Thispaper reports SPTCDA cathode for green and sustainablealuminum organic battery. Aluminumbatteries with aluminum as the anode and organic materialsas the cathode have continuously drawn considerable attention becauseof their high theoretical energy density, natural abundance, and environmentallybenign nature. Herein, we have done an elaborate design work on thebasis of & pi;-& pi; conjugated organic molecule PTCDAby a molecular engineering strategy. Introducing a sulfur atom toreplace the H atom in the aromatic ring of the PTCDA molecule to formSPTCDA (sulfurized PTCDA) with p-& pi; conjuga...
