摘要： PROBLEM TO BE SOLVED: To provide a positive electrode material, a positive electrode, and a battery capable of outputting an amount of electricity near to the theoretical amount.
SOLUTION: The positive electrode 12 contains an Li-containing phosphate having olivine structure, and a compound having low redox potential capable of absorbing and releasing Li at the redox potential lower than that of the Li-containing phosphate, in a state capable of absorbing and releasing Li before charging and discharging, as positive electrode activators. A NASICON type compound like Li

3 (X fulfills 1.0≤X≤2.0 before charging/discharging) is recommendable as a compound having low redox potential. The capacity is improved by supplementing the capacity loss of the Li-containing phosphate by utilizing the compound having low redox potential at the area where the inside impedance of the Li-containing phosphate is high.

摘要： PROBLEM TO BE SOLVED: To provide a battery capable of improving battery properties such as a capacity and a cycle property by preventing a negative electrode from being exposed at a low voltage for a long while.
SOLUTION: A positive electrode 12 and a negative electrode 14 are arranged with an interposition of a separator 15. The positive electrode 12 includes a phosphate compound containing lithium and iron as a positive electrode active material. An excessive reduction of the negative electrode voltage is suppressed by lowering a charging voltage as at 3.3 V to 3.8 V and a utilization factor expressed as a positive electrode discharge capacity/negative electrode discharge capacity at 90% to 100%. A load on the negative electrode 14 is reduced by lowering the charging voltage and a resistance is reduced by lowering the utilization factor, so that an acceptance property of the negative electrode 14 is improved. It is preferable that there is a mutual action between the charging voltage and the utilization factor and an index K expressed by charging voltage
3 × utilization factor is maintained within a range from 37 to 47 not inclusive.

摘要： PROBLEM TO BE SOLVED: To provide a battery of which the initial defective ratio is improved and the battery characteristics such as battery capacity and load property can be improved, and its manufacturing method.
SOLUTION: The battery comprises a wound electrode body 20 in which a positive electrode 21 and a negative electrode 22 are laminated and wound through an electrolyte 23 that contains a polymer material and an insulating particle 23a. Since the width of the electrolyte 23 is larger than the positive electrode 21 and the negative electrode 22 by 0.5 mm or more and 4 mm or less, the positive electrode 21 and the negative electrode 22 are completely covered, thereby, short circuit is prevented. It is desirable that the content of the insulating particle 23a is 6 volume % or more and 15 volume % or less. It is desirable that the average distance between the electrodes is 15 μm or more and 50 μm or less, and the average particle size of the insulating particle 23a is made 0.5 μm or more and 5 μm or less. In the manufacture, after the electrolyte 23 is formed, it is pressurized while heating, thereby, the internal resistance of the electrolyte 23 is reduced and the insulating particle 23a is dispersed in the electrolyte 23 uniformly.

SOLUTION: In the battery, a disc-shaped positive electrode 12 housed in an outer sheath can 11 and a disc-shaped negative electrode 14 housed in an outer sheath cup 13 are laminated via a separator 15. The inside of the outer sheath can 11 and the outer sheath cup 13 are filled with an electrolytic solution 16 composed of a solvent in which lithium salt is dissolved. The electrolytic solution 16 also contains silver, of which the concentration is of a mass ratio of 10,000 ppm or less to the solvent, wherein at least part of the silver is deposited on the negative electrode 14 through an electrolytic process occurring upon charging the battery. As a result, the negative electrode 14 is not covered excessively with silver so that superior electrode reactions are secured.

摘要： PROBLEM TO BE SOLVED: To suppress winding looseness of a laminated electrode body at a winding center of a wound electrode body. SOLUTION: The wound electrode body is manufactured by using a five-layer structured laminated electrode body that is composed by laminating in the order of a positive electrode; a separator; a negative electrode; a separator; and a positive electrode so that a cathode active material layer and the negative electrode are opposite to each other via the separator, while using the positive electrode in which the cathode active material layer is provided on one face of a positive-electrode current collector. Winding is executed by providing a winding start at a position apart from one end of the laminated electrode body at a distance of more than 5% of an electrode length of the laminated electrode body. Consequently, it is possible to bendingly arrange the laminated electrode body so as to pass through the center axis of a space of a winding innermost periphery without exposing the end of the laminated electrode body at the winding center where a fixing member is hardly provided. The end of the laminated electrode body is exposed at the winding outermost periphery, and is fixed with a fixing member. It is more preferable that the laminated electrode body arranged at the winding innermost periphery is composed so as to have a nearly S-shaped cross-section. COPYRIGHT: (C)2008,JPO&INPIT
