Abstract

Abstract : A 3D graphitic foam vertically aligned graphitic structure and a low density of defects is derived through chloroaluminate anion intercalation of graphite followed by thermal expansion and electrochemical hydrogen evolution. Such aligned graphitic structure affords excellent Al‐ion battery characteristics with a discharge capacity of ≈60 mA h g −1 under a high charge and discharge current density of 12 000 mA g −1 over ≈4000 cycles.
