The first results of the deposition of coatings from accelerated ions of fluorinated fullerene C60(CF3)12 are presented. The coatings are formed at room temperature on Si substrates from a beam of singly charged C_60(CF_3)_12^ + ions with an energy of 5 keV, as well as from an ion beam that also contains doubly charged C_60(CF_3)_12^2 + ions and a certain amount of ionized fragments of molecules. The properties and structure of coatings obtained from accelerated ions of fluorinated fullerene are compared with the properties and structure of coatings obtained from accelerated fullerene C60 ions under the same conditions. According to X-ray photoelectron spectroscopy (XPS), fluorinated fullerene coatings contain about 4

In this work the optimum composition of anode material for all-solid-state batteries based on silver and solid electrolyte CsAg4I2.5Br2.5 was determined. For this, electronic conductivity of the mixture of the solid electrolyte and carbon black was studied. The percolation behavior of systems was studied. Percolation thresholds were determined for each system theoretically and experimentally. It was shown that the electrochemically accessible silver surface in the anode material has non-monotonic dependence on the silver content. As a consequence, the exchange current in the cell also has a maximum.

The carbon films formed by accelerated C60 ion deposition are investigated by transmission electron microscopy and X-ray photoelectron spectroscopy. It is demonstrated that amorphous carbon films are formed at an ion-beam energy of 7 keV and a temperature of the substrate of 100–200°C. Substrate temperature increase to 300°C results in the formation of nanocomposite films consisting of graphite nanocrystals embedded in an amorphous carbon matrix. The presence of double- and triple-charged C60 ions with an energy of 14 and 21 keV respectively in the beam results in a decrease in the temperature of formation of the nanocomposite to 200°C. As the result of analysis of the data collected from various sample depths by X-ray photoelectron spectroscopy and Auger-electron spectroscopy, it is found that the sp3/sp2 ratio in the surface layers is higher than in the sample bulk, both in the case of a monoenergetic 7 keV beam, and in the presence of multicharged high-energy ions in the beam. If high-energy ions are present in the beam, then the sp3/sp2 ratio is higher and depends, in a complex way, on the temperature of deposition. The maximum amount of sp3 bonds in the surface layers is found at a temperature of deposition of 350°C and is equal to 88%. The water drop contact angle for this film is 96°, which is similar to the contact angle of the diamond surface.

A technology for preparation of thin-film solid-state batteries based on the silver‑iodine electrochemical system by aerosol deposition in vacuum is developed. Functional layers of the battery are studied by optical and scanning electron microscopy. Voltammetric characteristics of the thus assembled battery show that its maximum discharge current exceeds 3 mA/cm 2 , which is sufficient for supplying power to the majority of medical devices.

The effect of tin(IV) oxide on the conductivity and chemical stability of sodium–silicate glass has been studied for five different glass compositions. Dilatometry and DSC were used to investigate the thermal behavior of the glass. The research into transport characteristics of the glass has shown that its conductivity is in the range of 2 × 10 –8 –5 × 10 –7 S/cm at 25°C and 10 –3 S/cm at 300°C.

The influence of yttrium oxide on the transport properties and chemical stability of sodium silicate glasses is investigated. The seven sodium-yttrium silicate glass compositions were synthesised. There are three composition with Na2O/Y2O3=6.5 and four with permanent Na2O content with 5 to 8mol% of Y2O3. The thermal behaviour of the glasses was studied with dilatometric and DSC methods. The research into the electrical characteristics of the glass has shown that their electrical conductivity is in the range of 5×10−8–10−6S/cm at 25°C and 10−3S/cm at 300°C. It is shown that the hydrolytic resistance increases when growing the Y2O3 concentration in the glass composition at constant Na2O content.

Sodium-Yttrium-Silicate glass composed of 35Na2O · 5.3Y2O3 · 59.7SiO2 and 37.9Na2O · 5.7Y2O3 · 56.4SiO2 and silicon—phosphorus glass composed of 37.9Na2O · 5.7Y2O3 · 51.4SiO2 · 5P2O5, which are similar in composition, have been synthesized. Thermal behavior of the above glass has been studied by the methods of dilatometry and DSC. The study of electrical characteristics of glass showed that their electrical conductivity is in the range 8 × 10−9−3 × 10−8 Sm/cm at 25°C, 5 × 10−4−10−3 siemens/cm at 300°C. The obtained values of the electrical conductivity are on the level of the best values known for sodium glassy solid electrolytes. It was found that the introduction of phosphorus oxide leads to a decrease in the conductivity of the glass.

New potassium-conducting solid electrolytes based on potassium monogallate in the K 2−2 x Ga 2− x V x O 4 system are synthesized and studied. It is found that an introduction of V 5+ ions leads to a considerable increase in the KGaO 2 conductivity due to the formation of vacancies in the potassium sublattice. The conductivity for optimal compositions is approximately 10 −3 S cm −1 at 400°C and above 10 −2 S cm −1 at 700°C. The results are compared with early obtained data for potassium monogallate dopped with four-charged cations.

New potassium-conducting solid electrolytes in the mixed ferrite-aluminate K1.80(Fe1 − x Al x )1.90V0.10O4 and K1.85(Fe1 − x Al x )1.925P0.075O4 are synthesized and studied. In the first system, the conductivity only slightly depends on the composition; therefore, the composition of solid electrolyte can be optimized with respect to the conductivity-stability characteristics. In the second system, extremes and considerable negative deviations from the additivity are observed in the conductivity isotherms. Possible reasons for this phenomenon are discussed.

New solid electrolytes with a high conductivity by K+ ions in the K1 − 2x Sr x GaO2 system are synthesized and studied. It is found that the introduction of Sr2+ ions into potassium monogallate leads to the formation of solid solutions with KGaO2 structure in a wide range of additive concentration. These solid solutions exhibit a high conductivity; the conductivity increases monotonically with increasing concentration of strontium within the single-phase range. The electrical characteristics are related to the electrolyte structure. The results are compared with the earlier data for the gallate solid electrolytes with the additives of four-charged cations and the systems based on potassium monoferrite and monoaluminate.

New potassium-monoaluminate-based solid electrolytes with high potassium-cationic conductance are synthesized, by partial substitution of penta-charged cations Nb5+ and Ta5+ for Al3+ cations, and studied. Both additives increased drastically the KAlO2 conductivity over the entire studied temperature range. The reason for the increase in the potassium monoaluminate conductivity, on the introducing of the studied additives, is the formation of potassium vacancies as a result of the substitution reaction Al3+ -> Nb5+ (Ta5+) + 2V'c, as well as broadening of the region of existence of the KAlO2 high-temperature gamma-modification whose transport properties exceed those of the low-temperature beta-form.

New high-conductivity solid electrolytes based on potassium monoaluminate and monoferrite are synthesized by partial substitution of V5+ for three-charged cations. In both systems, the introduction of vanadium cations leads to a substantial increase in the conductivity, with the maximum values corresponding to upper boundaries of the monophase solid solution regions. The principal factors responsible for the high conductivity are the formation of potassium vacancies at the substitutions M3+ → V5+ + 2V’ K and the extension of the temperature range of existence of high-temperature modifications of KAl(Fe)O2.
