TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The electrolyte salt is formed by combination of: a cation comprising lithium, sodium and potassium with an anion comprising hexaperflurate, tetrafluoroborate, chloride, bromide, iodine, perchlorate, hexafluoroarsenate, methyl carbonate, trifluoromethane sulfonate, lithium bis(trifluoromethane sulfonyl and fluorinated sulfonamide.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The first acrylate compound is tetraethyleneglycol diacrylate, polyethyleneglycol diacrylate (molecular weight 50-20000), bisphenol A ethoxylated diacrylate (molecular weight 100-10000), 1,4-butanediol diacrylate and 1,6-hexanediol diacrylate. The second acrylate compound is trimethylolpropane triacrylate, trimethylolpropane ethyoxylate triacrylate, trimethylolpropane propoxylate triacrylate, ditrimethylolpropane tetraacrylate, pentaerythritol tetraacrylate, pentaerythritol ethoxylate tetraacrylate, dipentaerythritol pentaacrylate, dipentaerythritol hexaacrylate and tris(2-(acryloyloxy)ethyl)isocyanurate. The first acrylate compound and the second acrylate compound are used in: (I) (0.01-10-wt.%) and in a weight ratio of 1:10-10:1 (first acrylate compound: second acrylate compound). The organic solvent is at least one solvent comprising cyclic carbonates, linear carbonates, lactones, ethers, esters, sulfoxides, acetonitriles, lactarns, ketones and their halogen derivatives. EXAMPLE - A solution of lithium perfluoronamide (1M) was dissolved into an organic solvent contained ethylene carbonate (EC), propylene carbonate (PC)and diethyl carbonate (DEC) in a ratio of 2:1:7 (v:v:v, EC:PC:DEC). Tetraethyleneglycol diacrylate (0.8 wt.%) having two acryl groups of formula acrylic acid 2-(2-(2-(2-acryloyloxy-ethoxy)-ethoxy)-ethoxy)-ethyl ester and trimethylolpropane triacrylate (0.2 wt%) having three acryl groups of formula acrylic acid 2,2-bis-acryloyloxymethyl-butyl ester were added to the solution as additives to give electrolyte.
