Solid-state and flexible zinc carbon (or Leclanche) batteries are fabricated using a combination of functional nanostructured materials for optimum performance. Flexible carbon nanofiber mats obtained by electrospinning are used as a current collector and cathode support for the batteries. The cathode layer consists of manganese oxide particles combined with single-walled carbon nanotubes for improved conductivity. A polyethylene oxide layer containing titanium oxide nanoparticles forms the electrolyte layer, and a thin zinc foil is used as the anode. The battery is shown to retain its performance under mechanically stressed conditions. The results show that the above configuration can achieve solid-state mechanical flexibility and increased shelf life with little sacrifice in performance.


Polystyrene-based and carbon fabrİc-reİnforced polymer composİtes containing carbon nanotubes: preparation,modification and characterization
Erkmen, Berrak; Bayram, Göknur; Department of Chemical Engineering (2020-11-23)
Carbon Fabric-Reinforced Polymers (CFRPs) attract attention due to their high mechanical properties, electrical conductivity, and providing weight reduction solutions in aerospace, automotive, marine, and energy industries. Since recycling, long processing times, non-visible damages, and complex repair procedures of thermoset-based CFRPs cause problems, studies are performed on the application of thermoplastic-based CFRPs. This study aims to produce polystyrene (PS)-based and carbon nanotubes (CNTs) and car...
Epoxy-based composites and coatings: improvement of multifunctional properties
Çaldıklıoğlu, Almira; Bayram, Göknur; Department of Chemical Engineering (2019)
The purposes of this study are to improve mechanical properties, thermal stability, resistance to flammability, electrical conductivity and hydrophobicity of epoxy (E) by incorporation of expanded graphite (EG) and titanium dioxide (T) particles. In this study, sonication with the use of solvent method was primarily determined for the epoxy-based binary composite and coating preparation. By this method, the epoxy composites and coatings were produced by changing EG concentration as 0.05, 0.1, 0.25, 0.5, 0.7...
Flexible supercapacitor electrodes with vertically aligned carbon nanotubes grown on aluminum foils
Dogru, Itir Bakis; Durukan, Mete Batuhan; Turel, Onur; Ünalan, Hüsnü Emrah (2016-06-01)
In this work, vertically aligned carbon nanotubes (VACNTs) grown on aluminum foils were used as flexible supercapacitor electrodes. Aluminum foils were used as readily available, cheap and conductive substrates, and VACNTs were grown directly on these foils through chemical vapor deposition (CVD) method. Solution based ultrasonic spray pyrolysis (USP) method was used for the deposition of the CNT catalyst. Direct growth of VACNTs on aluminum foils ruled out both the internal resistance of the supercapacitor...
Carbon coating of magnesium particles
Aktekin, Burak; Eyovge, Cavit; Öztürk, Tayfur (2017-10-05)
Magnesium when hydrided has low thermal and electrical conductivity and carbon coating would be useful to remedy this for a variety of purposes. In this study, carbon coating was achieved by co-feeding magnesium and methane into a thermal plasma reactor. This yielded carbonaceous material with magnesium particles 5-10 nm in size embedded in graphitic matrix. A further reduction down to 2-3 nm was possible but required reductions in the precursor feed rate. 2 wt% carbon was sufficient to fully protect magnes...
Novel structured electrolytes for solid oxide fuel cells
TİMURKUTLUK, BORA; Celik, Selahattin; Timurkutluk, Cigdem; Mat, Mahmut D.; Kaplan, Yuksel (2012-09-01)
Novel grate type electrolytes are designed and fabricated to improve the cell performance and to lower the operation temperature of intermediate temperature electrolyte supported solid oxide fuel cells based on scandium and ceria stabilized zirconia by partly reducing the electrolyte thickness. The characteristics of three different small size cells (11.62 cm(2) active area) having various electrolyte designs are investigated. A standard electrolyte supported cell is also produced as a base case for compari...
