 0.2, 0.5, 1.0, 2.0, and 5.0 and then 0.2, and 5.0 A g −1 . This attractive electrochemical characteristic is likely due to the anode with morphology of the nanoscale square rod array. Such structure can accommodate the volume expansion of Sn−Co−Cu alloy film anodes and offer large surfaces and more active sites. The kinetic process of Li + lithiation and delithiation was also characterized based on cyclic voltammetry experiments in a lithium cell whose anode was the Sn−Co−Cu nanoscale square rod array film. The results showed that the kinetics process was mainly dominated by semi-infinite linear diffusion and surface reaction and that the contribution of pseudocapacitance increased with the increase of scan rate.

“…At present, two approaches are commonly adopted. An effective solution is to add elements passivated by Li + , such as Co, 13−15 Ni, 16,17 and Cu. 18,19 Another important one is to grow the nanoarray directly onto current collectors.…”

“…Current commercial graphite anodes have an unsuitably low theoretical capacity of 372 mAh/g [ 3 , 4 ]. Therefore, other anode materials with higher capacity such as Si, Sn, SnO 2 , and Li have attracted interest [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ].…”

“…Recently, many attempts have been made to minimize the larger volume change and internal stress of the Sn anode. Zhang et al manufactured a Sn–Ni–Cu alloy by electrodeposition and subsequent heat treatment, which enhanced electroconductivity and effectively buffered the volume change of the Sn anode [ 10 ]. Polat et al reported that the multilayer cycle performance of a Ni–Sn–C anode was enhanced by Ni and C, which also increased resistance against volume expansion [ 11 ].…”

Sn is a promising candidate anode material with a high theoretical capacity (994 mAh/g). However, the drastic structural changes of Sn particles caused by their pulverization and aggregation during charge–discharge cycling reduce their capacity over time. To overcome this, a TiNi shape memory alloy (SMA) was introduced as a buffer matrix. Sn/TiNi SMA multilayer thin films were deposited on Cu foil using a DC magnetron sputtering system. When the TiNi alloy was employed at the bottom of a Sn thin film, it did not adequately buffer the volume changes and internal stress of Sn, and stress absorption was not evident. However, an electrode with an additional top layer of room-temperature-deposition TiNi (TiNi(RT)) lost capacity much more slowly than the Sn or Sn/TiNi electrodes, retaining 50% capacity up to 40 cycles. Moreover, the charge-transfer resistance decreased from 318.1 Ω after one cycle to 246.1 Ω after twenty. The improved cycle performance indicates that the TiNi(RT) and TiNi-alloy thin films overall held the Sn thin film. The structure was changed so that Li and Sn reacted well; the stress-absorption effect was observed in the TiNi SMA thin films.

Rechargeable lithium-ion batteries (LIBs) are important energy storage devices, widely used in portable electronic products, hybrid electric vehicles, and smart grids. [1][2][3][4][5] However, the cycle stability of LIBs cannot meet the requirements of electric vehicles. Commercial carbon is the most widely used anode material of LIBs, but it is affected by low voltage and lithium dendrite formation. [6][7][8] Therefore, it is of great significance to develop LIB anode materials with high safety and good stability.Li 4 Ti 5 O 12 with spinel structure is a potential anode material for LIB exchange, thanks to its unique structural stability, zero volume change, as well as its relatively stable and high potential plateau (about 1.55 V) during Li þ deinsertion/insertion to reduce the formed lithium dendrite. [9][10][11][12] However, the poor electronic conductivity of Li 4 Ti 5 O 12 and its low ion-diffusion coefficient limit its large-scale application. [13,14] Therefore, overcoming the shortcomings of Li 4 Ti 5 O 12 is of great significance to advanced uses. [13,15,16] Several methods have been utilized to enhance the conductivity of Li 4 Ti 5 O 12 , including doping with various metal ions (Mn 4þ , Zr 4þ , and F À ), [17][18][19][20] combined with highly conductive materials (C and Cu, etc.) [16,[21][22][23][24][25][26][27][28] and the reduction in size through the synthesis of nano-Li 4 Ti 5 O 12 . [29][30][31] The vanadium-based compounds generally exhibit good chemical stability and better safety characteristics in LIBs. [32,33] Among them, numerous copper vanadium oxides with different structures, such as Cu 2 V 2 O 7 , Cu 3 V 2 O 8 , and CuV 2 O 6 , have recently been tested due to their high redox potentials and simple synthesis methods. [34][35][36] Among these, Cu 2 V 2 O 7 made of an orthorhombic system with space group Fdd2 and lattice parameters (a ¼ 2.0645 nm, b ¼ 0.8383 nm, c ¼ 0.6442 nm, α¼ 90 ∘ , β¼ 90 ∘ , γ¼ 90 ∘ ) has been tested as anode material of LIBs for the reasons of low cost, superior energy density, and excellent specific capacity. Applied in the first discharge process of LIBs, Cu 2 V 2 O 7 will produce metallic copper, and produce a voltage window at about 2.5 V, greatly improving the electrical properties of anode materials for LIBs. [37,38] More importantly, Cu in the lower voltage range (1.0À3.0 V) will not be oxidized to copper ions, meaning irreversible anode processes. Therefore, the addition of appropriate
