Bismuth Germanate (Bi4Ge3O12), a Promising High-Capacity Lithium-ion Battery Anode

Abstract

An unexplored promising lithiation-host anode material, Bi4Ge3O12, delivers a reversible specific discharge capacity of ~586 mAh g−1 at 200 mA g−1 after 500 cycles with a coulombic efficiency of ~99.8%. DFT calculations detected distorted [BiO6]9– octahedra, and band structure of BGO revealed an indirect gap of 3.50 eV. A plausible reaction mechanism of storing lithium is proposed.
