Meso-porous silicon-coated carbon nanotube as an anode for lithium-ion battery
Si, meso-porous, carbon nanotube (CNT), magnesiothermic reduction, battery
Meso-porous Si-coated carbon nanotube (CNT) composite powders wereprepared by combining a sol‒gel method and the magnesiothermic reductionprocess. Meso-porous Si-coated CNT electrodes exhibit excellent cycle and rateperformances as anodes in Li-ion batteries (LIBs), which can be attributed tothe efficient accommodation of volume change from meso-porous Si structureand the enhanced electrical conductivity from CNT core. This simple synthesisand subsequent reduction process provide a scalable route for the large-scaleproduction of Si-C composite nanostructures, which can be utilized in a varietyof applications, such as in photocatalysis, photoelectrochemical cells (PECs),and LIBs.
