The present development is a process for the preparation of nanowire synthesis, coatings and uses thereof. Lithium titanate (LTO) nanowires are synthesized using a continuous hydrocarbon/plasma flame process technology combined with the dry impregnation method. The resulting LTO nanowires can be used as electro active anode materials for lithium ion batteries. The coating parameters, such as thickness, porosity of the film, packing density, and viscosity are controlled using the length of the nanowires, calendaring pressure, and slurry composition.

Provided is an improved method for forming lithium ion cathode materials specifically for use in a battery. The method comprises forming a first solution comprising a digestible feedstock of a first metal suitable for formation of a cathode oxide precursor and a multi-carboxylic acid. The digestible feedstock is digested to form a first metal salt in solution wherein the first metal salt precipitates as a salt of deprotonated multi-carboxylic acid thereby forming an oxide precursor. The oxide precursor is heated to form the lithium ion cathode material.

Embodiments disclosed herein relate to using cobalt (Co) to fine tune the magnetic properties, such as permeability and magnetic loss, of nickel-zinc ferrites to improve the material performance in electronic applications. The method comprises replacing nickel (Ni) with sufficient Co.sup.+2 such that the relaxation peak associated with the Co.sup.+2 substitution and the relaxation peak associated with the nickel to zinc (Ni/Zn) ratio are into near coincidence. When the relaxation peaks overlap, the material permeability can be substantially maximized and magnetic loss substantially minimized. The resulting materials are useful and provide superior performance particularly for devices operating at the 13.56 MHz ISM band.
