Definitions
- the invention relates to lithium bisoxalatoborate, Li [(C 2 0 4 ) 2 B], two processes for its preparation and the use of lithium bisoxalatoborate as the conductive salt in lithium ion batteries.
- LiPF 6 Lithium hexafluorophosphate
- This salt has the necessary prerequisites for use in high-energy cells, ie it is readily soluble in aprotic solvents, it leads to electrolytes with high conductivities, and it exhibits high level of electrochemical stability. Oxidative decomposition only occurs at potentials> approx. 4.5 V.
- LiPF ⁇ also has serious disadvantages, which are mainly attributed to its lack of thermal stability. In solution, dissociation in LiF and PF 5 takes place, albeit slightly, which can lead to cationic polymerization of the solvent caused by the Lewis acid PF 5 .
- lithium salts with perfluorinated organic residues are tested.
- Particularly noteworthy are the lithium trifluoromethanesulfonate, the lithium bis (trifluoromethanesulfonyl) imide and the lithium methides, the simplest of which is lithium bis (trifluoromethanesulfonyl) methide.
- the former salt does not give the electrolytes produced with it a sufficiently high conductivity.
- the last-mentioned salts have a conductivity equal to that of LiPF 6 , they are commercially uninteresting because of the complex production processes.
- the imide has a corrosive effect on aluminum sheets, which are used in many battery systems Current arresters are used. Because of the high fluorine content of the compounds, exothermic reactions with lithium are also to be feared under unfavorable conditions.
- Lithiu organoborate was examined as a further class of compound for use as a conductive salt.
- the safety problems associated with the formation of triorganoboranes, and their high price, their use in lithium ion batteries has not been seriously considered.
- the lithium borate complex salts [(R 1 ⁇ 2 B (OR 2 ) 2 ] Li described in DE 19633027 AI represent a significant advance.
- R 1 and R 2 are the same or different, R 1 and R 2 are optionally separated by a single or double bond connected to one another, R 1 and R 2 each individually or together have the meaning of an aromatic ring from the group phenyl, naphthyl, anthracenyl or phenanthrenyl, which can be unsubstituted or substituted one to four times by A or shark, with shark being fluorine or chlorine and A is alkyl having 1 to 8 carbon atoms, which in turn can be halogenated one to four times.
- a disadvantage of these compounds is, on the one hand, the improved stabilities of the non-fluorinated derivatives, which are by no means sufficient for the required 3 V systems.
- the unsubstituted lithium bis [1,2-benzenediolato (2-) -0, 0 "] borate (1-) decomposes when an anodic potential of 3.6 V is exceeded. This value is significantly below that of the standard conductive salt L ⁇ PF 6 (approx.4.5 V).
- Increasing fluorine substitution of the organic residue increases the oxidation stability up to a value of approx. 4 V for the perfluorinated compound. However, these values are still lower than for the standard salt L ⁇ PF 6 .
- the stability of the borates described continues to increase due to the formation of a covering layer during the cyclization, so that almost sufficient stabilities are achieved for some compounds.
- the stable compounds have high molar masses (for example 378 g / mol for the perfluorinated catecholato compound).
- the precursors required for the synthesis are also not commercially serious, but have to be prepared in a complex manner.
- compounds with CF-formings pose a potential safety risk because they are not thermodynamically stable to metallic lithium.
- the invention is therefore based on the object of eliminating the disadvantages of the prior art and of an electrochemically stable lithium compound which has good solubility r. the aprotic solvents used by the battery industry, and to create a process for their production.
- the object is achieved by the lithium compound lithium bisoxalatoborate, Li [(C 2 0) 2 B].
- the independent claims 2 and 11 indicate two different processes for the preparation of lithium bisoxalatoborate, claims 3 to 10 and 12 to 13 further develop the process and claim 14 specifies the use of the compound lithium bisoxalatoborate.
