Definitions
- the invention relates to electrolytes for lithium ion batteries.
- Lithium hexafluorophosphate is used as the conductive salt in many commercial lithium ion batteries. This salt has all the necessary properties for use in such batteries, in particular it is characterized by good solubility in aprotic solvents, combined with a comparatively high ionic conductivity of its solutions.
- lithium hexafluorophosphate when used alone as a conductive salt, also has serious disadvantages, in particular the poor thermal stability and the pronounced tendency to hydrolysis in the presence of traces of water, which include the formation of hydrofluoric acid, HF and phosphorus oxytrifluoride, POF 3 .
- DE 19829030 C1 discloses a conductive salt, namely lithium bis (oxalato) borate, which has excellent electrochemical stability having.
- the inherent advantage of this salt is that it can be made and used without any use of halogens and halogenated compounds, especially fluorine and its compounds.
- a disadvantage of using lithium bis (oxalato) borate and other lithium chelatoborates is, however, that their solutions in binary solvent mixtures often have lower ionic conductivities than comparable solutions of other conductive salts, in particular lithium hexafluorophosphate.
- a 0.6 molar solution of lithium bis (oxalato) borate in ethylene carbonate / dimethyl carbonate (EC / DMC) 1: 1 has a conductivity of 7 mS / cm, a 1.0 molar solution of LiPF 6 in the same solvent in contrast, a conductivity of 11 mS / cm.
- concentration of lithium bis (oxalato) borate in binary solvent mixtures based on organic carbonates is limited. Often only a maximum concentration of 0.7 to 0.8 mol / l lithium bis (oxaiato) borate can be achieved in these solvent mixtures.
- the electrolyte used is also intended to guarantee the functioning of the battery in the widest possible temperature range, especially at extremely low temperatures.
- the previously described solution of lithium bis (oxalato) borate in EC / DMC solidifies at temperatures ⁇ -15 ° C and then has conductivities of about 10 to 100 ⁇ S / cm, which are not sufficient for operating a battery at conventional current densities are.
- EP 0980108 A1 describes quaternary mixtures of ethylene carbonate, dimethyl carbonate, diethyl carbonate and ethyl methyl carbonate, a process for their preparation and the use of such mixtures for the production of electrolytes based on LiAsF 6 with improved temperature properties. If a similar quaternary mixture is used to produce an electrolyte using lithium bis (oxalato) borate as the conductive salt, the conductivity improves at low temperatures (-20 ° C), but the conductivity drops to 5.5 mS at room temperature /cm.
- the ionic conductivity of the electrolyte has a direct effect on the energy and power density of a galvanic element filled with such electrolytes.
- the amount of charge that can be removed under a higher current load drops as a result of an electrolyte's conductivity being too low.
- One way to reduce the disadvantage of the electrolytes produced on the basis of lithium bis (oxalato) borate in terms of their high current carrying capacity is to use larger electrode areas in the corresponding batteries in order in this way to obtain the desired amounts of charge at lower current densities can.
- the disadvantages of such a solution would be the too large volume and the too large mass of such a battery; this also against the background that the batteries e.g. to be used in portable devices with small overall weights.

It must also be ensured that there is always a sufficient concentration of lithium ions at the interfaces between the electrolyte and electrodes.
