Technical Field

The present invention relates to the field of stretchable electronics, and more particularly to the field of deformable electrical energy storage elements or accumulators.

Background

Many studies have aimed at developing a deformable capacitor or battery.

It is particularly known to deposit on a stretchable substrate an island-like array of millimetre-sized active electrodes in the form of thin layers connected to each other by meanders (serpentines) acting as stretchable current collectors. This configuration allows for 300% elongation, but has the disadvantage of activating most of the surface for the serpentine interconnect. Thus, the active material of the battery occupies less than 30% of the total surface.

It is also known to deposit metal contacts on pre-stretched active material, thereby creating a configuration in the form of a "wavelet" when the pre-stretched substrate has returned to its original shape. The limitations of this method are related to the initial draw-down rate, which is usually rather low.

Finally, it is also known to weave fibers with electrical energy storage properties, then to naturally ensure ductility through weaving. A disadvantage of this approach is that it requires all the multilayer electrochemical bodies of the lithium ion battery to be contained within a very limited volume of the fiber.

Detailed Description

The known energy accumulator consists of the following elements:

a first current collector in contact with the negative electrode, called negative electrode, which releases electrons in the circuit during discharge.

-a second current collector in contact with a positive electrode, called positive electrode, which captures electrons from the circuit during discharge.

-separators impregnated with electrolytes, which allow to prevent short circuits while ensuring the transport of ions coming from the different electrochemical reactions occurring at the electrodes.

When the accumulator is charged, the charge transfer (electron and ionic species) occurs in the opposite direction.

It is also known that some materials of the polymeric type, known as self-healing polymers, have the specific property of being spontaneously regenerated in the event of mechanical breakage inside the material, by the effect of a spontaneous reaction of local polymerization which allows the material to be reconstructed at the site of the breakage.

The accumulator according to the invention is characterized on the one hand by the shape of the current collectors, which are themselves elongated and folded back, i.e. in such a shape that they look like a serpentine, and on the other hand by the fact that the negative and positive electrodes are configured as a row of micropillars, the bottom of which is located on their respective current collector.

According to one embodiment of the invention, each current collector is fabricated on either a flexible substrate, such as PET, polyimide, KAPTON, or a suitable substrate that is stretchable, such as Polydimethylsiloxane (PDMS) or polyurethane.

The material of the current collector may be selected from various known conductive materials, for example, metals such as gold, copper, titanium, or aluminum.

The material deposition method may be selected from one of the known methods, for example a metal vapour deposition method, a lamination method or more recently a technique such as printing of the conductive material by screen printing/ink jet printing. The fabrication of the serpentine pattern may additionally be performed by allowing the mask that defines the deposition area for the current collector to deposit material. They can also be made subtractively by photolithography or by laser lithography, electron or ion beam lithography.

Fig. 1 shows a top view of a flat blade-shaped substrate 1 on which a current collector consisting of several meanders 2a, 2b are deposited, these meanders being in contact with a common portion 3 constituting a pole of an electrical energy storage element. The serpentine is shaped to elongate and fold back on itself, with the advantage of being able to deform and stretch many times without disrupting the physical and electrical continuity of the current collector. The width of the lines of these meanders is of the order of one hundred microns or less, preferably between 100 and 400 μm. The precise shape of the serpentine is determined to maximize the surface of the current collector without compromising its ductility. The serpentine may have a corrugation periodicity in one direction to support only uniaxial traction, or in both directions to support biaxial deformation of the substrate. Examples of serpentine meshes having periodicity in both directions are shown in fig. 6a, 6b and 6 c.

According to one embodiment of the invention, each current collector is associated with an electrode deposited on said current collector, said electrode being configured as a group of micropillars 4, the micropillars 4 having a substantially cylindrical shape, one of the bases of each cylindrical pin being placed on a serpentine, as shown schematically and perspectively in fig. 3. In fig. 2, a schematic top view shows an imprint of a micropillar forming one of the electrodes on one of the serpentine-shaped current collectors.

The diameter or width of the bottom of the microcolumn is of the order of a few micrometers, preferably between 1 μm and 100 μm, more advantageously between 2 μm and 10 μm.

The height of the microcolumns is of the order of tens of microns, preferably between 1 μm and 1000 μm, more advantageously between 10 μm and 100 μm.

The spacing between the micropillars is of the order of a few microns, preferably between 0.1 μm and 20 μm, more advantageously between 2 μm and 10 μm.

The active material used to form the negative electrode may be selected from lithiated and/or sodium-containing active materials known for negative electrode function, such as metallic lithium; sodium metal; silicon; bismuth; intermetallic compounds such as SnSb; lithiated nitrides, e.g. LiMyN₂Wherein M represents Fe, Co, Ni, Mn or Cu and y is the stoichiometric coefficient of the metal; carbon compounds, e.g. carbon, LiC₆Or graphene; tin alloys, such as Sn or SnM, wherein M represents Fe, Co, Ni, Mn or Cu; tin oxides, e.g. SnO and SnO₂(ii) a Transition metal oxides, e.g. TiO₂(ii) a And lithiated oxides, e.g. Li₄Ti₅O₁₂(LTO)。

The active material used to form the positive electrode may be selected from lithiated and/or sodium-containing active materials known for use in positive electrode functions, such as manganese oxides, in particular MnO₂、LiMn₂O₄、LiNi_0.5Mn_1.5O₄；LiCoO₂、LiTiS₂(ii) a Vanadium oxides, e.g. V₂O₅、LiV₃O₈(ii) a Inorganic polyanionic compounds, e.g. phosphates, e.g. LiMPO₄Wherein M represents Fe, Co, Ni, Mn or Cu; fluorophosphates, e.g. LiFePO₄F or e.g. Li₂Co_1-xM_xPO₄F, wherein M represents Fe or Mn and x is the stoichiometric coefficient of the metal; or copper phosphates, e.g. Cu₃(PO₄)₂。

the method of depositing and structuring each electrode as a microcolumn is selected from known layer deposition methods to suit the active material in question. In particular, conventional methods such as spin coating, dip coating, doctor blading or electrodeposition can be considered.

