Lead-acid batteries of hybrid vehicles (HEV) are working in a particial state of charge (PSoC). The negative electrode of batteries have low capacity of electric charge reception. Their lifetime is dependent on the rate of development of lead sulfate PbSO4 on the negative electrode...

The topics of this article are NiZn accumulators, their usage, advantages and disadvantages. It also discusses the goals of further research focused on this type of accumulators and some problems which have to be solved.

The paper presents the initial results of research aimed to developing of prototypes of solar air collectors made mostly from recycled plastic. In research conducted by the Centre of Renewable Energy in Košice were analyzed and subsequently selected the suitable materials for various&#x...

This work deals with the improvement of the production based cathode material LiCoO2 pro for lithium-ion batteries, using the method of deposition of the solid phase. The main objective is to achieve a capacity that would be as close as possible theoretical value 155 mAh/...

Action of energy systems without failures, are dependent on energy reserves. In the article are shown examples of reservoirs, of biological, technical or social functional units. For renewable energy systems, designed for remote area systems without connection to the grid, are also cruc...

This paper deals with topic of pulse charging regimes for accumulators. It summarizes advantages and disadvantages of such regimes in the way they are presented in recent journals. In the more practical part of the paper an experiment with old lead-acid accumulator that was no...
