20100310758 | METHOD FOR PRODUCING AT LEAST ONE MICROCOMPONENT WITH A SINGLE MASK - The microcomponent, for example a microbattery, comprising a stack with at least two superposed layers on a substrate, is made using a single steel mask able to expand under the effect of temperature. The mask comprises at least one off-centered opening. The mask being at a first temperature, a first layer is deposited through the opening of the mask. The mask being at a second temperature, higher than the first temperature, a second layer is deposited through the opening of the mask. Finally, the mask being at a third temperature, higher than the second temperature, a third layer is deposited through the opening of the mask. | 12-09-2010 |
20100326814 | METHOD FOR ELIMINATING METALLIC LITHIUM - The method for eliminating metallic lithium on a support comprises a plasma application step. The plasma is formed from a carbon source and an oxygen source with a power comprised between 50 and 400 W. It transforms the metallic lithium into lithium carbonate. The method then comprises a dissolution step of the lithium carbonate in an aqueous solution. | 12-30-2010 |

20120321938 | MICROBATTERY AND METHOD FOR MANUFACTURING SAME - The invention relates to a microbattery that comprises a stack on a substrate, covered by an encapsulation layer and comprising first and second current collector/electrode assemblies, a solid electrolyte and electrical connections of the second current collector/electrode assembly to an external electrical load. The electrical connections are formed by at least two electrically conductive barriers passing through the encapsulation layer from an inner surface to an outer surface of the encapsulation layer. Each of the barriers has a lower wall in direct contact with a front surface of the second current collector/electrode assembly and an upper wall opening onto the outer surface of the encapsulation layer. The barriers form a compartmentalization network within the encapsulation layer. | 12-20-2012 |
20130095381 | MICROBATTERY AND METHOD FOR MANUFACTURING A MICROBATTERY - A microbattery that includes, in succession starting from a first substrate: a first current collector, a first electrode, an electrolyte, a second electrode consisting of a solder joint, a second current collector and a second substrate. Additionally, a method for manufacturing a microbattery, which includes the following steps: forming a thin-film multilayer including, in succession from the first substrate, a first current collector, a first electrode, an electrolyte and a first metal film; forming a second current collector on a face of a second substrate; and forming a second electrode by soldering the first metal film and the second current collector together, said substrates being placed facing each other during assembly. | 04-18-2013 |

20140248541 | SOLID ELECTROLYTE FOR LITHIUM BATTERY, COMPRISING AT LEAST ONE ZONE OF LITHIUM-CONTAINING GLASS CERAMIC MATERIAL AND METHOD OF PRODUCTION - At least one zone made of lithium-containing glass-ceramic material, in a solid electrolyte for a lithium battery, is formed from a lithium-containing ceramic material, advantageously in the form of a layer such as a thin film It is obtained by melting of at least a part of the lithium-containing ceramic material, followed by a recrystallization heat treatment. Melting is obtained by a laser beam irradiation operation, which enables fabrication of the solid electrolyte to be performed directly on a multilayer stack comprising certain active components of the lithium battery. | 09-04-2014 |
20150027979 | LITHIUM MICROBATTERY FABRICATION METHOD - The method for fabricating a lithium microbattery is performed from a stack of layers successively including: a first layer made from a first material, a second layer made from a second material, a solid electrolyte layer and a first electrode. The method further includes etching to form a first pattern made from the first material and a second pattern made from the second material, the second pattern defining a covered area and an uncovered area of the electrolyte layer. The uncovered area is then etched using the second pattern as etching mask. After etching of the first pattern, a lithium-based layer is formed on the second pattern, the lithium-based layer and the second pattern forming a second lithium-based electrode. | 01-29-2015 |
