Carbon-coated NiSi alloy?graphite composite as an anode material for lithium-ion batteries

Comparative Study on Performances of Composite Anodes of SiO, Si and Graphite for Lithium Rechargeable Batteries

“…Carbon coating of the composites has also been reported to provide high cycle stability to the anode. 2,[13][14][15] Among silicon-based composites, SiO shows better cycle performance than silicon composites; this is because during the initial lithiation process, the Li2O formed in situ acts as a buffer material, thereby preventing electrode degradation due to large volume changes. Along with Li2O, SiO forms nanometric silicon, which alloys and de-alloys with lithium during the charge/discharge cycles.…”

Electrochemical characterization of Ti–Si and Ti–Si–Al alloy anodes for Li-ion batteries produced by mechanical ball milling

“…Many researchers have investigated various transition metal silicides and alloys such as Fe-Si [1][2][3][4][5][6], Ni-Si [6][7][8][9][10][11], Cu-Si [12][13][14][15][16], Ti-Si [17] and Cr-Si [18]. However, in most of previous studies, the metal silicon alloys were used in a type of carbon composites consisting in the dispersion of small particles of silicon alloys with graphite/carbons as host materials to buffer the volume changes * Corresponding author.…”

A new composite anode, Fe–Cu–Si/C for lithium ion battery

“…In this attempt intermetallic silicide alloys with less active or inactive metal elements with binary alloys such as Ca-Si [3], Ni-Si [4][5][6][7][8][9], Fe-Si [10][11][12], Mn-Si [13][14][15], Co-Si [16], Mg-Si [17,18], Cu-Si [19][20][21][22], Ag-Si [23], Ti-Si [24], Ti-C [25]. Cr-Si [26] and also alloys consisting of multicomponents Si-M (M = Cr + Ni, Fe, Mn) [27], Si-Ba-Fe [28], Si-Nd-Fe-B [29], Si-Fe-Mn [30] and Si-AB 5 (MmNi, Co, Al, Mn) [31] were explored mostly with graphite.…”
