Ionic Liquid‐Assisted Preparation of Sb2S3/Reduced Graphene Oxide Nanocomposite for Sodium‐Ion Batteries

Ionic Liquid‐Assisted Preparation of Sb2S3/Reduced Graphene Oxide Nanocomposite for... Sodium‐ion batteries are regarded as a promising alternative to lithium ion batteries.

Here, a stibnite/reduced graphene oxide nanocomposite is reported, fabricated by an ionic liquid‐assisted hydrothermal method, for sodium‐ion batteries. The obtained nanocomposite gives a high capacity of 687.7 mA h g−1 at 50 mA g−1 and an impressive rate performance.

Abstract

Sodium‐ion batteries are regarded as a promising alternative to lithium ion batteries. However, their application is restricted by the low capacity and poor rate performance of existing anodes. Here, a stibnite/reduced graphene oxide nanocomposite is reported, fabricated by an ionic liquid‐assisted hydrothermal method, for sodium‐ion batteries. The obtained nanocomposite gives a high capacity of 687.7 mA h g−1 at 50 mA g−1 and an impressive rate performance. The promising electrochemical properties can be attributed to the uniformly distribution of Sb2S3 on reduced graphene oxide layers and the close contact between the two composites, which can be ensured by the addition of ionic liquid during the synthesizing process. This facile method shall pave the way for the production of other graphene‐based nanocomposite for sodium ion batteries and other energy storage systems.
