Explosive effect-assisted synthesis of hierarchical porous carbon for high-performance aqueous Zn-ion hybrid supercapacitors with commercial level mass loading

•Explosive effect assists in regulation of the morphology, porosity, and surface chemistry to boost the ion accessibility and kinetics.•An ultrahigh reversible capacity (189.3 mAh g−1 at 0.1 A g−1) and excellent rate performance (96 mAh g−1 at 20 A g−1) are achieved.•The NPCN electrode with a commercial level mass loading (15 mg cm−2) could deliver an extremely high capacity of 170.1 mAh g−1 at 0.1 A g−1.•The universality of this synthesis is demonstrated by using various soft carbon precursor.
