During work execution, influence of the composition of polymer electrolyte on the thermal stability was determined. Causes of the thermal destruction of polymer electrolytes , influence of the nature of polymer matrix and plasticizer on polymer electrolyte conductivity have been studied The ways of the electrochemical parameter optimization of the system electrode - polymer nonaqueous electrolyte have been determined. By the methods of thermogravimetric analysis, IR-spectroscopy, electrode impedance thermal stability, conductivity of the synthesized polymer electrolytes based on CPVC and PVdF have been determined. New polymer electrolytes based on copolymer polyvinylidene fluoride and hexafluoropropylene of organic and siliconorganic ethers of polyethylene glycols. On the basis of the synthesized polymer electrolytes the cells of the system Li-MnO2 with discharge voltage 3.0 have been manufactured, their tests at the continuous cycling mode at ambient temperature and at 400 С have been carried out. Application - electrochemical industry. Product Description popup.authors popup.nrat_date 2020-04-02 Close
