A method for preparing high nickel lithiated metal oxides that includes selecting one or more nickel precursors; at least one non-corrosive lithium salt; and a plurality of metal oxide or hydroxide precursors. The metal precursors and lithium salts are mixed together to form a mixture comprising:LiNiMNOFa  (F-1)wherein x=1.0-1.1, 0.80≤y≤0.90, 0.03<z≤0.15, and 0≤a≤0.05; M is Co or Fe; and N is Al, Mn, Fe, Ca, Mg, Ti, Cr, Nb, Mo, W, B, or a mixture thereof provided N may be Fe when M is Co. The mixture is subjected to sintering (1st step) in air at ≥750° C. to form a powder. The powder is subjected to a 2sintering step in Oat ≤750° C. to form the high nickel lithiated metal oxides.

A method of manufacturing a three-dimensional electrochemical lithium battery includes forming a first electrode on an underlying layer comprising aerosolizing a first ink formulation comprising a slurry including nanoparticles or microparticles of a first active material and a binder, and depositing the slurry onto the underlying layer to form a first electrode layer. A permeable separator layer is formed on the first electrode by aerosolizing a polymer precursor solution, exposing the aerosolized polymer precursor solution to a first activating radiation source to form partially cured polymer spheres in the aerosolized stream, focusing and directing the aerosolized stream onto a substrate to form the permeable separator layer of the partially cured polymer spheres, and exposing the partially cured polymer spheres on the substrate to a second activating radiation source to fully cure the partially cured polymer spheres. A second electrode is formed on the permeable separator layer by aerosolizing a second ink formulation comprising a slurry including nanoparticles or microparticles of a second active material and a binder, and depositing the slurry onto the permeable separator layer.

Negative electrode active material for energy storage devices and method for making the same

At least one embodiment of the present invention provides preparation methods and compositions for nanoarchitectured multi-component materials based on carbon-coated iron-molybdenum mixed oxide as the electrode material for energy storage devices. A sol-gel process containing soluble organics is a preferred method. The soluble organics could become a carbon coating for the mixed oxide after thermal decomposition. The existence of the carbon coating provides the mixed oxide with an advantage in cycling stability over the corresponding carbon-free mixed oxide. For the carbon-coated mixed oxide, a stable cycling stability at high charge/discharge rate (3A/g) can be obtained with Mo/Fe molar ratios &#x2267;1/3. The cycling stability and rate capability could be tuned by incorporating a structural additive such as AlOand a conductive additive such as carbon nanotubes. The high rate performance of the multi-component material has been demonstrated in a full device with porous carbons as the positive electrode material.
