A microfluidic device for obtaining a homogenous plasma-reagent mixture includes a collection module for blood plasma arranged to passively separate the blood plasma from a drop of blood taken, a capillary channel in fluidic connection with said collection module and a storage reservoir for a reagent in fluidic connection with said capillary channel. The device also contains a mixing chamber in fluidic connection with said capillary channel equipped with a flow outlet. The volume of said storage reservoir for reagent being greater than the sum of the volumes of said capillary channel and of said mixing chamber, setting the reagent in motion, after saturation of said capillary channel with blood plasma, induces a flow of the homogenous plasma-reagent mixture from the flow outlet.

Microfluidic device for obtaining a plasma-reactive mixture and method of implementation

The present invention relates to an electricity storage unit comprising a plurality of energy storage cells () positioned side by side and a rigid enclosure () surrounding said cells (), comprising two separate parts (A,B), a first part of the enclosure comprising at least one reference wall, in particular made up of a lower wall (A), the unit comprising:&#x2014;at least one stop () made from an elastically deformable material that comprises at least one so-called main wall (), extending along a plane essentially normal to the reference wall (A) and which is positioned between two of the cells (), such that at least one stop () is placed between each pair of adjacent cells (), and&#x2014;pressing means () designed to bear on a face of each of the cells () in order to press each cell () against the reference wall (A), the pressing means () being removably fastened to the first part (A) of the enclosure ().

Electricity storage unit and assembly method for such a unit

The invention relates to a cover for covering a tubular element of a first electrical energy storage assembly (), said cover comprising a covering wall (). The cover is characterized in that it comprises a radially extending electroconductive tongue () comprising a contact face () intended to come into contact with a second adjacent storage assembly in order to electrically connect the two storage assemblies.

Cover for connecting energy storage assemblies

The invention relates to a module comprising at least two electrical energy storage assemblies (), each storage assembly comprising: a tubular element () comprising a so-called side face (), and at least one cover () for covering one of the ends of the tubular element. Said module is characterized in that it also comprises a connecting body () for electrically connecting the two assemblies, the connecting body comprising at least one portion, each portion being separate from at least one of the storage assemblies (), and the connecting body extends between the two storage assemblies such that the height of each storage assembly connected to the connecting body is equal to the height of a storage assembly that does not have a connecting body.

Connector arranged between two cylindrical energy storage assemblies

The invention relates to an electrical energy storage assembly comprising an envelope and a capacitive element () contained in the envelope, said envelope comprising: at least one side wall (); and two bottom walls () each located at an end of the side wall. Said storage assembly comprises at least one electroconductive intermediate connection part () to be arranged between the capacitive element and a bottom wall (), in addition to a covering plate () for covering the end of the capacitive element (), said covering plate () including at least one vent () for the passage of a fluid. The covering plate () is fixed to the capacitive element in such a way as to be in electrical contact therewith, and the intermediate connection part () is also fixed to the envelope in certain areas enabling a deformation of the bottom wall in relation to the intermediate connection part.

Long-term energy storage assembly comprising an intermediate connection part

The invention relates to a method for manufacturing a unit for storing electrical energy, comprising a cover and an outer casing, the method including a closing step () consisting of contactlessly applying a compressive force to one of the parts forming the storage unit, such that the cover and the outer casing are mechanically titled into one another so as to close the outer casing using the cover by means of the engagement of the shapes thereof.

Method for manufacturing a unit for storing electrical energy

The invention relates to a cover () for an energy storage unit, which is to be inserted at an end of a casing () in which a capacitive element () of the unit is arranged, the cover comprising at least one sidewall () which to be arranged opposite at least one sidewall of the casing and two end walls (), characterized in that a plurality of cavities () are provided in the cover, at least one first cavity () opening onto the sidewall(s) () and onto an end wall (), and at least one second cavity () opening onto the sidewall(s) () and onto the other end wall (), the first cavity or cavities opening onto the sidewall(s) () in one or more first portions extending over a portion of the periphery of the sidewall(s), while the second cavity or cavities () open onto the sidewall(s) () in one or more second portions extending over a portion of the periphery of the sidewall(s).

Cover for an energy storage unit, energy storage unit comprising said cover, and method for manufacturing such an energy storage unit

The invention relates to a method for connecting two energy storage assemblies () together, each energy storage assembly including a sealed metal housing, in which: a connector strip (), which is sized so as to contact the end surface of each of the housings, is positioned on the end surfaces () of two housings arranged side by side; and the strip is friction-stir welded to each of the housings.

Device and method for the friction-stir welding of an assembly for storing electricity

A method for sealing an impregnation orifice of an energy storage assembly including a case. The orifice is provided in one of the walls of the case and has an outer mouth and an inner mouth. At least one end portion of a head of a tool driven in rotation is inserted into the orifice through the outer mouth, in a direction corresponding to the axis of the orifice in order to heat an area of the case in the vicinity of the orifice. The head has at least a first transverse section, and a second transverse section that is smaller than the first transverse section. Once the area is heated, a translation of the tool in the direction of the inner mouth moves the material forming the walls of the orifice in the direction of the inner mouth, and the orifice is sealed by readhesion of the material.
