SnO₂‐Based Nanomaterials: Synthesis and Application in Lithium‐Ion Batteries and Supercapacitors

Abstract

Tin dioxide (SnO 2 ) is an important n‐type wide‐bandgap semiconductor, and SnO 2 ‐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 SnO 2 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 SnO 2 ‐based nanostructures with improved performance in the areas of lithium‐ion batteries (LIBs) and supercapacitors.
