Abstract Magnesium-ion batteries (MIB’s) can be an attractive alternative for grid-scale energy storage due to the abundance of Mg resources. Mg-ion battery has attracted much attention in the past two decades due to its high theoretical volumetric capacity (3833mAh/cm3) compared to lithium-ion battery [850mAh/cm3 (Graphite anode)]. Magnesium possesses two valence electrons and has a low standard reduction potential (-2.37 V vs. SHE). Until now only inorganic materials have been reported as anodes in Mg-ion batteries compatible only with Grignard type electrolytes. The dendrite free nature of Mg is amenable for assembling high voltage and high energy density batteries with suitable cathode materials, but the passivating behaviors of the Mg in carbonate type electrolytes make it irreversible. Organic electrode materials could be highly promising alternatives for inorganic counter-part. The organic materials are structure contrivable and environmentally benign achieving high gravimetric energy density and cycling stability in battery applications. In this work, magnesium perylene-3,4,9,10-tetracarboxylate (Mg2-PTC) was synthesized starting from perylene-3,4,9,10-tetracarboxylic acid-dianhydride (PTCDA). The Mg2PTC was characterized by XRD and other techniques to confirm the target molecule structure. Further, the electro-activity of Mg2-PTC was tested in carbonate type electrolyte by several electrochemical methods. Detailed electrochemical and spectroscopic investigations of the Mg2-PTC are underway.
