20090197164 | PLATED STEEL PLATE FOR CELL CAN, BATTERY, ALKALINE DRY BATTERY - The invention provides a plated steel plate for a cell can in which stable and good electrical contact can be provided on an outer surface of the cell can, and the evolution of gas within a battery can be suppressed by reducing damage to a plated surface of the steel plate when the cell can is formed by drawing press. In this manner, it is possible to provide a battery and an alkaline dry battery that can realize stable electrical contact with devices and reduce the evolution of gas. In a plated steel plate | 08-06-2009 |
20090269661 | Battery Can and Method for Manufacturing the Same - A battery can of the present invention ensures a stable and favorable contact with an electrode and thus makes it possible to obtain a highly reliable battery excellent in high rate discharge characteristics. The battery can having an opening, including a cylindrical side portion and a bottom portion, of the present invention is formed from a steel plate. The steel plate has an Ni—Fe alloy layer on the inner face side of the battery can. The Ni—Fe alloy layer has an oxide layer containing iron and having a thickness of 10 to 50 nm on the inner face side of the battery can. | 10-29-2009 |
20100068618 | METHOD FOR PRODUCING ANODE CAN FOR BATTERY AND MANGANESE DRY BATTERY USING SUCH ANODE CAN FOR BATTERY - A manganese dry battery made from a virtually lead additive-free but highly reliable and practical anode zinc can that has improved process-ability and corrosion resistance. | 03-18-2010 |
20110206983 | ALKALINE BATTERY - An alkaline battery including a positive electrode of a hollow cylindrical shape disposed in contact with an inner surface of a bottomed cylindrical battery case, a gelled negative electrode, a separator, and an alkaline electrolyte. The separator includes a cylindrical separator disposed in contact with the inner side surface of the positive electrode, and a bottom separator covering an opening of the cylindrical separator in the bottom side of the battery case. The bottom of the battery case includes: an annular base portion for supporting the positive electrode; an annular intermediate portion provided inwardly of the base portion, for supporting the bottom separator; and a terminal portion protruding outwardly from the intermediate portion. The intermediate portion has an inclined surface on the inner bottom surface of the battery case, the inclined surface being inclined downwardly from the base portion toward the terminal portion. | 08-25-2011 |

20140295254 | MERCURY-FREE LEAD-FREE BUTTON BATTERY - A mercury-free lead-free button battery includes a negative cap, a cathode material, a gasket ring, a positive can, an anode material, and a diaphragm. The positive can and the negative cap are combined. The gasket ring is clamped between the positive can and the negative cap for separating the positive can from the negative cap. The cathode material is arranged on the bottom of the positive can. The diaphragm is arranged on the cathode material. The anode material is arranged between the negative cap and the diaphragm. A partition unit is arranged between the negative cap and the anode material for separating the anode material from the negative cap and conductively connecting the anode material and the negative cap. The partition unit ensures disconnection between the anode material and the negative cap and therefore safety of the battery by preventing expansion, weeping and even that would otherwise happen. | 10-02-2014 |
