摘要：

A method of obtaining a solid polymer electrolyte for lithium-ion batteries based on polyethylene oxide-containing (PEO) supramolecularly organized system segmented polyurethane - segmented oligourethane with LiClO4(PUU-OUU-LiClO4) is proposed. The introduction of LiClO4 into PUU-OUU leads to an extreme increase in the glass transition temperature and ionic conductivity by 1 and 2 orders of magnitude when compared to OUU-LiClO4 and PUU-LiClO4 systems (up to 2.0 center dot 10(-4) S/cm at 60 degrees C), respectively, which is associated with a change in the lithium-ion transport mechanism.
