Key Points

To explore the electron and ion transport properties of SePAN within a holey-graphene aerogel framework for Na–Se batteries.
Seleniumized polyacrylonitrile synthesis
Fabrication of a 3D holey-graphene aerogel
Conductivity measurements to assess electron and ion transport
Significant enhancement in electron and ion transport rates
Reduced polyselenide dissolution observed
Improved performance metrics for Na–Se batteries under high-loading conditions

Abstract

Seleniumized polyacrylonitrile (SePAN) has emerged as a promising cathode for sodium–selenium (Na–Se) batteries due to its covalent C–Se bonding configuration that suppresses polyselenide dissolution. However, its practical application under high...
