New choice of energy battery electrode materials in new energy vehicles: preparation of graphene aerogels by γ ray irradiation method

Abstract

Graphene aerogel are frequently employed as electrode materials for power batteries due to their high specific surface area and excellent properties. This paper presents a method for preparing graphene aerogel by radiolytic reduction in a water and isopropanol system. In this study, the authors used radiolytic reduction technology to reduce graphene oxide to graphene aerogel and investigated the effects of various factors in the water and isopropanol system on its preparation process and properties. The experimental results showed that the water and isopropanol system could effectively prepare graphene aerogel with a high specific surface area, and the isopropanol concentration and irradiation time in the isopropanol system had important effects on its properties. This preparation method has the advantages of simplicity, rapidity, and low cost, providing a new idea for the large-scale preparation of graphene aerogel.
