Zinc based negative electrode for alkaline accumulators
Prchal, Jiří ; Svoboda, Vít (referee) ; Špičák, Petr (advisor)
The object of this project is research and preparation of the permanent zinc electrode in a strong alkaline surrounding for the usage in Ni-Zn accumulators. This system is characterized by a low overall ecological impact on environment, higher specific energy and higher electromotive force than nowadays commonly used systems (lead, nickel-cadmium). The goal of this project is to originate a new procedure, which will make possible to steady a zinc electrode. Every research faces a problem shaping changes of zinc electrode during cycling and related low cycle life. This work consists of the theoretical part, in which is explained a basic accumulators mechanism and practical part, in which is described performed research.
