Definitions
- the present invention relates to mixtures of borate or phosphate salts and polymers and their use in electrolytes, batteries, capacitors, supercapacitors and galvanic cells.
- Battery cells based on liquid electrolytes generally have relatively good ionic conductivities, but tend to leak, which then leads to the release of liquids that are potentially dangerous to humans and the environment. The production of such battery cells is also limited with regard to the possible sizes and shapes of these cells.
- Polymer electrolytes are usually based on an optionally crosslinked polymer and a conductive salt.
- conventional polymer electrolytes often show only low ionic conductivities, which do not meet the high demands placed on modern batteries.
- Gel or hybrid electrolytes are understood to mean electrolyte systems which, in addition to an optionally crosslinked polymer and a conducting salt, contain a solvent.
- the crosslinking of these polymers is often carried out at relatively high temperatures in the presence of the conductive salts.
- the corresponding conductive salts must therefore have a relatively high thermal solution
- REPLACEMENT BLA ⁇ (RULE 26) Have stability, since otherwise there is a risk of their decomposition and thus a reduction in the ionic conductivity of the resulting gel electrolyte.
- LiPF 6 Due to the low thermal stability, LiPF 6 , which has the greatest commercial distribution as a salt in liquid electrolytes, is not suitable for use in polymer or gel electrolytes. In addition, LiPF ⁇ is extremely sensitive to hydrolysis. Hydrofluoric acid HF can quickly develop in contact with moist air or with residual water from the solvents. In addition to its toxic properties, HF has a very negative effect on the cycle behavior and thus on the life and performance of the electrochemical cells.
- the aluminum usually used as a cathodic current arrester is not sufficiently passivated by imides (LA Dominey, Current State of Art on Lithium Battery Electrolyte in G. Pistoia (ed.) Lithium Batteries; New Materials, Development and Perspectives, Amsterdam, Elsevier, 1994 and literature cited therein).
- imides LA Dominey, Current State of Art on Lithium Battery Electrolyte in G. Pistoia (ed.) Lithium Batteries; New Materials, Development and Perspectives, Amsterdam, Elsevier, 1994 and literature cited therein.
- methanides can only be produced and purified with great effort.
- the electrochemical properties such as oxidation stability and passivation of aluminum depend very much on the purity of the methanide.
- EP 698 301 and WO 98/07729 disclose lithium spiroborates with aromatic ligands and their use as conductive salts in galvanic cells. The use of these salts as conductive salts in polymer electrolytes is not described.
- lithium bis (oxalato) borate and lithium tris (oxalato) phosphate describe two salts and their use as conductive salts.
- Polymer electrolytes based on these salts are also not disclosed here.
- the object of the invention was to provide electrolytes which do not have the disadvantages of the prior art. The task was therefore to provide electrolytes which, in addition to good ionic conductivity, also have high thermal stability.
- Another object of the present invention was to extend or improve the life and performance of batteries, capacitors, supercapacitors and galvanic cells.
- R 4 , R 5 , R 6 are the same, different or in pairs different, optionally directly connected to one another by a single or double bond and each have the individually or together

- the lithium bis [bis (trifluoromethyl) hydroxyacetato] borate polymer / gel electrolyte is prepared analogously to the second stage from Example 1.
- Step 1
- Lithium tris [bis (trifluoromethyl) hydroxyacetato] phosphate is synthesized analogously to lithium tris (oxalato) phosphate according to DE 199 33 898, with the difference that bis (trifluoromethyl) hydroxyacetic acid is used as the ligand instead of oxalic acid.
- the lithium tris [bis (trifluoromethyl) hydroxyacetato] phosphate polymer / gel electrolyte is produced analogously to the second stage from example 1.
