At present development of new effective methods for energy storage and conversion is an important problem for scientists. Thus, very important problem is research and progress of low cost, readily acceptable, long life, high energy storage or other type devices. Solid polymer electrolytes are materials, that can use as ion conductors in above mantion devices. They are separator in Li-ion polymer system, where litium ions move from anode to cathode during rechearge or discharge. They are interesting solid materials because ions ability to pass trough in it as in fluids. For purpose to research solid polymer electrolyte in lithium battary we have synthesized oligomers by tradition obtaining methods. In addition was conducted: 1)Synthesis of initial monomer type organocyclotetrasiloxanes with same or different attached groups via hydrosilylation reactions of 2.4.6.8-tetrahydro-2.4.6.8-tetramethylcyclotetrasiloxane with containing electron donor oxygen groups 2) Polymerization and co-polymerization reactions of obtained cyclic compounds. The electrophysical properties of the obtained polyelectrolytes were investigated by standard methods.
