Apart from the electrochemical performance and unique structural properties of JF/SiNP anodes, what sets them apart from conventional silicon-carbon composites are the carbon precursor and synthesis method. The selection of a carbon precursor for commercial use must balance the need for high-performance and cost-effectiveness with the potential negative impacts on the environment and society. Notably, the true sustainability of the different families of carbon precursors used for these anodes must be carefully evaluated. Commonly used petroleum-based, coal-based, biomass-based, and synthetic carbon precursors all have their own unique properties and characteristics that make them suitable for different silicon-carbon composite anode applications, but they also have various environmental, social, and economic trade-offs that must be considered.
