摘要： An all-solid-state secondary battery includes a first electrode body having a first current collector and a first electrode layer, a second electrode body having a second current collector and a second electrode layer, and a solid-electrolyte layer disposed between the electrode layers. On the edge of the first current collector, a first insulating member is provided via a first bonding layer. On the edge of the second current collector, a second insulating member is provided via a second bonding layer. The side end face of the solid-electrolyte layer is disposed outside at least one of the side end faces of the first electrode layer and the second electrode layer. The bonding layers are separated from the respective inner side ends of the insulating members such that each of the current collectors has a deformable distortion buffering area.

摘要： A method for manufacturing an all-solid state secondary battery including a plurality of provisional battery bodies, the method including: forming each of the plurality of provisional battery bodies by pressing a positive-electrode mixture, a solid electrolyte, and a negative-electrode mixture that are stacked between a pair of electrode current collectors and pressure-molding the stacked provisional battery bodies with the electrode current collectors facing each other. The electrode current collectors facing each other have rough surfaces.

摘要： An electrostatic screen printer includes: an electrically conductive screen arranged in non-contact with a printing medium; sponges for rubbing a powder into the screen; and a direct current power source for applying a voltage to the printing medium and the powder, wherein the powder rubbed into the screen is adhered to the printing medium by electrostatic induction. The electrostatic screen printer includes a rotation mechanism for rotating the sponges, a parent revolution mechanism for parent revolution of the sponges, and a child revolution mechanism for child revolution of the sponges. The revolution speed ratio of the child revolution to the parent revolution may preferably be 4.0 or greater, a scraper is provided on the parent revolution mechanism so as to be interlocked with the revolution of the sponges, and the scraper is arranged so as to scrape the powder on the screen toward an axis of the parent revolution

摘要： The present invention provides an all-solid-state secondary battery and a method for producing the same, wherein it is possible to prevent the collapse of a laminate due to a shearing force occurring in the peripheral portion of the laminate when the laminate is pressed, and the occurrence of an internal short circuit can be prevented. The all-solid-state secondary battery includes a laminate and a plate-shaped insulating member both arranged between the positive electrode collector and the negative electrode collector. The laminate includes a positive electrode layer, a solid electrolyte layer, and a negative electrode layer. The plate-shaped insulating member is arranged around the laminate and contacted at least with the solid electrolyte layer to electrically insulate the positive electrode layer from the negative electrode layer. In the insulating member, a contact inner edge portion contacted with the laminate is thicker than a plate-shaped portion on the outer side.
