Definitions
- the invention relates to a new use for polyfluoropolyethers and their mixtures, and mixtures which contain one or more polyfluoropolyethers as flame-retardant solvents for electrolytes in rechargeable batteries.
- Alkyl acetates, substituted acetamides, sulfoxides, nitriles, glycol ethers and ethers are also suitable (EP-A 0 385 724).
- Rechargeable lithium batteries must meet a high level of safety, since critical operating conditions such as overcharging, over-discharging or short-circuiting, which can lead to the cell opening under fire, must be avoided.
- Suitable low-viscosity compounds are e.g. B. 1, 2-dimethoxyethane or linear alkyl carbonates such as dimethyl carbonate, ethyl methyl carbonate and diethyl carbonate.
- the object of the present invention is to provide a solvent mixture for conductive salts, with which the safety of the electrolyte solutions and the batteries filled with them is increased.
- polyfluorinated polyethers of the formula I are used.
- the invention thus relates to an electrolyte system for increasing the safety of rechargeable batteries, in particular lithium batteries, which contains compounds of the formula I in an effective amount of 1 to 80% by volume, preferably 20 to 60% by volume, in particular 40 to 60% by volume .-%, based on the total volume of the electrolyte system contains.
- Compounds of the formula I in which X is H or F, m and n are a number from 0 to 3 are preferred.
- polyfluoropolyethers of the formula I mentioned can be used as a single substance in combination with other solvents or as a mixture of ethers in combination with other solvents for the preparation of the electrolyte solutions.
- Lithium salts are preferably used as conductive salts.
- the conductive salts are usually present in the solvent in a concentration of at least 0.5 mol / l. Lead salt concentrations of about 1 mol / l are aimed for. The saturation concentration indicates the upper limit of the conductive salt concentration.
