Investigation size effect of negative active mass additive on service life lead-acid accumulator.
Mikoláš, Jiří ; Novák, Vítězslav (referee) ; Bača, Petr (advisor)
The task of research work is to study new mechanisms and to minimize disturbance of lead batteries for hybrid electric vehicles. Those arising under the PSoC (Partial State of Charge) and is linked to irreversible sulphation mainly negative electrodes. As one solution to prevent sulphation of the negative electrode appears to be the active ingredients in a negative matter. In the investigated electrodes is verified the influence of carbon, titanium dioxide and silica on the grain size of the order of nanometers.

Improving of use properties of lead-acid accumulator
Szabó, Jaroslav ; Tonar, Karel (referee) ; Abraham, Pavel (advisor)
Lead-acid accumulators are the oldest and most common type of secondary cells. There are still some problems to solve. Grid corrosion in sulphuric acid is one of them, which reduced lifetime of lead-acid accumulators. The first part of work is focusing on a general theoretic description of lead – acid accumulators. Following is a description of the workstation and method of measuring. The final part of the text is measuring on an experimental cell.

Using lead-acid accumulators in hybrid electric vehicle regime
Klojda, Viktor ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
This bachelor´s thesis is focused on utilization of maintenance-free lead-acid accumulators in hybrid electric vehicle regime. It describes paralel and serial draft of hybrid vehicles, their function, advantages and disadvantages. It compares lead-acid accumulators with other sorts of primary, secondary and fuel cells. Purpose of this thesis is to improve the lifetime of lead-acid batteries in PSOC regime and accompanying addition use, as an activ material of negative electrode.

The cycle modes of lead-acid batteries
Mičák, Tomáš ; Tošer, Pavel (referee) ; Vaculík, Sebastian (advisor)
Main goal of the diploma thesis is to examine lead-acid accumulator and to study cycling modes in different setups. Theoretical part describes history, types of maintenance-free batteries, degradation mechanisms and possibilities to remove them. Practical part involves the production of electrodes and experimental cell, composition of active mass and measurement of internal resistance. Different configurations for deep cycling are researched as well. The results of the work are summarized and commented at the conclusion of the thesis.

Effect of additives in lead-acid batteries for hybrid electric vehicles
Tobolák, Jakub ; Křivík, Petr (referee) ; Bača, Petr (advisor)
This thesis is focused on lead-acid batteries used in hybrid electric vehicles. These batteries operate under partial charge, which brings problems with premature capacity loss. Tasks is to examine the influence of glass fibers as possible additives to the negative electrode of these cells in order to extend their life. The text describes the problem of hybrid electric vehicles, lead-acid batteries and other electrochemical sources.
