Abstract : This invention relates to battery electrolytes and more particularly to solid polymeric electrolytes. It is an object of invention to provide polymeric electrolytes using a wider variety of metal salts. These and other objects of this invention are accomplished by providing; A solid polymer electrolyte comprising: a) a matrix of linear poly(ethyleneimine) having the formula (-CH2CH2NH-)n;and b) a metal salt which is LiI, LiC1O4, NaI, NaBr, KI, CsSCN, AgNO3, CuC12, CoC12, Mg(C1O4)2, wherein the salt is dissolved in and distributed throughout the poly (ethylene imine) matrix and from more than zero to 0.10 moles of salt are used per mole of monomer repeat unit, (-CH2CH2NH)-). The poly(ethylene imine) used in the composites of this invention is linear and semicrystalline in nature.
