Silicon and Carbon Anode Materials for High-Performance Lithium-Ion Batteries
This research community focuses on developing advanced anode materials, primarily silicon and carbon-based composites, to increase the energy density and stability of lithium-ion batteries.
The work centers on overcoming the mechanical instability of silicon anodes during lithium insertion. Recurring themes include the synthesis of porous silicon, silicon-carbon composites, and graphene oxide coatings to manage volume expansion. Researchers frequently investigate nitrogen-doped carbon structures, carbon nanotubes, and various binder systems to enhance electrical conductivity and structural integrity. The literature is heavily populated with studies on "high-performance" and "enhanced" capacity, often detailing specific synthesis methods like chemical vapor deposition and electrochemical characterization of these electrode materials.
The community is most heavily concentrated in lithium research, accounting for 8.6% of all tracked lithium studies and comprising 19,275 papers. It also represents 1.7% of silicon research (5,934 papers) and 1.2% of carbon research (10,399 papers).
This body of work comprises 22,357 papers, with the highest publication volume in the Journal of Power Sources, Electrochimica Acta, and Journal of Alloys and Compounds.
Recent papers continue to address the core challenges of silicon anode degradation, with new studies exploring solid electrolyte interphase engineering, the recycling of photovoltaic silicon waste into battery anodes, and the mechanistic understanding of interphase-driven ageing in silicon-based electrodes.
