Development and characterization of catalyst materials of zinc-air batteries
Arslan Hamat, Burcu; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2021-2-12)
Recently, primary and secondary zinc-air batteries have attracted considerable attention due to their high energy density, safety, availability and low cost. Zinc-air batteries generate electricity through a redox reaction between zinc and oxygen in air. Zinc-air batteries have higher theoretical energy density due to abundant supply of oxygen from the atmosphere. However, poor efficiency of the oxygen reduction (ORR) and evolution reactions(OER)taking place at the cathode limits the use of zinc-ai...

Li-ion batteries are the most popular type of portable secondary batteries. They generate electrons at anode electrode during discharging process by releasing $Li^+$ ions from anode, in which graphite is used as Li reservoir. Recently, $SiO_2$ and Tin (IV) Oxide materials are investigated as anode materials by researchers, due to their very high theoretical capacity. There are two problems, however, limiting their use which are pulverization and irreversible reaction problems. These problems are, also, the ...

Development and characterization of high power density cathode materials for lithium-ion batteries
Doğu, Şafak; Aydınol, Mehmet Kadri; Evis, Zafer; Department of Micro and Nanotechnology (2015)
In this thesis, facile and cost efficient aqua based synthesis method is developed to synthesize power dense and fast rechargeable LiFePO4 cathode materials. In order to obtain nano sized crystal morphology, nucleation controlled techniques were studied on precursor synthesis. These techniques are freeze (cryogenic) drying with co-precipitation and ultrasound assisted sub-sequential precipitation with vacuum drying at low temperatures (<350 K). In co-precipitation with freeze drying synthesis, star-like pla...
Development and characterization of high energy cathode materials for lithium-ion batteries
Büyükburç, Atıl; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2013)
The aim of this thesis is to produce high energy cathode materials based on LiCoO2 materials with the general formula LiCo1-xMxO2 and LiCo1-y-xMxNyO2. In order to achieve this formula, less exploited doping elements such as Mo, Cr and W will be used as well as Mn. During the study, the parameters of the processes which are solution preparation, freeze drying and calcination are optimized. According to the results, 24 hours of freeze drying is enough for drying the samples. Calcination at lower (< 700°C) tem...
