SnO 2 -based nanomaterials: synthesis and application in lithium-ion batteries and supercapacitors

Abstract

Tin dioxide (SnO2) is an important n-type wide-bandgap semiconductor, and SnO2-based nanostructures are presenting themselves as one of the most important classes due to their various tunable physicochemical properties. In this paper, we firstly outline the syntheses of phase-pure SnO2 hierarchical structures with different morphologies such as nanorods, nanosheets, and nanospheres, as well as their modifications by doping and compositing with other materials.Then, we reviewed the design of SnO2- based nanostructures with improved performance in the areas of lithium-ion batteries (LIBs) and supercapacitors.
