Structural modelling of the process of self-discharging in alkaline accumulators

A structural model of the alkaline accumulator that takes into account self-discharging is suggested from which all the well-known empirical dependences were obtained. It was shown that the existing empirical dependences describing the process of self-discharging in alkaline accumulators don't contradict one another but supplement each other as they are true, each in its interval of discharging time.

Usage of fuel elements in house building

Problems of using fuel cells as both electric and heat energy sources are reviewed. Such "hybrid" fuel cells possess enhanced net efficiency up to 90%. Some examples of fuel cells sets use in dwelling from small cottages up to multi-storey hotels are presented.

The analysis and visual results of the thermal runaway of the tight nickel-cadmium accumulators НКБН-25-УЗ

Having analyzed the energy balance of the thermal runaway it was shown that the thermal runaway is not due to an external source of current but due to powerful internal self-accelerating exothermal reaction. And this reaction takes place in quite accidental spots of the electrode starting from a point and spreading radially like in the process of burning.

Our experience on the design and application of power sources for remote-area power-supply systems

Our experience of the design and application of power sources based on various electrochemical systems for surface and rocket-borne power systems of modern and promising rocket-space vehicles, submarine vehicles, electronic hardware, and other objects with high specific requirements to power sources is presented.

Modern status of mechanically-recharged air-aluminum power sources of high reduced energy

In the paper are presented results of studies and design of air-aluminum chemical power sources carried out jointly by Moscow Aircraft Institute and AltEn Corp.; several fields of effective application of these power sources are listed, a technological scheme of reaction product utilization and waste electrolyte regeneration is shown.

Application of the methods of volumetric electric-spark dispersion for the fabrication Ti-Zr-Ni hydrogen storage alloy

Results of X-ray and electrochemical analyses of properties of the Ti-Zr-Ni powders obtained by the volumetric electric-spark dispersion method in water, alcohol, kerosene, liquid nitrogen and liquid argon are represented. An influence of the working liquids and parameters of discharge pulses on the chemical composition, phase-structural state, electrochemical characteristics and electrical capacity of the obtained powders are considered.

Anode non-carbon lithium-accumulating composite materials

It is a review of foreign periodical literature on perspective anode materials for lithium-ion and lithium-polymer batteries. The submitted data concern mainly to the period 1998-2003 The published data on lithium-accumulating composites alternative to traditional carbon systems are analyzed. Merits and demerits of electrodes made of tin oxides, tin, antimony, copper and iron intermetallides. as well as boron-, nitrogen- and silicon – containing anode materials are discussed

Utilization of aluminum in low-temperature chemical power sources

The state-of art of primary and secondary batteries with aluminum negative electrode, including aluminum-oxygen (air) batteries as well as batteries with positive electrodes based on various other oxidizers is considered.

Near tasks of the International Technical Committee 044 and standardization problems in the branch
