Abstract: Iron nanoparticles that are useful for constructing electrodes for lithium ion batteries and a method of making said particles is disclosed herein. The nanoparticles may include magnetite. The electrode may be constructed by centrifuging the nanoparticles to a current collector, such as a disc of copper, without the use of an extrinsic binder. The solvothermal method of making nanoparticles decreases the time of the procedure from about 24 hours to about 75 minutes. The method of making electrode decreases the complexity and number of steps compared to the conventional procedure to prepare an electrode, and eliminates the use of additives (binder and current enhancer) and toxic NMP solvents in the electrode preparation process.

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.

Abstract: A device, e.g., a current collector and/or a lithium-ion or lithium-metal battery, is disclosed. The device includes a metallic substrate and a plurality of nanorod arrays arranged on the substrate. The plurality of nanorod arrays are porous metallic nanostructures and appear black in color. The plurality of nanorod arrays comprise titanium according to an example. The metallic substrate comprises a metal foil according to an example.
