The laser beam operates at a frequency of more than 67 Hz, and the spot of the laser beam is sequentially moved to different drilling positions for each pulse. After all of many drilling positions in the range of a scan vision are irradiated with the laser beam pulse by pulse, or after the elapse of a time of 15 ms or more from irradiation of the first drilling position, the laser spot is returned to the first drilling position. The spot is sequentially moved once again, and the movement is repeated several times.

Abstract: A method of the present invention is a method for processing a multilayer material, in which one or more conductor layers and insulating layers are layered, with a laser beam. The method includes the step of irradiating the conductor layer with a first laser beam to form a hole at a processing point in the conductor layer, and the step of irradiating the hole with a second laser beam to process the insulating layer, layered on the conductor layer. The second laser beam has a smaller beam diameter at the processing point than the first laser beam.

Abstract: In case of a conventional battery having a laminated sheet material as a battery case for storing a battery body, the metal foil on the laminated sheet does not contact to either a positive electrode or a negative electrode and electric potential is unstable. Therefore, there was a problem that it was impossible to obtain electrical shielding effect. In order to maintain the function of the sealed part in the battery case, an extended part extended from the sealed part is disposed at a position where it overlaps with the positive electrode lead or the negative electrode lead, and by jointing the lead and the extended part with the conductive material piercing therethrough, the metal foil on the laminated sheet material of the battery case is electrically connected to the lead to maintain the electric potential of the battery case to the electric potential of the positive electrode or the negative electrode.

Abstract: A battery body, which is composed of a laminated body obtained by laminating a cathode and an anode via a separator or a wound body obtained by winding them in a laminated structure and a plurality of leads connected to the cathode and the anode, is contained in a flexible package, and after an electrolyte solution is injected thereinto, an opening of the package is sealed at pressure which is lower than atmospheric pressure and is reduced to not less than vapor pressure of the electrolyte solution so that a thin battery is fabricated. A rise in pressure in the battery due to generation of gas in the battery and volume expansion of the gas can be restrained when the battery is maintained at high temperature.

Abstract: A battery package including laminate sheets adhered each other along their peripheral to form a container portion for receiving an electrode assembly and a seal portion. The seal portion surrounds the container portion and protrudes outwardly from side faces of the container portion. The seal portion has enough width to maintain the container portion free from moisture for long periods of time. The laminate sheets include a heat-adhesive polymer layer and a metal layer which stops moisture and provides a shape-maintaining ability to the laminar sheets. The seal portion is folded or curled to reduce a projection area of the battery package.

Abstract: Burst pressure P of an insulating layer positioned immediately on a fuse layer is defined by using planar width W of fuse layer and thickness t of insulating layer. The value of the planar width W of fuse layer and the value of the thickness t of insulating layer are set such that the value of burst pressure P is at most about 1000 kg/cm.sup.2. The value of the thickness t and the value of the planar width W are set such that the value t/W is at least 0.45 and at most 0.91. Consequently, stable fuse blowing becomes possible while reducing manufacturing cost.
