A positive electrode active material for a nonaqueous electrolyte battery. The positive electrode active material has been manufactured through a mixing step and a heating step. In the mixing step, a mixture is produced by mixing niobium pentoxide (NbO) with lithium hydroxide (LiOH) at a molar ratio of 1:1. In the heating step, the mixture is heated in an atmosphere of air at substantially 800&#xb0; C. The positive electrode active material having been produced through the mixing process and the heating process causes the plateau potential in a discharge to be approximately 1.0 [V] for lithium. And the nonaqueous electrolyte battery using the positive electrode active material can operate at a voltage of approximately 1.0 [V].

Active material containing niobium compound for use in nonaqueous electrolyte battery and nonaqueous electrolyte battery with positive electrode containing the active material

A batteryA with leads has a low-profile external casing actingas one of a pair of electrode terminals and a closure plateacting as the other of the electrode terminals. The closure platehermetically seals an opening of the external casingvia an insulating gasket. A pair of lead platesandare each welded to a different one of the electrode terminalsand. One of the lead platesandis secured to a circuit board X. The lead platethat is secured to the circuit board has a net-like structure.

Battery with leads

A lead plate-attached coin-type battery is constituted from a combination of a coin-type battery and a positive lead plate. In the coin-type battery, a negative cap seals the aperture of a positive outer can. In a lateral view, the positive lead plate is crank-shaped, and one end thereof is attached to the outer surface of the positive outer can of the coin-type battery. A lead plate is not attached to the negative cap. One or more projections that project in the Z axis direction are provided on the negative cap. In the lead plate-attached coin-type battery, the positive lead plate and negative cap have been attached to respective conductive lands on a circuit board by a solder reflow method.
