Anode active material and battery

An anode active material with a high capacity capable of providing superior cycle characteristics and a battery using it are provided. An anode contains an anode active material capable of reacting with lithium. The anode active material contains at least tin, iron, and carbon as an element. The carbon content is from 11.9 wt % to 29.7 wt %, and the iron ratio to the total of tin and iron is from 26.4 wt % to 48.5 wt %. Thereby, while a high capacity is maintained, the cycle characteristics are improved.

Anode, battery, and method of manufacturing same

A battery capable of improving cycle characteristics is provided. An anode active material layer is formed by forming a precursor layer containing active material particles containing Si and Li as an element, and then heating the resultant. Thereby, the active material particles are bound to each other by sintering or fusing, and united three-dimensionally. Since Li is contained therein, the active material particles can be sufficiently sintered even if the heating temperature is low, 600 deg C.

InactiveUS6912064B1Accurately correctAccurately correct environmental variation and aged variationImage enhancementDigitally marking record carriersImage sensorBit numbering
In order to accurately correct environmental variation and aged variation of gamma characteristics, RGB tone data are color-converted to be formed as CMYK tone data, then a tone correction for improving gamma characteristics is performed on the CMYK tone data. The CMYK tone data after the tone correction are subjected to half-toning to be converted into half-tone data. On the basis of the half-tone data, an image is printed by an electrophotography process. A test image is printed at a predetermined timing. A sensor reads the test image. On the basis of a signal of the sensor, a correction table for the tone correction is calculated by correction table calculation. In the tone correction, 8-bit input tone data are converted into 10-bit corrected tone data. Since the tone correction is performed on CMYK data in place of RGB data and the bit number of tone data is extended from 8 bits to 10 bits by the tone correction, the accuracy of improvement of gamma characteristics is enhanced.
