Abstract
- Lithium-rich disordered rocksalts such as Li<subscript>1.3</subscript>Nb<subscript>0.3</subscript>Mn<subscript>0.4</subscript>O<subscript>2</subscript> and Li<subscript>2</subscript>MnO<subscript>2</subscript>F are being investigated as high energy density cathodes for next generation Li-ion batteries. They can support the (de) lithiation of lithium ions over large compositional ranges while preserving the same overall structure. Here, we present a new Ni-rich oxyfluoride cathode, Li<subscript>2</subscript>NiO<subscript>2</subscript>F, with a disordered rocksalt structure. Li<subscript>2</subscript>NiO<subscript>2</subscript>F and can deliver a discharge capacity of 200 mAh g<superscript>-1</superscript> at an average voltage of 3.2 V. [ABSTRACT FROM AUTHOR]
