“…The main direction of investigations is lithium cation surroundings, local and macroscopic mobilities of Li + and F − -containing fragments, and electrolyte composition-ion transport correlations. Modern and complicated NMR techniques are employed, especially solid-state high resolution magic angle spinning (MAS) NMR, pulsed-field gradient NMR, and NMR spin relaxation [13,29,[32][33][34]37,39,40,42,47,[49][50][51][52][53][54][56][57][58][59][60][61]65,72,73,76,77,80,92,.…”

This review is devoted to different types of novel polymer electrolytes for lithium power sources developed during the last decade. In the first part, the compositions and conductivity of various polymer electrolytes are considered. The second part contains NMR applications to the ion transport mechanism. Polymer electrolytes prevail over liquid electrolytes because of their exploitation 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 ionic liquids 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 are discussed. 1H, 7Li, and 19F NMR methods applied to polymer electrolytes are considered. Primary attention is given to the revelation of the ion transport mechanism. A nanochannel structure, compositions of ion complexes, and mobilities of cations and anions studied by NMR, quantum-chemical, and ionic conductivity methods are discussed.

“…This study showed that the incorporation of TiO 2 NPs to the GPE improved its electrochemical stability and ionic conductivity in LIBs. Yamolenko et al [ 89 ] extended this study on the effect of NPs to a polyester-diacrylate (PEDAC)-based network polymer electrolyte. The mechanical strength of the GPE was enhanced after improving the distribution of the NPs in the polymer electrolyte by ultrasonic treatment compared to simple mechanical stirring.…”

Among the various types of polymer electrolytes, gel polymer electrolytes have been considered as promising electrolytes for high-performance lithium and non-lithium batteries. The introduction of inorganic fillers into the polymer-salt system of gel polymer electrolytes has emerged as an effective strategy to achieve high ionic conductivity and excellent interfacial contact with the electrode. In this review, the detailed roles of inorganic fillers in composite gel polymer electrolytes are presented based on their physical and electrochemical properties in lithium and non-lithium polymer batteries. First, we summarize the historical developments of gel polymer electrolytes. Then, a list of detailed fillers applied in gel polymer electrolytes is presented. Possible mechanisms of conductivity enhancement by the addition of inorganic fillers are discussed for each inorganic filler. Subsequently, inorganic filler/polymer composite electrolytes studied for use in various battery systems, including Li-, Na-, Mg-, and Zn-ion batteries, are discussed. Finally, the future perspectives and requirements of the current composite gel polymer electrolyte technologies are highlighted.

The 1 butyl 3 methylimidazolium tetrafluoroborate-propylene carbonate-ethylene carbonate system in a reticular polymer electrolyte based on polyethylene glycol diacrylate and LiBF 4 was studied by high resolution and pulsed field gradient NMR. The 1 H, 13 C, 7 Li, and 19 F NMR spectra of the electrolyte systems were analyzed. During the electrolyte synthesis, propylene undergoes structural changes in the ionic liquid, which adversely affects the ion conductivity (the maximum conductivity in this system is 8.46 × 10 -4 S/cm at 20°C) and the self diffusion coefficients of the lithium ions. When the propylene car bonate content in the polymer electrolyte increased from 15 to 32 wt %, the proportion of lithium ions with a high self diffusion coefficient (10 -11 m 2 /s) decreased from 24 to 7%. In the case of ethylene carbonate, this effect was less pronounced, the conductivity in these systems reaching 2.46 × 10 -3 S/cm at 20°C. The high resolution NMR study did not reveal any structural changes in the ionic liquid and ethylene carbonate during the modeling of radical polymerization.