- Lithium bis (oxalatoborate) although it has no fluorine substituents, surprisingly has an excellent oxidation resistance. Solutions of this salt are stable in a mixture of ethylene carbonate (EC) and 1,2-dimethoxyethane (DME) up to a voltage of 4.6 V.
- EC ethylene carbonate
- DME 1,2-dimethoxyethane
- a 0.56 m solution in a 1: 1 mixture of EC and DME has a conductivity of 10.3 mS / cm at room temperature.
- the conductivity of lithium bisoxalatoborate was measured at different concentrations in the usual solvent mixture propylene carbonate (PC) / DME (1: 1) (FIG. 1).
- the measurement results show that at concentrations of up to 15% by weight, conductivities of up to 14 mS / cm are achieved (cf. FIG. 1). These values are at the same height or even above the conductivities that can be achieved with L ⁇ PF 6 .
- DMC dimethyl carbonate
- EC 11.0 mS / cm are achieved.
- Lithium bis (oxalatoborate) is readily soluble in water and in many polar aprotic solvents. In tetrahydrofuran (THF) 42 wt% and at 23 C C 30% Gew ⁇ chts- about dissolve at 50 ° C. In diethylene glycol dimethyl ether (diglyme) and mixtures of diglyme and Carbonates have a solubility of at least 15% by weight.
- THF tetrahydrofuran
- diglyme diethylene glycol dimethyl ether
- mixtures of diglyme and Carbonates have a solubility of at least 15% by weight.
- lithium bis (oxalatoborate) is completely stable up to about 300 ° C.
- the lithium bis (oxalatoborate) according to the invention can be prepared by reacting a lithium compound such as lithium hydroxide (anhydrous or the hydrate) or lithium carbonate or a lithium alkoxide with oxalic acid or an oxalate and a boron compound such as boron oxide or boric acid or a boric acid ester.
- a lithium compound such as lithium hydroxide (anhydrous or the hydrate) or lithium carbonate or a lithium alkoxide
- oxalic acid or an oxalate a lithium alkoxide
- boron compound such as boron oxide or boric acid or a boric acid ester.
- the reaction can, but need not necessarily, be carried out in a solvent.
- lithium hydroxide or lithium carbonate is reacted with a stoichiometric amount of oxalic acid and a stoichiometric amount of boric acid or boron oxide in water, e.g. :
- H 2 0 LiOH + 2 H 2 C 2 0 4 + H 3 B0 3 > Li [(C 2 0 4 ) 2 B] + 4 H 2 0
- reaction of lithium oxalate with oxalic acid and boric acid or boron oxide in water is also preferred, e.g .:
- H 2 0 Li 2 C 2 0 4 + 3 H 2 C 2 0 4 + 2 H 3 B0 3 > 2 Li [(C 2 0 4 ) 2 B] + 6 H 2 0
- Oxalic acid is preferably introduced in aqueous solution and the calculated amount of lithium base added, or lithium oxalate is mixed with 3 times the molar amount of oxalic acid. The calculated amount of boric acid or boron oxide is then added to this partially neutralized oxalic acid solution.
- the reaction temperature is in the range between 0 and 100 ° C.
- the mixture After the end of metering, the mixture is heated to 50 to 100 ° C. for some time and then the water is distilled off. When crystallization begins, the pressure is slowly reduced. The final drying takes place with stirring at approx. 50 to 150 ° C and ⁇ approx. 1 mbar.
- water is not necessarily added as a solvent.
- water is produced as a reaction by-product in different amounts.
- the starting materials are suspended in an organic solvent and the water released in the formation reaction is removed by azeotropic distillation. Suitable for this procedure are all solvents which are immiscible or only miscible with water
- Form water / solvent azeotrope and have such a high volatility that subsequent product drying is possible.
- the reaction starts spontaneously or is initiated by adding small amounts of water.
- the reaction temperature of the exothermic reaction is between 0 and 150 ° C.
