Abstract
A lithium-ion battery may include a lithium-free cathode, a lithiated anode, and a separator/electrolyte between the lithium-free cathode and the lithiated anode. The lithium-free cathode may include FeOF and MnO2. The FeOF may be in the form of nanorods, and the MnO2 may be in the form of monolayer nanosheets. The FeOF nanorods may be sandwiched or wrapped by the monolayer MnO2 nanosheets.
