15339 results about "Manganese" patented technology

Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a transition metal with important industrial alloy uses, particularly in stainless steels.

Materials for positive electrodes of lithium ion batteries and their methods of fabrication

This invention discloses materials for positive electrodes of secondary batteries and their methods of fabrication. Said materials comprise of granules of an active material for positive electrodes coated with an oxide layer. The active material is one or more of the following: oxides of lithium cobalt, oxides of lithium nickel cobalt, oxides of lithium nickel cobalt manganese, oxides of lithium manganese, LiCoO2, LiNi1-xCoxO2, LiNi1/3Co1/3Mn1/3O2, and LiMn2O4. The non-oxygen component in the oxide layer is one or more of the following: aluminum, magnesium, zinc, calcium, barium, strontium, lanthanum, cerium, vanadium, titanium, tin, silicon, boron, Al, Mg, Zn, Ca, Ba, Sr, La, Ce, V, Ti, Sn, Si, and B. Said non-oxygen component of the granules is between 0.01 wt. % to 10 wt. % of said granules of active material. The methods of fabrication for said materials includes the steps of mixing an additive and an active material for positive electrodes uniformly in water or solvent, evaporating said solvent or water, and heat treating the remaining mixture at 300° C. to 900° C. for between 1 hour to 20 hours. The additive is a compound of one or more of the following elements: aluminum, magnesium, zinc, calcium, barium, strontium, lanthanum, cerium, vanadium, titanium, tin, silicon, boron, Al, Mg, Zn, Ca, Ba, Sr, La, Ce, V, Ti, Sn, Si, and B where the element is between 0.01 wt. % to 10 wt. % of said active material. Using the materials of positive electrodes disclosed above or materials for positive electrodes fabricated in the methods disclosed above in batteries produces batteries with excellent cycling and high temperature properties.

Gradient cathode material for lithium rechargeable batteries

A composition suitable for use as a cathode material of a lithium battery includes a core material having an empirical formula LixM′zNi1−yM″yO2. “x” is equal to or greater than about 0.1 and equal to or less than about 1.3. “y” is greater than about 0.0 and equal to or less than about 0.5. “z” is greater than about 0.0 and equal to or less than about 0.2. M′ is at least one member of the group consisting of sodium, potassium, nickel, calcium, magnesium and strontium. M″ is at least one member of the group consisting of cobalt, iron, manganese, chromium, vanadium, titanium, magnesium, silicon, boron, aluminum and gallium. A coating on the core has a greater ratio of cobalt to nickel than the core. The coating and, optionally, the core can be a material having an empirical formula Lix1Ax2Ni1−y1−z1Coy1Bz1Oa. “x1” is greater than about 0.1 a equal to or less than about 1.3. “x2,”“y1” and “z1” each is greater than about 0.0 and equal to or less than about 0.2. “a” is greater than 1.5 and less than about 2.1. “A” is at least one element selected from the group consisting of barium, magnesium, calcium and strontium. “B” is at least one element selected from the group consisting of boron, aluminum, gallium, manganese, titanium, vanadium and zirconium.

Nutrition bar

A nutrition bar comprising about 10% wt or more of soy and/or rice protein, at least one transition metal or transition metal compound, and about 2% wt or more of a humectant, and wherein the at least one transition metal or transition metal compound is in a substantially water insoluble form at 20° C. or the nutrition bar has an Aw of 0.45 or less or about 1% wt or more of the soy and/or rice protein is in the form of nuggets and the humectant is selected from polyols. The bars have elevated levels of soy and/or rice protein, yet do not suffer unacceptable from a deterioration in taste or other organoleptic properties over time. In other aspects, a nutrition bar or other food which incorporates pro-oxidants and/or polyunsaturated fatty acids or their sources in encapsulated form, especially as microcapsules. The pro-oxidants may be metal salts such as copper, manganese, iron and/or zinc salts. Sources of omega-3 fatty acids include fish oil. Processes for preparing the polyunsaturated fatty acid capsules are also disclosed. The polyunsaturated fatty acid capsules/microcapsules are prepared by forming an emulsion of the unsaturated fatty acid with a carrier, spray drying the emulsion to form a powder and encapsulating powder, especially with a fluid bed. The invention is especially useful for encapsulating polyunsaturated fatty acids, or oil sources thereof, most preferably omega-3 and omega-6 fatty acids, such as arachidonic acid, docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), lineoleic acid, linolenic acid (alpha linolenic acid), and gamma-linolenic acids, fish oil, and oil sources of C18:2 and C18:3 fatty acids such as canola oil, soybean oil or blends thereof.
