Effect of Organic Additives on Electrochemical Processes Influencing Zn-Air Battery parameters
Smejkal, Jan ; Čech, Ondřej (referee) ; Chladil, Ladislav (advisor)
The diploma thesis is focused on the study of the influence of selected organic additives on the properties and morphology of zinc deposit on the negative electrode when used in zinc-air accumulators. Organic additives have been selected based on the study of literature and previously done experiments. The deposition was made on the tin plate electrodes in a solution of 6 mol/l KOH saturated with ZnO with added additives. All chosen additives were studied with a focus on the morphology of zinc deposit and with regard to their ability to suppress dendritic growth. Zinc morphology was studied by using a Tescan Vega 3 electron microscope and a Rigaku MiniFlex HR 600 X-ray diffractometer.

Effect Of Organic Additives On Electrochemi-Cal Processes Influencing Zinc-Air Battery Parameters
Smejkal, Jan
This work is focused on the study of influence of selected organic additives on the properties and morphology of zinc deposit on the negative electrode when used in zinc-air accumulators. The deposition was made on the tin plate electrodes in a solutions of 6 mol/l KOH saturated with ZnO with added additives (Abeson Na 50, Flavol KDA, Span 85, Lugalvan G35 and Triton X- 100). All chosen additives were studied with a focus on the morphology of zinc deposit, with regard to their ability to suppress dendritic growth and with focus on zinc corrosion. Changes in zinc morphology were studied by using a Tescan Vega 3 electron microscope and a Rigaku MiniFlex HR 600 X-ray diffractometer.

Organic Additives Controlling Zinc Deposition From Alkaline Solutions
Smejkal, Jan
This work is focused on the study of the effect of selected additives on zinc deposition in alkaline electrolyte for the purpose of using the additives in zinc based battery. Deposition was performed on tinplate in 6 mol/dm3 KOH solution saturated by ZnO and with the addition of organic additives (Slovasol 2520/2, Tween 20, CTAB and Lugalvan G35). All selected additives were examined with the focus on the morphology of zinc deposit and with respect to their ability of dendritic growth suppression. Zinc morphology was studied using an electron microscope and an Xray diffractometer.
