Quantum computational (QC) study of Supercapacitors and Li-ion batteries

Supercapacitors and ion-lithium batteries are some of the most important electric storage devices due to their high specific Power density, high cycling life and high specific capacity. Therefore, the quantum computational study of the electrodic materials of this devices is also increasing. Despite the expectation the experimental results showed that graphene did not have significant capacity as a supercapacitor electrode, which was attributed to its hydrophobicity. In 2013 Peak et al showed that the major problem of graphene is its low quantum capacity which is the ability of the electrode to store electrical charge.
