- Аннотация: This review is devoted to different types of novel polymer electrolytes for lithium powersources developed during the last decade. In the first part, the compositions and conductivity ofvarious polymer electrolytes are considered. The second part contains NMR applications to theion transport mechanism. Polymer electrolytes prevail over liquid electrolytes because of theirexploitation safety and wider working temperature ranges. The gel electrolytes are mainly attractive.The systems based on polyethylene oxide, poly(vinylidene fluoride-co-hexafluoropropylene),poly(ethylene glycol) diacrylate, etc., modified by nanoparticle (TiO2, SiO2, etc.) additives and ionicliquids are considered in detail. NMR techniques such as high-resolution NMR, solid-state NMR,magic angle spinning (MAS) NMR, NMR relaxation, and pulsed-field gradient NMR applications arediscussed. 1H, 7Li, and 19F NMR methods applied to polymer electrolytes are considered. Primaryattention is given to the revelation of the ion transport mechanism. A nanochannel structure, compositionsof ion complexes, and mobilities of cations and anions studied by NMR, quantum-chemical,and ionic conductivity methods are discussed.
