Production and characterization of nano silver oxide for silver zinc batteries

Yurtseven, Özüm Öyküm
Rechargeable silver-zinc batteries have aroused interest and find various area of usage depending on their notably technical advantages over other battery systems including their high specific energy and high recharge efficiency. In this battery chemistry, silver oxide and metallic zinc are used as the positive and negative active materials respectively. Chemically stabilized particles with large surface areas are needed to reach high discharge rates for battery applications. The use of nanoparticles as electrode materials has made a significant improvement in battery performance due to their enhanced electrical and chemical properties. In current study, we have successfully synthesized AgO nanoparticles through a sonochemical route. Parametric study was performed to examine the effect of reaction parameters such as reaction time, reaction temperature, and surfactant concentration on the quality of products. Synthesized AgO powder was characterized by particle size analyzer, X-ray diffraction (XRD), and scanning electron microscope (SEM). The AgO content of the prepared powder was 100 % and powder particle size mainly distribute in the range of 100-300 nm.


Development and characterization of tungstates and molybdates for li-ion batteries
Kaygusuz, Burçin; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2016)
In recent years, the need for portable power, lithium ion batteries dominate the markets because of their advantages. Metal tungstates and molybdates (Metals: Fe, Ni, Co, Mn, Zn, Mg) are two important families of inorganic materials and have found many applications in various fields, such as catalysis, magnetic applications, humidity sensors, and photoluminescence. However, their use in energy storage applications is almost none. The tungstates and molybdates adapt monoclinic crystal structure and crystalli...
Development and characterization of tin based anode materials for Li-Ion batteries
Yılmaz, Emre; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2018)
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 ...

Galioğlu, Sezin; Akata Kurç, Burcu; Department of Micro and Nanotechnology (2010)
Different kinds of nanoparticles are widely used in optoelectronic and photovoltaic applications to harvest light to increase efficiency of devices. ETS-10, which is a synthetic microporous material consisting of –Ti-O-Ti-O-Ti- wires that run in the crystal in a and b directions, has been of interest in such applications due to its unique properties. In the current study, the synthesis conditions of ETS-10 were investigated in order to obtain pure ETS-10 crystals with the desired morphology. For this purpos...

Sarwar, Saira; Karamat, Shumaila; Saleem Bhatti, Arshad; Aydınol, Mehmet Kadri; Oral, Ahmet; Hassan, Muhammad Umair (2021-10-16)
High energy storage capacity and longer life span make rechargeable Li-ion batteries the first choice in portable electronics. Here, a graphene-MoS2 composite material is investigated as a potential electrode material which enhances the electrochemical storage ability of the Li-ion batteries (LIBs). Graphene-MoS2 composite is synthesized from graphene oxide (GO), molybdenum trioxide and thiourea via hydrothermal route. Formation of graphene-MoS2 composite (molar ratio 1:2) is confirmed by X-ray diffraction ...

Muğan, Orkun; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2012)
Ni - MH batteries have superior properties which are long cycle life, low maintenance, high power, light weight, good thermal performance and configurable design. Hydrogen storage alloys play a dominant role in power service life of a Ni - MH battery and determining the electrochemical properties of the battery. LaNi5, belonging to the CaCu5 crystal structure type, satisfy many of the properties. The most important property of LaNi5 is fast hydrogen kinetics. Recently, CaNi5, belonging to same crystal type,...
