Facile one-step synthesis of a 3D macroscopic SnO2–graphene aerogel and its application as a superior anode material for Li-ion batteries

Abstract

We present a facile one-step synthesis of a three-dimensional macroscopic SnO₂–graphene aerogel. The as-prepared aerogel can be used as a superior anode material with a high reversible capacity and excellent cycling performance for Li-ion batteries, which may be primarily ascribed to the specific structure of the aerogel.
