High
capacity battery electrodes require nanosized components to avoid
pulverization associated with volume changes during the charge–discharge
process. Additionally, these nanosized electrodes need an electronically
conductive matrix to facilitate electron transport. Here, for the
first time, we report a rapid thermal shock process using high-temperature
radiative heating to fabricate a conductive reduced graphene oxide
(RGO) composite with silicon nanoparticles. Silicon (Si) particles
on the order of a few micrometers are initially embedded in the RGO
host and in situ transformed into 10–15 nm nanoparticles in
less than a minute through radiative heating. The as-prepared composites
of ultrafine Si nanoparticles embedded in a RGO matrix show great
performance as a Li-ion battery (LIB) anode. The in situ nanoparticle
synthesis method can also be adopted for other high capacity battery
anode materials including tin (Sn) and aluminum (Al). This method
for synthesizing high capacity anodes in a RGO matrix can be envisioned
for roll-to-roll nanomanufacturing due to the ease and scalability
of this high-temperature radiative heating process.
