A potential high-capacity anode for lithium-ion battery: carbonized SnO2 nanoparticles

Abstract

Nanomaterials have gained a lot of interest due to their application in various fields. Tin oxide (SnO2) is an important n-type wide band gap semiconductor used as anode in Li-ion batteries due to its high theoretical capacity of 1494mAh/g. Small size of Carbonized SnO2 Np’s can mitigate the problems faced by SnO2 as anode in Lithium-Ion batteries. So, in this work we synthesized SnO2 Np’s of crystallite size ∼30 nm by Sol-gel technique and of crystallite size ∼8 nm, and ∼9 nm by varying pH using Co-precipitation technique and then we carbonized Commercial SnO2, SnO2 Co-precipitation pH8.7, and SnO2 Co-precipitation pH10 using D (+) Glucose. The synthesized SnO2 Np’s and Carbonized SnO2 Np’s were then characterized using Raman Spectroscopy, X-Ray Diffraction, UV Vis Spectroscopy and Scanning Electron Microscopy.
