Abstract: A method for producing an all-solid multilayer battery, and an all-solid multilayer battery. The all-solid multilayer battery may be produced by depositing, by electrophoresis without any binder, at least one anode layer, at least one electrolyte layer, and at least one cathode layer. The at least one electrolyte layer, and the at least one cathode layer are obtained from a colloidal suspension containing nanoparticles that are not agglomerated with each other to create clusters and remain isolated from each other. A layer of Ms bonding material is then deposited on a surface of the at least one electrolyte layer. Next, two layers from the at least one dense anode layer, the at least one dense electrolyte layer, and the at least one dense cathode layer, are stacked face-to-face to obtain the all-solid multilayer battery having an assembly of a plurality of elementary cells connected with one another in parallel.

Abstract: A hot-pressing tool mounted on a press and operable under a controlled atmosphere, a method for implementing such a hot-pressing tool, and a facility for manufacturing objects that includes such a hot-pressing tool. The tool includes a first tool portion having a first fastening device to fasten onto a first platen, a second tool portion having a second fastening device to fasten onto a second platen. The first fastening device and the second fastening device are mobile with respect to one another to define a pressing chamber having an inner volume which is heated via a heating device. The first fastening device and the second fastening device each respectively have a pressing member to exert a pressing force on opposite faces of an object to be pressed in the pressing chamber. The heating device is to heat via optical radiation that is concentrated on the object via a concentration device.