- the reaction mixture is then heated to the boiling point, the water of crystal and reaction being removed by azeotropic distillation.
- Aromatics such as benzene, toluene, xylene and ethylbenzene are particularly suitable for carrying out the reaction and azeotropic dewatering. So z. B. when using toluene within a reaction time of about 2 to 4 hours the calculated amount of water.
- the product according to the invention separates in a finely crystalline, flowable form, completely water-free and in good purity. It is separated from the reaction solvent by filtration, washed with an aprotic solvent (for example toluene or more volatile hydrocarbons such as hexane or pentane) and dried in vacuo and / or at elevated temperatures (50 to 150 ° C.).
- an aprotic solvent for example toluene or more volatile hydrocarbons such as hexane or pentane
- water-miscible ethers such as. B. 2-methyltetrahydrofuran.
- the lithium bisoxalatoborate only forms in a contaminated form, i.e., it must then be cleaned relatively costly by fractional crystallization.
- a lithium alkoxide is mixed with a boric acid ester, the corresponding lithium tetraalkoxyborate Li [B (0R) 4 ] probably forming.
- This reaction does not need necessarily a solvent, but can be carried out in the presence of a solvent.
- the reaction mixture is then reacted with oxalic acid and the alcohol component released is removed by distillation. It is sensible to use boric acid esters for this variant which release volatile alcohols as possible, namely the methyl or ethyl compound:
- the alcohol itself ie methanol or ethanol
- an aprotic solvent such as acetonite
- the reaction temperature in this process variant is 0 to 100 ° C, the most sensible is the range between about 20 and 70 ° C.
- acetonitrile e.g. hexane, pentane , Diethyl ether
- aprotic solvent e.g. hexane, pentane , Diethyl ether
- L ⁇ B0 2 can be used at the same time as lithium and as boron compound together with oxalic acid to the desired.
- lithium bis (oxalatoborate) can also be prepared in aprotic media directly in a completely anhydrous form.
- lithium borohydride is reacted in a solvent according to the following reaction equation with two equivalents of anhydrous oxalic acid:
- the reaction is advantageously carried out in a solvent with which L ⁇ BH 4 has a certain solubility, for example in ethers, such as tetrahydrofuran (THF). Those solvents which are usually used by the battery industry for the production of electrolytes are also used particularly advantageously. Polyethers such as 1,2-dimethoxyethane are particularly suitable.
- the reaction temperature is not critical. At the bottom it is limited by the increasing viscosity as the temperature drops. On the other hand, it should not rise too high in order to avoid a possible reductive attack by the hydride on the oxalic acid or the lithium bis (oxalatoborate). In general, the temperature range between - 20 and 50 ° C is optimal. The course of the reaction can easily be followed by observing the evolution of gas.
- Example 1 Synthesis of Li [(C 2 0 4 ) 2 B] from lithium hydroxide, oxalic acid and boric acid in water with subsequent total evaporation ng
- Example 3 Synthesis of Li [(C 2 0 4 ) 2 B] from lithium hydroxide, oxalic acid and boron oxide in toluene with subsequent azeotropic water separation
- Example 4 Synthesis of Li [(C 2 0 4 ) 2 B] from lithium carbonate, oxalic acid and boric acid in 2-methyltetrahydrofuran (2-MeTHF) with subsequent azeotropic water separation
- the reaction mixture was refluxed 45 mm (66.6 ° C.) and, after cooling, decanted from an extremely finely divided white solid (the solid could not be separated off using a G 3 glass filter).
- the total evaporation of the clear decanted solution on a rotary evaporator gave 23.71 g of a greasy solid. Taking the decantation losses into account, this corresponds to 25.4 g - 101% of the theoretical yield. Small amounts of a colorless sublimate were observed in a rotary evaporator, which gave no 11 B NMR signal and dissolved water with an acidic reaction, which indicates oxalic acid.
