Provided are a method for manufacturing a vacuum insulation glass panel and a device for closing a sealing cap, the method and the device being for exhausting air between two glass panels and sealing the same. The method for manufacturing a vacuum insulation glass panel, according to the present invention, heats the glass solder applied on the sealing cap before being put into a vacuum chamber, and then presses, by the operation of the elevating device, the sealing cap put into the vacuum chamber so as to join the sealing cap around the exhaust hole. The holder having the sealing cap is mounted in the clamping unit, and then the clamping unit is clamped to the glass panel assembly, thereby enabling the exhaust hole to be accurately closed with the sealing cap.

A part of a glass layer 103 disposed along a region to be fused R is irradiated with a laser beam L1, so as to form the glass layer 103 with a laser-absorbing part 108a having a high laser absorptance. Then, while using the laser-absorbing part 108a as an irradiation initiation position, the region to be fused R is irradiated therealong with a laser beam L2, so as to melt the glass layer 103 and fix the glass layer 103 onto a glass member 104. Since the irradiation initiation position for the laser beam L2 has already become the laser-absorbing part 108a, a stable region where the melting of the glass layer 103 is stable can be formed immediately from the start point for initiating the irradiation with the second laser beam or nearby. The glass member 104 is fused to a glass member 105 through the glass layer 103 having such a stable region formed throughout the region to be fused R, so as to yield a glass fusing structure 101.

Certain example embodiments of this invention relate to edge sealing techniques for vacuum insulating glass (VIG) units. More particularly, certain example embodiments relate to techniques for providing localized heating to edge seals of units, and/or unitized ovens for accomplishing the same. In certain example embodiments, a unit is pre-heated to one or more intermediate temperatures, localized heating via at least one substantially two-dimensional array of heat sources is provided proximate to the peripheral edges of the unit so as to melt frits placed thereon, and cooled. In certain non-limiting implementations, the pre-heating and/or cooling may be provided in one or more steps. An oven for accomplishing the same may include multiple zones for performing the above-noted steps, each zone optionally including one or more chambers. Accordingly, in certain example embodiments, a temperature gradient proximate to the edges of the unit is created, thereby reducing the chances of breakage and/or at least some de-tempering of the substrates.

A standalone lithium ion-conductive solid electrolyte including a freestanding inorganic vitreous sheet of sulfide-based lithium ion conducting glass is capable of high performance in a lithium metal battery by providing a high degree of lithium ion conductivity while being highly resistant to the initiation and/or propagation of lithium dendrites. Such an electrolyte is also itself manufacturable, and readily adaptable for battery cell and cell component manufacture, in a cost-effective, scalable manner.

An electronic device may have a glass housing structures. The glass housing structures may be used to cover a display and other internal electronic device components. The glass housing structure may have multiple glass pieces that are joined using a glass fusing process. A peripheral glass member may be fused along the edge of a planar glass member to enhance the thickness of the edge. A rounded edge feature may be formed by machining the thickened edge. Raised fused glass features may surround openings in the planar glass member. Multiple planar glass members may be fused together to form a five-sided box in which electronic components may be mounted. Raised support structure ribs may be formed by fusing glass structures to a planar glass member. Opaque masking material and colored glass may be used to create portions of the glass housing structures that hide internal device components from view.
