The mock-up of nickel-metal hydride storage battery of filter-press type with rated voltage of 6 V and capacity of 1.7 A·h is assembled and tested. The capability of storage battery operation with bipolar nickel-metal hydride electrodes in a single case with common gas collector is demonstrated, and the problems, consideration of which will enable to enter on a battery prototype stage, are defined.

The probability of the thermal runaway in nickel-cadmium accumulators with lamellar electrodes has been studied experimentally. It has been shown that in electrodes of these accumulators that have long terms of service there is a great amount of hydrogen just as in the accumulators with metal-ceramic and striking electrodes. However, the thermal runaway in nickel-cadmium accumulators with lamellar electrodes is less probable than in the accumulators with metal-ceramic and striking electrodes.

Herein are considered some ways to improve the performance efficiency of sealed batteries of high capacity by providing uniform electrolyte distribution with battery height, increasing active mass utilization coefficient and limiting PCL effect.

The method of a rotating disk electrode leads studying the basic laws of electrochemical behaviour of mediator as basic electroactive component of bioelectrochemical system and influence of speed of rotation of an electrode, concentration of mediator, glucose and microbial cells are certain for the general speed of process bioelectrocatalitic oxidation of glucose.

The influence of the concentration of antimony, tin, cadmium, calcium, silver, and barium on some characteristics of lead-antimony and lead-calcium alloys was studied. The cadmium-doped and barium-doped alloys show the best corrosion resistance among the lead-antimony and lead-calcium alloys, respectively.

Effect of high-collated carbon clusters (soots containing fullerenes and nanopipes) on electrode pastes structure have been studied and their positive effect on characteristics of the obtained active masses has been shown. Effect of partial hydrophobization of negative active mass (NAM) on efficiency of the closed oxygen cycle has been studied. Effect of different additives (С₇H₆O₂, C₈H₈O₂, (-CF₃-CF₂₅-)QZ) on ?_H2 have been studied.

The concept of processing of the positive electrode material taken from fulfilled alkaline accumulators, based on primary separation of an iron component from nickel at stages of hydrometallurgical repartition, is presented..

This paper represents performance of air-hydrogen free-breathing Fuel Cell (FC) in limited volume conditions. Research work was carried out with thin two-cell stacks related to use in prototype of particular power source system, which includes aluminium-water microgenerator of hydrogen. In small current densities field (<200 mA/cm²) it was established, that after FC had been confined within the small volume, characteristics of FC became better than in non-limited-volume conditions due to self humidification.

Reversible lithium intercalation from a non-aqueous electrolyte into thin films of tin (0.1–1 mcm) and carbon (-3 mcm) was studied by means of electrode impedance spectroscopy. The measurements were made within a frequency range of 10⁵–10^-2 Hz at a varying lithium concentration in the matrix. The paper discusses several versions of electrical equivalent circuits to simulate the experimental impedance spectra, and the concentration dependence of the lithium diffusion coefficient.

The production of pasted electrodes has been analysed. The equation which connects paste rheology, porous matrix and technologic parameters has been obtained. The approach optimises pasted electrode technology.
