Definitions
- the present invention relates to a method for removing water and other protic contaminants from organic liquid electrolytes.
- the lithium batteries common today normally contain water-free, liquid, ion-conducting electrolytes in which conductive salts such as LiPF 6 , LiBF 4 , LiCI0 4 , lithium imide, lithium methide or lithium chelate complexes such as lithium bis (oxalato) borate in dissolved Form.
- conductive salts such as LiPF 6 , LiBF 4 , LiCI0 4 , lithium imide, lithium methide or lithium chelate complexes such as lithium bis (oxalato) borate in dissolved Form.
- protic compounds such as water
- the gaseous products (HF, POF3, etc.) formed during the hydrolysis of fluorine-containing conductive salts are highly caustic and harmful to the other battery components, such as the cathode materials.
- HF leads to the resolution of angan spinels and disrupts the cover layer on the electrode materials, which is important for a long service life.
- Borate electrolytes are also sensitive to water. In this case, insoluble hydrolysis products are formed, which impair the functional properties.
- JP 02087473 proposes to mix electrolyte solutions with a solvent which forms low-boiling azeotropes with water and to remove the water / solvent azeotrope by distillation.
- the . Disadvantages of this process are the undesirable contamination with the entraining solvent and the restriction to high-boiling electrolyte solvents
- JP 10338653 to accomplish the drying of electrolyte solutions by blowing dry inert gases has the disadvantage that very expensive (cleaned) inert gas has to be used and strong solvent losses occur or the discharged solvent vapors have to be condensed and recycled in a complex manner.
- DE 19827631 Another method described in DE 19827631 and in a similar form in JP 2000058119 is based on the physical adsorption of water and HF on specially pretreated aluminum oxide.
- the disadvantage of the adsorption process is the complex pretreatment of the Al oxide (drying for 4 weeks in a stream of nitrogen at 400 ° C).
- DE 19827630 describes a cleaning method for battery electrolytes which consists in bringing a solid-fixed base into contact with the electrolyte solution for the chemical adsorption of protic impurities and then separating the solid cleaning agent.
- the amine-containing, polymer-fixed cleaning agents are expensive and also require pretreatment (for example, four-day vacuum drying at 100 ° C.).
- Even modern supercapacitors can contain an organic electrolyte, which is usually a solution of an ammonium salt in an aprotic solvent with a high dielectric constant, such as acetonitrile or ⁇ -butyrolactone.
- the ammonium salts generally have perfluorinated anions such as PF 6 " or BF 4 " . These are electrochemically stable, not very nucleophilic and are not embedded in the active electrode masses.
- JP 11054378 and JP 11008163 propose adsorbents based on inorganic oxides, for example aluminosilicates, to be added to the electrolyte. These adsorbents can lower the water content and thus improve reliability, safety and current characteristics.
- the disadvantages of this method are, on the one hand, the necessary pretreatment of the adsorbents and, on the other hand, that the adsorbent remains in the finished condenser, so that the specific storage capacity is reduced.
- Organic liquid electrolytes are understood to mean solutions which contain lithium and / or ammonium salts with electrochemically stable anions in aprotic, polar, organic solvents.
- the object is achieved by a method for removing water and other protic impurities from an organic liquid electrolyte, the organic liquid electrolyte containing one or more insoluble ones Alkali metal hydride (s) is brought into contact and the resulting insoluble reaction by-products are separated. Removal of water and other protic impurities means the partial removal until complete removal.
- the binary hydrides of lithium (LiH) and sodium (NaH) used as preferred desiccants are relatively inexpensive in large quantities and are available in pure form. Although they are completely insoluble in the aprotic solvents used for lithium batteries, it was found that LiH, NaH and the other alkali metal hydrides KH, RbH and CsH are quickly effective with regard to the drying process and very low residual levels of protic impurities can be achieved.
- the hydridic drying agents used according to the invention are considerably more advantageous in terms of safety than the alkali metals themselves.
- EC ethylene carbonate
- DMC dimethyl carbonate
- PC propylene carbonate
- LOB lithium bis (oxaIato) borate
- the method according to the invention is applicable to all organic liquid electrolytes, for example solutions of
- Fluorides such as MPF 6 , MAsF 6 , MBF 4 perchlorates MCI0 4 lithium iodide Lil
- R F perfluorinated alkyl radical with 1-10 C atoms, also cyclic
- L bidentate ligand with two O atoms, e.g. Oxalate, catecholate, salicylate, whether or not partially or completely fluorinated
- Carbonates e.g. Dimethyl carbonate, diethyl carbonate, ethylene carbonate,
- Ethers e.g. Tetrahydrofuran, 2-methyltetrahydrofuran,
- Boric acid esters e.g. Tributyl borate, trimethyl borate
- Phosphoric acid esters e.g. Tributyl phosphate, triethyl phosphate, sulfur compounds, e.g. Dimethyl sulfoxide, sulfolane and mixtures thereof.
- the alkali metal reacts energetically and irreversibly with proton-active substances according to:
- the hydride is preferably added in portions to the liquid electrolyte.
- the content of proton-active substances for example water, should not exceed a certain upper limit of 0.6 mmol / g active H concentration, for example 1% water. More contaminated liquid electrolytes can also be dried in compliance with the safety precautions familiar to the person skilled in the art; however, it is advisable to use a different drying process for these cases first and only to carry out the final drying with the process according to the invention.
- drying process according to the invention can be carried out as described below by way of example.
- the moist and possibly contaminated with other proton-active liquid electrolyte is preferably added in portions with stirring with an alkali metal hydride.
- This process is preferably carried out in the temperature range between -20 and 150 ° C, particularly preferably 0 to 90 ° C.
- the drying process can easily be followed by measuring the developed gas volume. In some cases (mainly in the presence of significant amounts of acid, e.g. 0.1 mmol / g HCl) the gas evolution is quite violent and foaming occurs. Then cooling is required. In the other cases, the reaction is hardly noticeably exothermic.
- a post-reaction phase at room temperature or elevated temperature up to 90 ° C, sometimes up to 120 ° C is necessary to complete the drying.
- the amount of drying agent to be used is measured on the one hand by the “activity” of the metal hydride used and on the other hand by the concentration of the proton-active impurity - generally water.
- the water content is usually determined by Karl Fischer titration.
- the amount of desiccant used is preferably such that it determines at least that determined by Karl Fischer titration (or an alternative water determination) Corresponds to the amount of water.
- the desiccant can preferably be used in a stoichiometric excess (for example 2 to 100 times). The excess to be used in each case results from the activity of the hydride and the precise execution of the drying operation.
- the drying capacity depends on the "active surface" of the metal hydride, ie the finer the degree of distribution of the metal hydride, the better the effect.
- the drying ability of the metal hydride depends on the type of pretreatment.
- metal hydrides that have been in contact with air or moisture are "passivated” and generally need to be activated. This can be done by grinding in an inert gas atmosphere. This process can be spatially separated or in situ, i.e. take place during electrolyte drying.
- the clear solutions produced in this way have extremely low water contents (and also low levels of other proton-active ones Substances). Without further treatment, they can be used as electrolytes for galvanic cells, preferably lithium batteries, or electrolytic double-layer capacitors (supercapacitors).
- the respective crude electrolyte solution was placed in an inertized multi-necked flask equipped with a KPG stirrer, solid addition device and thermocouple. A sample was taken using a plastic syringe and its water content was checked by Karl Fischer titration.
- the degree of dryness depends on the selected conditions. In order to achieve residual water contents of ⁇ 20 ppm, drying times of 5 to 24 hours are necessary in the examples described.
