Definitions
- Electrochemical device with solid electrolysis and alkaline ion conductive solid and with aqueous electrolyte
- the present invention relates to an electrochemical device, in particular a rechargeable battery, comprising both a saturated aqueous electrolyte and a solid electrolyte membrane conducting alkaline cations, these two electrolytes being separated from each other by a film of organic polymer.
- the specific energy density (expressed in Wh / kg) of batteries remains the main limitation for their use in portable equipment, such as portable electronics or electric vehicles.
- the energy limitation of these batteries is largely related to the performance of the materials that compose it.
- the best negative electrode materials currently available generally have a specific capacity of between 300 to 350 Ah / kg. This is of the order of 100 to 150 Ah / kg only for the materials of the positive electrode.
- the advantage of metal-air systems lies in the use of a positive electrode of infinite capacity.
- the oxygen consumed at the positive electrode does not need to be stored in the electrode but can be taken from the ambient air.
- the capacity of the battery then depends only on the capacity of the negative electrode and the capacity to store the product of the reduction of oxygen, ie the lithium or sodium hydroxide formed in the Positive electrode compartment during the discharge of the battery.
- the air electrode needs an aqueous medium, basic or acid, to be able to function optimally.
- the metallic lithium or the metallic sodium used for the negative electrode is too reactive towards the water and its formation in the presence of water, during the recharge, is impossible because the reduction of the Water operates at much lower voltages, preventing the formation of lithium or sodium metal.
- a watertight physical barrier is therefore required between the lithium or sodium metal negative electrode compartment and the positive electrode compartment containing an aqueous electrolyte. This physical waterproof barrier must, however, pass selectively the metal cations of the aqueous electrolyte to the negative electrode and in the opposite direction.
- Li Super Ionic Conductor (LISICON) or “Na Super Ionic Conductor” (NASICON)
- LISICON Li Super Ionic Conductor
- Na Super Ionic Conductor a family of ceramic materials that meet these requirements. These materials have advantageously high conductivities of up to 10 " or even 10 " 3 S / cm at 25 ° C and exhibit good chemical stability with respect to the aqueous electrolyte in the positive electrode compartment (electrode air).
- their reactivity with lithium or sodium metal in the anode compartment is very important and it is essential to isolate them in a known manner from lithium or sodium metal by a protective coating, for example based on a glass of oxynitride. phosphorus and lithium (LiPON) or phosphorus and sodium oxynitride (NaPON).
- the concentration of alkali metal hydroxide therefore increases in the aqueous electrolyte during the discharge of the battery and decreases during charging of the battery when the alkaline ions migrate back to the negative electrode compartment to be reduced. and that the hydroxyl ions are oxidized at the oxygen-releasing electrode (positive electrode operating during charging of the battery).
- This problem is particularly important and troublesome for lithium hydroxide which has a solubility in water at 20 ° C of only about 5.2 moles / liter. It is less so for sodium hydroxide which has a solubility in water about five times higher than lithium hydroxide.
- the present invention is based on the discovery that the undesirable formation of such a dense crystallization layer of LiOH or, to a lesser extent NaOH measurement, at the solid electrolyte / aqueous electrolyte interface can be completely prevented by the presence of a thin layer of a suitable organic polymer at this interface.
- the subject of the present invention is therefore an alkaline cation-conducting ceramic membrane covered, on at least a part of at least one of its surfaces, with a layer of an insoluble, chemically stable cation-conducting organic polyelectrolyte in which water at basic pH, or very basic, that is to say greater than 14.
- the ceramic conductive membrane of alkaline cations is preferably a ceramic membrane conductive of sodium ions or lithium ions, preferably lithium ions.
- Such metal ion-conducting ceramic membranes are known and are sold, for example, under the names Lithium Ion Conducting Glass Ceramic (LIC-GC) by the company Ohara Inc., Japan. These are ceramics of formula Li 1 + X (M, Ga, Al) x (Ge 1- y Ti y ) 2-x (PO 4 ) 3 where M represents one or more metals selected from Nd, Sm, Eu , Gd, Tb, Dy, Ho, Er, Tm and Yb, and where 0 ⁇ x ⁇ 0.8 and 0 ⁇ y ⁇ l, 0. Ceramic membranes of this type are also known in the literature under the name LISICON (Li Super Ionic Conductor).
- Sodium-ion-conducting ceramics are, for example, materials of the formula Na 1 + x Zr 2 Si x P 3- x 0 1 2 where 0 ⁇ x ⁇ 3.
- the thickness of the conductive ceramic membrane of alkali metal cations depends on the dimensions of the membrane. The larger the surface area, the thicker the ceramic must be to withstand mechanical stress. In electrochemical devices, however, it is generally sought to use, as far as possible, solid electrolytes thin.
- r denotes the resistivity of the electrolyte, its thickness and its surface.
- the solid electrolyte membrane used in the present invention advantageously has a thickness of between 30 ⁇ and 500 ⁇ , preferably between 50 ⁇ and 160 ⁇ .
