Dilithium 2-aminoterephthalate as a negative electrode material for lithium-ion batteries

Abstract This work presents the synthesis and characterization of a novel organic Li-battery anode material: dilithium 2-aminoterephthalate (C 8 H 5 Li 2 NO 4 ). When investigated in Li half-cells, the resulting electrodes show stable capacities around ca. 180 mAh g − 1 and promising rate capabilities, with battery performance at 500 mA g − 1 and good capacity recovery, despite being an asymmetric compound. DFT calculations indicate a preferential lithiation on carboxylates close to the amino group.
