- Abstract
- Multi-walled carbon nanotube (MWNT)/SnO₂nano-composite (MSC) for the anode electrode of a Li-ion battery was prepared using a homogeneous precipitation method with SnCl₂precursors in the presence of MWNT. XRD results indicate that when annealed in Ar at 400℃, Sn6O₄(OH)₄was fully converted to SnO₂phases. TEM observations showed that most of the SnO₂nanoparticles were deposited directly on the outside surface of the MWNT. The electrochemical performance of the MSC electrode showed higher specific capacities than a MWNT and better cycleability than a nano-SnO₂electrode. The electrochemical performance of the MSC electrode improved because the MWNT in the MSC electrode absorbed the mechanical stress induced from a volume change during alloying and de-alloying reactions with lithium, leading to an increase in the electrical conductivity of the composite material.
