Si/C Composites for High Capacity Lithium Storage Materials

Failure Modes of Silicon Powder Negative Electrode in Lithium Secondary Batteries

“…[5][6][7] For the second problem, Si powders were fabricated as a composite with conductive carbon, metal or ceramic materials. [8][9][10][11][12][13][14][15] The prime concern in this work is the identification of failure modes in Si powder negative electrodes. It is likely that the failure modes are deeply related with severe volume change and poor conductivity.…”

Comparative Quantum Chemical Examination of Lithiation/Delithiation Processes in Sin Nanoclusters and CmSin Nanocomposites

“…Covering silicon micro-or nanoparticles with carbon is shown in [6][7][8][9][10][11][12][13][14] to result in an increase in the reversible capacity and the number of chargedischarge cycles of silicon-carbon (Si/C) electrodes as well as of the Coulomb component of the first cycle. Si/ composites are produced by various methods: powdering silicon mixed with graphite in a ball mill, deposition of carbon atoms from gas phase (or plasma), pyrolysis of a silicon mixture with carbon-containing precursors [15][16][17][18][19][20].…”

Effect of Carbon Matrix on Electrochemical Performance of Si/C Composites for Use in Anodes of Lithium Secondary Batteries

“…Silicon-based carbon composites have been studied intensively. [9][10][11][12][13][14][15][16][17][18] Various approaches to make these materials have included simple blending of silicon and carbon, introducing nano-sized silicon particles into a matrix and coating silicon or silicon composites with conductive materials.…”
