| Abstract Scope |
The enhancement of ion transport in electrodes is critical to the performance of the organic electrochemical systems as they suffer from poor ionic conductivity. In organic flow batteries, convective flux of electrolytes by pressure gradient is a main driving force for the ion transport in addition to electric field, and thus, the improvement of the convective ion transport is needed. In our research, for the development of graphene electrodes with effective ion transport, we studied the synthesis of directionally porous graphene aerogel (D-GA) and the ion transport in graphene nanochannels. Since D-GA is synthesized using freeze casting, water-ice phase change and graphene structuring processes were computationally investigated via molecular dynamics and finite volume method. Also, the coupling of the pressure-driven and electric field driven ion transport was examined using molecular dynamics of graphene nanochannels. Recent progress from our multiscale computational research for the graphene electrode development will be presented. |
