A novel storage design for ultrahigh-cell-voltage Al-ion batteries utilizing cation–π interactions†
Abstract
We propose a novel storage design for ultrahigh-cell-voltage Al-ion battery by utilizing cation–π interactions by means of density functional theory (DFT) computations. The ultrahigh cell voltage can reach up to ∼12 V, which is about 6 times that of the cell voltages of current Al-ion batteries; further, the heat loss can be considerably reduced.