According to one embodiment of the invention, a first substrate 1 is placed facing a second substrate 1', said first substrate 1 being provided with its serpentine-shaped negative current collector 2a, 2b,.. the negative electrodes 4 are deposited on the serpentine-shaped negative current collector 2a, 2b,. forming micro-pillar rows, said second substrate 1' being provided with its serpentine-shaped electrode current collector 2' a, 2' b,. the positive electrodes 4' are deposited on the serpentine-shaped electrode current collector 2' a, 2' b,. forming micro-pillar rows. The distance separating the two faces facing each other must be large enough so that there is no electrical contact between the microcolumns of the negative electrode and the microcolumns of the positive electrode and therefore no short circuit. Fig. 4 schematically shows such a configuration of elements constituting the electric energy storage element. The gap 5 separates the two substrates 1 and 1'; the gap 5 also separates the negative micro-pillars 4 from each other and the positive micro-pillars 4 'from each other, and finally separates the negative micro-pillars 4 from the positive micro-pillars 4'. The voids 5 are filled with an electrolyte made of a self-healing polymer type material.

The electrolyte is made of a material selected from the list of self-healing polymeric-type materials; the self-healing polymer electrolyte will be obtained by combining two other species with different functions:

self-healing function due to the presence of pendant hydrogen bonds;

-an ion conducting function;

thus, the self-healing monomers are functionalized with other ion-conducting polymers such as polyethylene oxide (PEO), polyethylene glycol (PEG), Polystyrene (PS) having different molar masses, subjected to controlled radical polymerization, obtaining self-healing polymers. Hard blocks such as PS, PMMA or soft blocks such as PABu may be grafted to control the hardness and stretchability of the self-healing monomer.

As preferred examples of the deformable energy accumulator according to the invention, mention may in particular be made of deformable energy accumulators in which the electrolyte is POE-b-poly (5-acetamidopentylglycolate) or POE-b-PS-g-poly (5-acetamidopentylglycolate) or PEG-b-6- (2-ureido-4-pyrimidinone) hexylacrylate or a polymer whose main unit is selected from one of the following.

The method of depositing the electrolyte between the two substrates and the electrode microcolumns is selected from known methods and is suitable for the block copolymer under consideration.

In the case of stretching the electrical energy storage element, the construction of the electrodes as spaced microcolumns has the first advantage of avoiding the formation of cracks in the material constituting the electrodes or at the interface between the electrodes and the current collector.

This configuration has a second advantage; it allows better withstand the variations in electrode volume caused by the continuous extraction/insertion of Li + ions in the case of lithium ion batteries and avoids contact losses at the interface between the electrolyte and the electrode.

Furthermore, a third advantage of this configuration as a microcolumn is that it increases the contact surface between the electrodes and the electrolyte, which further increases the energy and power density available per surface unit.

Finally, a fourth advantage consists in that a significant reduction in the electrical resistance, called series resistance, between the electrode and the current collector is ensured by the direct electrical contact between the electrode and the current collector, unlike the long serpentine interconnections of the prior art.

Finally, the use of self-healing polymers will help maintain an intact and continuous interface between the electrodes and the electrolyte after the cell is stretched.

The invention also relates to a method of manufacturing the deformable memory element. The method comprises the following steps:

a. preparing a first substrate and a second substrate;

b. depositing at least one first current collector (2a, 2 b.) on at least one part of the face of the first substrate, close to and along at least one first curvilinear portion, the length of which is greater than the distance between its two ends,

c. depositing at least one second current collector (2a', 2 b.) -on at least a part of the face of the second substrate, close to and on each side of at least one second curve, the length of which is greater than the distance between its two ends,

d. depositing a negative electrode consisting of a first set of pillars (4) on at least one first current collector (2a, 2 b.), the pillars of the first set being spaced from each other on the surface of the first current collector,

e. depositing a positive electrode consisting of a second set of pillars (4') on at least one second current collector (2' a, 2' b.,), the pillars of the second set being spaced from each other on the surface of the second current collector,

f. depositing an electrolyte on the faces of the first and second substrate on which the at least one first and second current collectors are respectively deposited, while immersing the pillars of negative (4) and positive (4') electrodes in the electrolyte, and then placing these faces facing each other

Or

The faces of the first and second substrate on which the at least one first and at least one second current collector are respectively deposited are placed facing each other, then the electrolyte is deposited in the volume (5) delimited by these faces, while the columns of negative (4) and positive (4') electrodes are immersed in the electrolyte.

The order in which the steps are mentioned does not affect the order in which they must be performed.

Fig. 7 shows an embodiment of a surface of the deformable energy store according to the method, more precisely according to the first option of step f of the method, by means of an intermediate product formed in different steps.

Thus, an intermediate product is shown in fig. 7a, resulting from the combination of step a with the placement of a first substrate, followed by the first part b1 of step b with the deposition of a first current collector and the first part d1 of step d with the deposition of a negative or positive electrode (4, 4'). At this intermediate stage, the serpentine regions of the current collector and the microcolumns of the electrode have not yet been formed.

Then, forming the electrode microcolumn by photoetching; this is the second part d2 of step d, the result of which is shown in fig. 7 b.

The second part b2 of step b is then used to form the meanders 2a, 2b by laser engraving, the results of which are shown in figure 7 c.

Finally, with the last step f, the electrolyte is deposited by a method called "dip coating", the intermediate result of which is schematically shown in fig. 7 d.
