Electronic tester of capacity and internal resistance of batteries and accumulators
Machala, Pavel ; Kubánek, David (referee) ; Lattenberg, Ivo (advisor)
This work deals with the design and realization of electronic tester of capacity and internal resistance of galvanic cells. In the begining is situated the familiarization with basic concepts and features of galvanic cells. There are also described appropriate methods for measuring capacity and internal resistance. These principles are aplied into the design of electronic tester which is described in detail in the next chapter. The designed device is controlled by a microprocessor chip ATmega16, whose software is thoroughly described in the second part. In the end you can find the results of testing and assessment of these tests.

Electrochemical properties of negative electrode made from natural and expanded graphite
Priščák, Juraj ; Máca, Josef (referee) ; Libich, Jiří (advisor)
This bachelor thesis deals with lithium-ion accumulators from the prespective of its structure, operation and using. It studies anode materials, focusing on natural and expanded graphite. Explains operation and structure of lithium-ion accumulator. The second part of thesis aims on manufacturing of anode electrodes of natural and expanded graphite. Deals with their measurement of its current a capacity rating. The aim of the thesis is how characteristic of accumulator depends on features of anode materials. In conclusion is sum up and comparation both materials on base of their measurement.
