Bismuth oxyiodide nanosheets: a novel high-energy anode material for lithium-ion batteries†
Abstract
BiOI nanosheets are easily synthesized by direct thermal treatment of commercial BiI3 powder, serving as a novel anode material for lithium-ion batteries. A high volumetric capacity of ∼5678 mA h cm−3 was achieved. This work demonstrates that the BiOI nanosheets hold great promise as high-energy anode material for lithium-ion batteries.
