A method for forming lithium metal oxides comprised of Ni, Mn and Co useful for making lithium ion batteries comprises providing precursor particulates of Ni and Co that are of a particular size that allows the formation of improved lithium metal oxides. The method allows the formation of lithium metal oxides having improved safety while retaining good capacity and rate capability. In particular, the method allows for the formation of lithium metal oxide where the primary particle surface Mn/Ni ratio is greater than the bulk Mn/Ni. Likewise the method allows the formation of lithium metal oxides with secondary particles having much higher densities allowing for higher cathode densities and battery capacities while retaining good capacity and rate performance.

Lithium metal oxide cathode materials and method to make them

A polymer composite comprising quantum dots; said polymer composite comprising: (a) quantum dots; (b) polymerized units of a first compound having at least one readily polymerizable vinyl group, a molecular weight from 300 to 20,000 and at least one continuous acyclic hydrocarbyl chain of at least five carbon atoms; and (c) polymerized units of a second compound having at least one readily polymerizable vinyl group and a molecular weight from 100 to 750; wherein a readily polymerizable vinyl group is part of a (meth)acrylate ester group or is attached directly to an aromatic ring, and the molecular weight of the first compound minus the molecular weight of the second compound is at least 100.

Polymer composite containing quantum dots

Particulate LMFP cathode materials having high manganese contents and small amounts of dopant metals are disclosed. These cathode materials are made by milling a mixture of precursor materials in a wet or dry milling process. Preferably, off-stoichiometric amounts of starting materials are used to make the cathode materials. Unlike other high manganese LMFP materials, these cathode materials provide high specific capacities, very good cycle life and high energies even at high discharge rates.

LMFP cathode materials with improved electrochemical performance

An improved method of making a cathode for use in a lithium ion battery is comprised of mixing a lithium metal oxide and lithium metal phosphate in a solvent, where both of these are comprised of primary particles that have been agglomerated into secondary particles of particular size and mixing is insufficient to break up the particles of the lithium metal phosphate, coating the mixture of step (A) on to a metal foil and removing the solvent to form the cathode. The lithium metal oxide is also desirably not broken either. The cathode may be one that has lithium metal oxide and a particular lithium metal phosphate wherein the majority of the metal is Mn.

A process for creating plasma polymerized deposition on a substrate by a corona discharge is described. The corona discharge is created between an electrode and a counterelectrode supporting a substrate. A mixture of a balance gas and a working gas is flowed rapidly through the electrode, plasma polymerized by corona discharge, and deposited onto the substrate as an optically clear coating or to create surface modification. The process, which is preferably carried out at or near atmospheric pressure, can be designed to create an optically clear powder-free or virtually powder free deposit of polymerized plasma that provides a substrate with properties such as surface modification, chemical resistance, and barrier to gases.

An electrode is provided which can improve the efficiency and quality of plasma-generated coatings in a plasma enhanced chemical vapor deposition coating device.
