Silicon and Carbon Anode Materials for Lithium-Ion Batteries
This community focuses on developing high-capacity anode materials, primarily using silicon and carbon composites, to increase the energy density of lithium-ion batteries.
The research centers on replacing or augmenting standard graphite anodes with silicon-based structures to store more lithium ions. Recurring methods involve synthesizing porous silicon, silicon-carbon composites, and graphene oxide hybrids to manage the physical expansion of silicon during charging. Key applications include fast-charging capabilities, improved cycling stability, and the integration of these anodes into solid-state battery architectures. The work frequently addresses the mechanical failure of silicon anodes and the design of conductive networks using carbon nanotubes or metal oxides to maintain electrode integrity.
The largest share of the community's output is found in lithium research, accounting for 10.6% of all lithium research, with 4,284 papers. Silicon research also represents a significant portion, contributing 6.7% of its total research volume with 2,507 papers.
The community comprises 11,248 papers, published most frequently in the Journal of Power Sources, Electrochimica Acta, and Journal of Alloys and Compounds.
Recent work continues to focus on mitigating volume expansion in silicon anodes, with specific studies exploring size effects, charge transport in silicon-carbon anodes, and thermal runaway mechanisms in high-energy battery systems.
