Definitions
- the present invention relates to batteries, in particular to thin film batteries, and more particularly to the encapsulation systems which protect them.
- the invention relates more particularly to the field of lithium ion batteries, which can be encapsulated in this way.
- the invention also relates to a new process for manufacturing thin-film batteries, having a novel architecture and encapsulation which gives them a particularly low self-discharge, and an improved service life.
- lithium ion batteries are very sensitive to humidity.
- the market requires a lifespan of more than 10 years; it is necessary to provide an encapsulation which makes it possible to guarantee this lifespan.
- Thin-film lithium ion batteries are multilayer stacks that include electrode and electrolyte layers typically between about one ⁇ m and ten ⁇ m thick. They can comprise a stack of several elementary cells. It is observed that these batteries are sensitive to self-discharge. Depending on the positioning of the electrodes, in particular the proximity of the edges of the electrodes for multilayer batteries and the cleanliness of the cutouts, a leakage current may appear on the ends, a creeping short circuit which decreases the performance of the battery. This phenomenon is exacerbated if the electrolyte film is very thin.
- the cyclical variation in the volume of the anode materials also induces a cyclical variation in the volume of the battery cells. It thus generates cyclical stresses on the encapsulation system, liable to initiate cracks which are at the origin of the loss of tightness (or even of integrity) of the encapsulation system. This phenomenon is another cause of the decrease in the performance of the battery during its life.
- lithium ion batteries are very sensitive to air and in particular to humidity.
- Mobile lithium ions react spontaneously with traces of water to form LiOH, leading to calendar aging of the batteries.
- All lithium ion conductive insert materials and electrolytes are not reactive with moisture.
- Li 4 TisOi2 does not deteriorate on contact with the atmosphere or traces of water.
- the inserted lithium surplus (x) is, for its part, sensitive to the atmosphere and reacts spontaneously with the traces of water to form LiOH. The reacted lithium is then no longer available for storing electricity, leading to a loss of battery capacity.
- Document US 2002/071 989 describes a system for encapsulating an entirely solid thin-film battery comprising a stack of a first layer of a dielectric material chosen from alumina (AI2O 3 ), silica (S1O2 ), silicon nitride (S1 3 N4), silicon carbide (SiC), tantalum oxide (Ta 2 0s) and amorphous carbon, a second layer of a dielectric material and a layer sealing disposed on the second layer and covering the entire battery.
- a dielectric material chosen from alumina (AI2O 3 ), silica (S1O2 ), silicon nitride (S1 3 N4), silicon carbide (SiC), tantalum oxide (Ta 2 0s) and amorphous carbon
- a first proposed system comprises a layer of parylene covered with an aluminum film deposited on the active components of the battery. However, this system of protection against the diffusion of air and water vapor is only effective for about a month.
- a second proposed system comprises alternating layers of parylene (500 nm thick) and metal (about 50 nm thick). The document specifies that it is preferable to coat these batteries with a further Ultraviolet (UV) cured epoxy layer to reduce the rate of degradation of the battery by atmospheric elements.
- UV Ultraviolet
- the Applicant has also proposed, in document WO 2019/215 410, various examples of layers, intended to form respectively anodic and cathodic contact members.
- first example there is a first thin layer deposited by ALD, in particular of a metallic nature.
- second layer of epoxy resin charged with silver is provided.
- the first layer is a material loaded with graphite, while the second layer comprises metallic copper obtained from an ink loaded with nanoparticles.
- the surface area of these welds exposed to the atmosphere remains very small, and the rest of the packaging consists of aluminum sheets sandwiched between these polymer sheets.
- two aluminum sheets are combined in order to minimize the effects associated with the presence of holes, defects in each of these aluminum sheets. The probability that two defects on each of the strips are aligned is greatly reduced.
- the encapsulation system must be watertight and hermetic, must envelop and completely cover the component or battery, and must also enable the edges of electrodes of opposite signs to be galvanically separated in order to avoid any creeping short circuit.
- An objective of the present invention is to remedy at least in part the drawbacks of the prior art mentioned above.
- Another object of the present invention is to provide lithium ion batteries with a very long service life and low self-discharge.

- the battery cells are rigid and dimensionally stable, linked to the initial choice of materials.
- the encapsulation system obtained according to the invention is effective.
- the invention provides for an encapsulation system which can and which is advantageously deposited under vacuum.
- the batteries according to the invention do not contain polymers; on the other hand, they can contain ionic liquids. In fact, they are either entirely solid or of the “quasi-solid” type in which case they include an electrolyte based on a nanoconfined ionic liquid base. From an electrochemical point of view, this nanoconfined liquid electrolyte behaves like a liquid, insofar as it provides good mobility to the cations it conducts. From a structural point of view, this nano-confined liquid electrolyte does not behave like a liquid, because it remains nano-confined and can no longer come out of its prison even during treatment under vacuum and / or at high temperature.
- the batteries according to the invention which contain an electrolyte based on nanoconfined ionic liquid, can therefore undergo treatments under vacuum, and / or under vacuum and at high temperature, with a view to their encapsulation.
