Methods and systems are provided for a cathode material for lithium ion batteries. In one example, the cathode material may include a lithium mixed metal oxide core and a surface coating surrounding the core. Optionally, a passivating layer may continuously surround the surface coating. In some examples, the surface coating or surface layer may include a sacrificial lithium source, a lithium-based active cathode catalyst, or a combination thereof. In other examples, methods are provided for manufacturing the cathode material for use in a lithium ion battery.

Cathode with pre-lithiation coating and methods for preparation and use

A coated cathode material for lithium-ion batteries is disclosed. Methods and systems are further provided for applying a coating to an active cathode material for use in a lithium-ion battery. In one example, the coated cathode material may include a high-nickel content active cathode material, such as lithium nickel manganese cobalt oxide or lithium nickel aluminum cobalt oxide, coated with a coating including one or more high energy density active materials, such as lithium vanadium fluorophosphate and/or a lithium iron manganese phosphate compound. In some examples, the high-nickel content active cathode material may include greater than or equal to 60% nickel content.

Method and systems for coated cathode materials and use of coated cathode materials

Systems and methods are provided for an electrode for a lithium-ion battery cell. In one example, the electrode may include a current collector having two opposing sides, at least one of the two opposing sides being configured with a first coating layer disposed on the current collector at a first loading, where the first coating layer may include a first binder in a first weight ratio, and a second coating layer disposed on the first coating layer at a second loading, where the second coating layer may include a second binder in a second weight ratio, wherein the first weight ratio may be greater than the second weight ratio, and a ratio of the first loading to the second loading may be less than 1:2. In this way, direct current internal resistance of the lithium-ion battery cell may be decreased while maintaining or increasing adhesion within the electrode.

Multi-layered coated electrode for lithium-ion battery

Materials and methods for coating an electrochemically active electrode material for use in a lithium-ion battery are provided. In one example, an electrochemically active electrode material comprises: a polymer coating applied directly to an exterior surface of the electrochemically active electrode material; a metal plating catalyst adhered to the continuous polymer; and a continuous metal coating that completely covers the metal catalyst and continuous polymer coating. The electrochemically active electrode material may comprise a powder comprising one or more secondary particles, and the polymer and metal coatings may be applied to exterior surfaces of these secondary particles.

Process for metallization of electrochemically active powders

A silicon anode comprising a hybrid binder at a blending ratio of 10-90 wt. % for use in a Li-ion battery is provided. The combination of a hybrid binder in the Si anode for use in a rechargeable Li-ion cell shows the unexpected result of extending the cycle life and a balancing effect between adhesion strength and first cycle efficiency.

High capacity anode electrodes with mixed binders for energy storage devices

A polishing slurry can include zirconia particles. The polishing slurry can be used to polish conductive and insulating materials, and is particularly well suited for polishing oxide materials as well as metals. The characteristics of the zirconia particles can affect the polishing of workpieces. By selecting the proper characteristics, the polishing slurry can have a good material removal rate while still providing an acceptable surface finish. The zirconia particles can be used as a replacement for, or in conjunction with, ceria or other abrasive particles. The content of zirconia particles in the polishing slurry may be less than a comparable polishing slurry having silica or alumina particles.

Polishing slurry including zirconia particles and a method of using the polishing slurry

A method for chemical mechanical polishing of a substrate includes polishing the substrate at a stock removal rate of greater than about 2.5 &#x212b;/min to achieve a Ra of not greater than about 5.0 &#x212b;. The substrate can be a III-V substrate or a SiC substrate. The polishing utilizes a chemical mechanical polishing slurry comprising ultra-dispersed diamonds and at least 80 wt % water.

Chemical mechanical planarization using nanodiamond

An abrasive particulate material is disclosed that includes alumina particles. The alumina particles include a transition alumina and at least 5.0 wt % of an amorphous phase. The transition alumina particles also have a density not greater than about 3.20 g/cm.

Abrasive particulate material, and method of planarizing a workpiece using the abrasive particulate material

A particulate material comprising cerium oxide particles having a secondary particle size distribution in a range of 80 nm to 199 nm and a density of at least 6.6 g/cm.
