Preparation of core-shell Si/NiSi2/carbon composite and its application to lithium secondary batteries

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.…”

Preparation of SixCo0.3Cu0.3Cr0.6Al0.2/modified graphite sphere composites and their electrochemical performance as anode materials for Li-ion batteries

“…Among a variety of anode materials, Si-transition metal systems with a high volumetric capacity have attracted many researchers' interests. So far, some transition metal silicides and alloys such as Ni-Si [7][8][9][10], Mn-Si [11], Cu-Si [12][13][14][15][16], FeSi [17,18], Si-Cr [19], Si-Mn-Al [20], Si-Fe-Cu [21] and Si-AB 5 [22] have been explored mostly with graphite/carbons. In these studies, the improved cycle performance has been obtained compared with elemental Si.…”

Si/C composite lithium-ion battery anodes synthesized from coarse silicon and citric acid through combined ball milling and thermal pyrolysis

“…Currently, various strategies have been exploited for the purpose of increasing the cycling stability of silicon-based electrodes, including reducing the particle size of silicon to the nanometer level [16,17], dispersing the silicon in an inactive or active matrix [18][19][20][21], alloying silicon with other less active elements [22,23], developing Si into thin-film electrodes [24,25], or increasing the electronic contact of silicon with the current collector by optimizing the morphology of the silicon [26,27]. Among these, the dispersion of silicon in an active matrix has attracted particular interest.…”
