A 3D porous Al foil coated with a uniform carbon layer (pAl/C) is prepared and used as the anode current collector in dual-ion battery (DIB). The pAl/C-graphite DIB demonstrates superior cycling stability high rate performance, achieving highly reversible capacity of 93 mAh g−1 after 1000 cycles at 2 C over voltage range 3.0–4.95 V. In addition, could achieve an energy density ≈204 Wh kg−1 power 3084 W kg−1. As service to our authors readers, this journal provides supporting information supplied by authors.
