Sb Nanoparticles Decorated with rGO as a New Anode Material in Aqueous Chloride Ion Battery

Abstract

An aqueous chloride ion battery (CIB) is an emerging technology for electrochemical energy storage as well as battery desalination systems. However, the instability and decomposition of electrode materials in an aqueous medium is a major issue in CIBs. Herein, by one-step, we synthesized the fine antimony nanoparticles with the size of ~20 nm on reduced graphene oxide (Sb@rGO) sheet using the hydrothermal route with the facile and cost-effective processes. It is proposed as a new anode material and coupled with AgCl cathode in an aqueous CIB. The specific capacity is maintained constantly with 51.6 mAh g-1 at a current density of 400 mA g-1 even after 200 cycles. In addition, the characterizations such as the electrochemistry, X-rays diffraction patterns etc. were conducted to confirm the reaction mechanism. The chloride ion capture material developed in this research work will be significant for the CIB as energy storage or battery desalination.
