Positive-electrode active material for nonaqueous electrolyte secondary battery and method for producing the same, and nonaqueous electrolyte secondary battery

The present invention provides a cathode active material for a nonaqueous electrolyte secondary battery with a high capacity, high stability and excellent output characteristics and a method for producing the same, and a nonaqueous electrolyte secondary battery using the cathode active material.
The cathode active material for a nonaqueous electrolyte secondary battery is represented by a general formula: LitNi1.x.y.zCoxAlyTizO2 wherein 0.98≦t≦1.10, 0<x≦0.30, 0.03≦y≦0.15, 0.001≦z≦0.03; and includes a hexagonal lithium-containing composite oxide with a layer structure of secondary particles having primary particles, in which a titanium-enriched layer is formed on a surface of the primary particles and/or a grain boundary between the primary particles. The titanium-enriched layer on the surface of the primary particles and/or a grain boundary between the primary particles serves as a lithium ion conductor, yielding smooth extraction and insertion of lithium ions. Accordingly, the secondary battery with a high capacity, high stability and excellent output characteristics can be produced when a positive electrode is formed with the lithium nickel composite oxide as a cathode active material.

Reel having an improved reciprocating mechanism

A reel comprises a drum assembly enclosed within a shell comprising upper and lower shell portions. The drum assembly is secured to the lower shell portion. The drum assembly comprises a motor-driven rotating drum rigidly secured between two discs, and a frame subassembly. The drum is adapted to received a linear material spooled thereon. A first of the discs has a spiral groove on an outer surface thereof. The spiral groove has a first end near the center of the first disc and a second end near an outer edge thereof. The second end is tapered to lesser depth. The frame subassembly comprises side plates enclosing the drum and discs. A first side plate has a track assembly attached to its inner surface, and a translating plate adapted to translate horizontally within the track assembly. The translating plate has a horizontal pin at each of its ends, which pins are adapted to be received within the spiral groove of the first disc. As the drum and discs rotate, the horizontal pins alternatingly engage the spiral groove, causing the translating plate to translate linearly within the track assembly. The translating plate is connected to the upper shell portion, causing the upper shell portion to reciprocatingly rotate about a vertical axis with respect to the lower shell portion and drum assembly. A guide aperture is provided in the upper shell portion, through which linear material is drawn onto the rotating drum. Advantageously, the aperture translates through an arc in front of the drum, so that the linear material is distributed across the drum surface as it is wound.

Very large dataset representation system and method

A system and method for representing a very large dataset that enables a plan manager to define, based upon an organization modelling object, a delegation modelling object for a very large dataset. A very large dataset delegation of multiple subplans is created whose subplans can then be individually filtered for specific size restrictions. This enables a plan manager to filter the definition of each subplan prior to the execution of the delegation modelling object, precluding any need for higher-level subplans to contain all the data contained in their subordinate subplans. This allows subplans to contain increased levels of detail not included in their superior subplans, detail that will instead only be summarized in higher-level subplans. A subsequent consolidation process will then extract data not found at higher levels from each delegated subplan, and return that data to its original dataset.
