▎ 摘  要

NOVELTY - NaCl-rGO composite comprises rGO refers to reduced graphene oxide, and sodium chloride nanoparticles are located on the rGO. USE - NaCl-rGO composite for a positive electrode active material of a sodium secondary battery (all claimed), for use in electric vehicles and energy storage systems, a new secondary battery,such as mobile phones, camcorders, notebook PCs, electric vehicles, and research and development efforts on electrochemical devices are bearing fruit gradually. ADVANTAGE - The composite has exhibited high stability, high capacity, and long life while being inexpensive, has excellent competitiveness in terms of material availability and manufacturing cost, and a high-capacity battery can be prepared with a simple structure as compared to the lithium-ion battery, has provided a positive electrode active material with excellent reversibility and charge-discharge capacity through a simple process, has exhibited superior electrochemical properties with high capacity because the small NaCl particles are dispersed uniformly and are economically favorable because the preparation process is simple. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a positive electrode active material for a sodium secondary battery, which comprises the NaCl-rGO composite; and 2. a device, which comprises the sodium secondary battery, where the device is selected from an energy storage device, a transportation device, and a communication device.