- the thickness of the membrane must be increased accordingly or the membrane must be reinforced and supported by a reinforcing structure, for example bars or a resin grid, glued on a surface. or both sides of the membrane and leaving free the largest surface thereof, i.e. at least 80, preferably at least 90% of the surface of the solid electrolyte membrane.
- This ceramic membrane is coated on at least one of its surfaces with a layer of a cation-conductive organic polymer which is insoluble in water at basic pH and chemically stable at basic pH.
- the term "cation-conducting organic polymer” or “cation-conducting organic polyelectrolyte” means a polymer having a plurality of electrolytic groups. When such a polymer is brought into contact with water, the electrolytic groups dissociate and negative charges, associated with cations (counter-ions), appear on its backbone. The charge of the polymer is dependent on the number of electrolyte groups present and the pH of the solution.
- Such a cation-conducting polyelectrolyte therefore has an intrinsic capacity for cation conduction and must be distinguished from solid electrolytes based on polymers impregnated with salts, for example the electrolytes of lithium metal polymer (LMP) batteries which consist of a polymer neutral, such as polyethylene oxide, impregnated with lithium salt.
- LMP lithium metal polymer
- Such electrolytes of the LMP batteries would indeed be inappropriate for the application envisaged in the present invention because they are soluble in water and chemically unstable in strongly basic media.
- Such cation-conducting organic polymers are known and are typically used in fuel cell type PEMFC (English polymer electrolyte membrane fuel cell) or for chlor-alkali electrolysis, where they are used as electrolyte solid.
- water-stable polymer at basic pH is understood to mean a polymer which, when immersed for one week in water at pH 14 and 50 ° C, shows no detectable chemical degradation. nor any loss of ionic conductivity.
- this insoluble and water-stable polymer at basic pH is a poly-acid polyelectrolyte carrying a number of negatively charged groups (anions). It is these negative charge groups, linked to the polymer backbone and associated with cationic counterions, which are indeed responsible for the cationic conductivity of the polymer layer covering the ceramic.
- the organic polymer must have a conductivity of sufficient Li + or Na + ions, but need not be selective with respect to a certain type of cation, this selectivity being provided by the conductive ceramic of underlying cations.
- the equivalent weight should not be too low because a too high concentration of negative charges could make the polymer soluble in water and the aqueous electrolyte.
- the lower limit of the equivalent weight range will depend, among others, on the chemical nature of the polymer and in particular the hydrophobic nature of the uncharged comonomers.
- a polymer having a very hydrophobic skeleton is indeed insoluble in water for equivalent weights lower than those of polymers having a less hydrophobic skeleton.
- the skilled person will have no problem to adjust the equivalent weight of the polymer to the lowest possible value which however allows to maintain insolubility in water.
- the equivalent weight of the organic polymer is preferably between 600 and 1800 g / mol, in particular between 700 and 1500 g / mol of acid groups.
- the organic polymer is preferably a halogenated organic polymer, and a fluoropolymer is particularly preferred. As indicated above, this polymer must carry acid groups. These acid groups can be strong or weak acids, the pH of use, generally very high, ensuring a sufficient dissociation rate for weak acids.
- a particularly preferred example is a copolymer of tetrafluoroethylene and a comonomer carrying an acid group, preferably a polymer of formula
- X represents a -COO group "or a group -S0 3", preferably -SO 3 "group, and M + represents a proton or a metal cation.
- Preferred such polymers are known and available on the market for many years under the name Nafion ®. Dispersions or solutions of this polymer may be uniformly deposited on the ceramic membranes for example by spraying, immersion, centrifugation, roller or brush. After evaporation of the solvent phase, the polymer coated ceramic is preferably heat-treated, for example for one hour at about 150 ° C in air, in order to stabilize the polymer layer. After deposition, the polymer is in proton form. The protons will be exchanged for Li + or Na + ions when immersed in lithium hydroxide or sodium hydroxide solutions.
- the equivalent weight is preferably between 1000 and 1200 g / mol of acid groups.
- the thickness of the organic polymer layer after deposition, drying and a possible heat treatment is generally between 1 and 50 ⁇ , preferably between 2 and 20 ⁇ , in particular between 2 and 10 ⁇ .
- the polymer layer should be thick enough to be stable and covering and effectively prevent crystallization of the alkali metal hydroxide. Larger thicknesses, that is to say greater than 50 ⁇ , could certainly be envisaged, but would undesirably increase the strength of the organic polymer layer.
- the cation-conductive organic polymer, insoluble and chemically stable in water at basic pH only covers one of the two surfaces of the ceramic membrane and the other surface is coated with a protective coating based on Li 3 N, Li P, LiI, LiBr, LiF, lithium and phosphorus oxynitride (LiPON) or based on sodium and phosphorus oxynitride (NaPON), preferably a LiPON or NaPON coating.
- This coating provides protection against attack by the negative electrode material.
