1. A solid polymer electrolyte based on the complex of polyethylene oxide with a salt of an alkali metal with the generalised formula poly(CH2CH2O)nMeX, where Me is Li+>, Na+> or K+>, and X is ClO4->, I->, BF4->, CF3SO3->, AsF6->, N(CF3SO2)2, and n is a natural number from 1 to 30 and stand for the molar ratio of oxyethylene units and the number of salt moles. It is characterised in that it is a mixture of the complex of polyethylene oxide with a salt of an alkali metal, and of carboxylic aluminium derivative with the formula (R1>)2AlR2>, where R1> is aliphatic radical C1-C5, R2> is a group with formula 1 in which R3> is aliphatic radical C1-C5, Y is the group -CH2CH2- or -CH=CH- or -CH2CH2CH2- or the group with formula 2, formula 3 or formula 4, and m is a positive integer. The mixture contains, in proportion to its weight, 0.1-90 percent by weight of a carboxylic aluminium derivative. 2. A method of producing a solid polymer electrolyte on the basis of the complex of polyethylene oxide with a salt of an alkali metal with the generalised formula poly(CH2CH2O)nMeX, where Me is Li+>, Na+> or K+>, and X is ClO4->, I->, BF4->, CF3SO3->, AsF6->, N(CF3SO2)2, and n is a natural number from 1 to 30 and stands for the molar ratio of oxyethylene units and the number of salt moles, whereby the solutions of the components are mixed in acetonitrile, the solution is poured over a flat surface and the solvent vaporises. It is characterised in that the component modifying the complex of polyethylene oxide with a salt of an alkali metal is the carboxylic aluminium derivative with the formula (R1>)2AlR2>, where R1> is aliphatic radical C1-C5, R2> is a group with formula 1 in which R3> is aliphatic radical C1-C5, Y is the group -CH2CH2- or -CH=CH- or -CH2CH2CH2- or the group with formula 2, formula 3 or formula 4, and m is a positive integer... |
