In order to attain a higher conductivity of phase Li₈ZrO_6, which has the relatively higher conductivity and chemical stability to lithium the effect of substitution of Zr-sublattice was investigated. The homogeneous region of the solid solutions Li₈Zr_{1 – x}Ce_xO₆ was 0 ? x < 0.07.

Using the method of electrochemical noise the processes proceeding on no polarized Li electrode in a stationary condition and during its polarization in different aprotic organic electrolytes are investigated. By the analysis of Li electrode noise characteristics it is confirmed, that electrochemical process at cathodic and anode polarization is localized under passivated film.

The article is about operating features of aluminium-water hydrogen microgenerators designed for use in portable power sources developed in GIHT RAS. Paper presents experimental data on the factors, which have an influence on hydrogen production rate, rate control ways and combined hydrogen microgenerator and air-hydrogen fuel cell stack testing in close to practical work conditions.

To increase structural stability under cycling, LiMn₂O₄ was modified by co-doping with 3d-metals (Co, Ni, Cr, Fe) and lithium. The synthesis of spinels was realized by preliminary mechanical activation of reagent mixture and subsequent heat treatment at 750°С.

The method of thermodynamic simulation was used to establish equilibrium products of chemical interactions in the systems lithium metal – solid electrolyte (SE). Calculations were performed at 25–165^o C for Li₆BeO₄, LiYO₂, LiScO₂, Li₅SiN₃, Li₈SiN₄, Li₃AlN₂, Li₂SO₄, Li₂ZrO₃, Li₄ZrO₄, Li₈ZrO₆ and Li₅AlO₄ solid electrolytes.

Some regularities of the structure formation of carbon-black-dispersed teflon gas diffusion layers of air (oxygen) electrodes of fuel cells and their initial components in process their making have been studied by the high-performance method called Dynamic Desorption Porometry and the BET (at the temperature of liquid nitrogen). The investigated input objects were Acetylene Gas detonation Black (AB) and Ketjen Black (KB). The pore size distribution of initial and hydrophobizated AB, KB and GDL on their base have been obtained.

A 350–400 V storage battery is necessary as a buffer or auxiliary battery for electrically driven car with fuel cell power plant developed at UEIP together with «AvtoVAZ». With this aim in view, the development of batteries with filter-press configuration based on nickel metal hydride system is of great interest.

Using graphs of voltage change on the battery charged with direct and asymmetric current and of corresponding discharges we find this mathematical descriptions, energy consumption for charging and quantity of energy for discharge are specified by integration; comparative characteristics of charge efficiency are specified.

Research results of accelerated forming of nickel-cadmium and battery cell by asymmetrical current are given. The comparative data on the forming by directive current are given. The chosen mode of forming by asymmetrical current has allowed to reduce cycle quantity and total molding time by factor of 3 at smaller rate of gas evolution and heat in comparison with the forming mode by directive current. Control of battery self-discharge confirmed preservation of required battery performances at forming by asymmetrical current.

Gel polymer electrolytes (GPE) based on polyester diacrylates and 1 M LiBF₄ in ? -butirolactone are synthesized and studied. Bulk conductivity has made (3.65 – 2.04)·10 ^{– 3} Ohm ^–1·cm ^{– 1} at room temperature for GPE with introduction 10 – 20 w/w. % polyester diacrylate. Temperature dependences of electrochemical properties of GPE in an interval from -17° up to +50°С are Studied. Electrochemical properties the GPE inserted in polypropylene separators of different kinds are investigated.
