Biomass derived hierarchically porous carbon inherent structure as an effective metal free cathode for Li‐O2/air battery

Abstract A hierarchical porous carbon framework derived from betel‐nut is synthesized and employed as a bifunctional cathode in a Li‐O2/air battery. The prepared betel nut derived activated porous carbon (BNAPC) material exhibits an ordered and merged tube‐like porous morphology and a high specific...
