Definitions
- the present invention relates to new cathode compositions and their uses, in particular in electrochemical generators.
- the invention also relates to electrochemical cells comprising at least one electrode comprising a composition according to the invention.
- A Mg, Zn, Al, Fe, Cr, Co, Mn, Ni, Zn, Ga, 0 ⁇ x, y, a, f ⁇ 1.
- Another disadvantage is the low mass capacity of these materials, between 90 and 130 mAh / g. These materials are used in electronics, and the potential standard of 4.1 - 4.2 V is required in most portable electronics systems.
- these materials are non-toxic and formed from abundant elements.
- operating in a very narrow potential range is an advantage in terms of simplification of the electronics, especially since the resistance of these materials to overcharging and over-discharging is excellent.
- these materials have an electronic conductivity too low and require the addition either of a large mass fraction of carbon for their use in primary or secondary generators, or of an extremely thin deposit of carbonaceous material distributed over the surface of the grains. In this case, the apparent density, therefore the connectivity of the grains, must be as high as possible so as to obtain a good electronic exchange. This results in the need for large volume fractions of double phosphate in the composite material serving as cathode.
- the invention relates to a positive electrode composition containing at least one mixed oxide of spinel or lamellar structure of general formula.
- A Mg, Zn, Al, Fe, Cr, Co, Mn, Ni, Zn Ga, 0 ⁇ x, y, a, f ⁇ l,
- the mixed oxide is preferably Lii- x Co ⁇ 2 or Li ⁇ _ x Nii-yC ⁇ y ⁇ 2 for which 0.1 ⁇ y ⁇ 0.4, while the mixed phosphate is preferably Li ⁇ _
- the proportion of mixed phosphate relative to the mixed oxide is between 5 and 95% by weight, preferably between
- the mixed phosphate can be covered on the surface with a homogeneous conductive carbon-based deposit or with a pyrolyzed organic material.
- the active cathode mixture can be added with a polymer serving as a binder and optionally as an electrolytic conductor by addition of a salt containing at least partly lithium ions, and optionally with a polar liquid.
- the active cathode mixture can be added with an electronic conductor allowing exchanges between the current collector and the grains of electrode material, in particular carbon black, graphite or their mixture.
- the invention also relates to an electrochemical cell comprising at least one electrode containing at least one material consisting of a composition as defined above.
- this electrochemical cell comprises a positive electrode of composition as defined above, and it functions as a primary or secondary battery, or as a super-capacity.
- the electrolyte is a polymer, solvating or not, optionally plasticized or gelled with a polar solvent and containing in solution one or more metal salts, in particular a lithium salt.
- the electrolyte can also be a polar liquid containing in solution one or more metal salts, in particular a lithium salt, optionally immobilized in a microporous separator, in particular a polyolefin, a polyester, nanoparticles of silica, alumina or lithium aluminate LiA10 2 or a mixture thereof as a composite.
- a metal salts in particular a lithium salt
- a microporous separator in particular a polyolefin, a polyester, nanoparticles of silica, alumina or lithium aluminate LiA10 2 or a mixture thereof as a composite.
- the polymer containing a salt and optionally a polar liquid is preferably formed from oxyethylene, oxypropylene, acrylonitrile, vinylidene fluoride units, esters of acrylic or methacrylic acid, esters of itaconic acid with alkyl groups or oxa-alkyls, in particular containing the oxyethylene units.
- the polymer contains in particular powders of nanoparticles such as silica, titanium oxide, alumina, LiA10 3 .
- the polar liquid is preferably chosen from cyclic or linear carbonates, carboxylic esters, alpha-omega ethers of oligoethylene glycols, N-methylpyrrolididone, gamma-butyrolactone, tetraalkyl sulfonamides and their mixtures, a fraction of the atoms of hydrogen which may be substituted by fluorine atoms.
- the negative electrode of the battery according to the invention can contain metallic lithium or one of its alloys, in particular with aluminum, a compound for inserting lithium into carbon, in particular graphite. or the pyrolytic carbons, LiFe0 2 , Li 2 Mn 2 0 or Li 4 Ti 5 0 ⁇ 2 or the solid solutions formed between these oxides.
- the current collector of the electrode containing the electrode material according to the invention is made of aluminum, optionally in the form of expanded or expanded metal.
- the power capable of being delivered by these systems is greater than that obtained with the oxides used alone in the cathode mixture, in particular when very high powers are required.
- Figure 1 shows charge and discharge profiles at different speeds obtained at room temperature for LiCo0 2 and LiFeP0 4 batteries.
- Figure 2 represents charge and discharge profiles at different regimes obtained at room temperature for batteries containing a mixture composed of 72% LiCo0 2 and 28% LiFeP0 4 .
- Figure 3 represents the evolution of the capacity supplied as a function of the intensity of the charge and discharge current for batteries containing
- LiCo0 2 between 4.1 and 3 V
- LiFeP0 4 between 4.1 and 2.5 V
- a mixture composed of 72% LiCo0 2 and 28% of LiFeP0 4 between 4.1 and 2.5 V and between 4.1 and
- Figure 4 shows the charge and discharge profiles of batteries containing LiMn 2 0 4 on the one hand and a mixture of LiMn 2 0 4 and LiFeP0 4 on the other hand.
- the electrodes containing one or mixtures of the two families of the aforementioned electrode materials, double oxides or double phosphates can function advantageously, whether in terms of capacity and available power. This behavior is unexpected with regard to the dilution and the decrease in the contacts between grains of phosphate that these mixtures imply.
- the grains of phosphate-based materials are very poorly conductive and cannot ensure a continuum of high electronic conductivity in the mixture, a condition necessary for rapid electrochemical kinetics.
- the conductive coating possibly deposited on the surface of the phosphate grains which is the subject of US Pat. No.
- Cathode composed of a mixture of LiFeP0 4 and LiCo0 2
- the cathodes consist of a mixture of active material, carbon black, and a binding agent (PVDF in solution in N-methyl pyrolidone) in the proportions 85: 5: 10.
- PVDF in solution in N-methyl pyrolidone
- the composite is spread on a collector aluminum current. After drying, 1.3 cm electrodes with a capacity of about 1.6 mAh are cut out with a cookie cutter.
- the batteries are assembled in a glove box, under an inert atmosphere.
- the measurements were carried out in an electrolyte containing LiC10 1M in a mixture EC: DMC 1: 1.
- the anode consists of lithium.
- the tests are carried out at room temperature.
- the batteries containing LiCo0 2 alone as well as the mixture were charged in galvanostatic mode up to 4.1 V with maintenance of the potential until the current is less than 25 micro-amperes.
- the battery containing LiFeP0 4 was generally charged up to 4.1 V except for the 5C regime where the maintenance in potential was imposed.
- the cathodes consist of a mixture of active material, carbon black, and a binding agent (PVDF in solution in N-methyl pyrolidone) in the proportions 90: 3: 7.
- the composite is spread on a collector aluminum current. After drying, electrodes of 1.3 cm and about 11 mg of active material are cut out with a cookie cutter.
- the batteries are assembled in a glove box, under an inert atmosphere.
- the measurements were carried out in an electrolyte containing LiC10 4 1M in a mixture EC: DMC 1: 1.
