Current situation

The efficacy of a lithium-ion battery (LIB) hinges significantly on the composition of its anode material.
Presently, graphite stands as the predominant commercial choice for anodes, albeit constrained by its modest capacity.
Silicon, emerging as a frontrunner, presents a promising alternative for the next evolution of lithium-ion batteries, boasting a theoretical specific capacity of 4212 mAh/g—dramatically surpassing graphite's 372 mAh/g.
However, silicon faces the challenge of volumetric expansion ranging from 3–5 times during lithiation–delithiation cycles.
This induces swelling, leading to fissures in the anode material and a breakdown in contact with the current collector. Researchers globally are exploring diverse methodologies to optimise the efficiency of anodes founded on nano-silicon

Current problems with silicon

The mechanisms of LIB degradation are complex and depend on several factors, the main of which is the agglomeration of silicon nanoparticles and its volumetric changes, leading to loss of contact between silicon nanoparticles and carbon material, which leads to degradation of LIB during cycling. The picture shows how silicon is unevenly distributed in the carbon material and forms agglomerates up to 300 nm in size.

This sophisticated procedure induces rapid exfoliation of intercalates and the simultaneous formation of multi-layered graphene. Through energy release and subsequent temperature surges, essential elements undergo thermal decomposition, yielding nano-sized silicon particles that seamlessly integrate with graphene layers.

This nuanced interplay of forces orchestrates the simultaneous exfoliation and the creation of silicon-carbon nano-composites. Meticulous control of precursor selection, gas mixture composition, and pressure conditions enables the crafting of nano-composites with precision, defining size, structure, and silicon nanoparticle content throughout the material.
