A facile synthesis of zinc oxide/multiwalled carbon nanotube nanocomposite lithium ion battery anodes by sol-gel method

Köse, Hilal; Dombaycıoğlu, Şeyma; Aydın, Ali Osman; Akbulut, Hatem (ELSEVIER SCIENCE BV, 2015)

Free standing zinc oxide (ZnO) and multiwalled carbon nanotube (MWCNT) nanocomposite materials are prepared by a sol gel technique giving a new high capacity anode material for lithium ion batteries. Freestanding ZnO/MWCNT ...
Production and characterization of free-standing ZnO/SnO2/MWCNT ternary nanocomposite Li-ion battery anode

Köse, Hilal; Dombaycıoğlu, Şeyma; Aydın, Ali Osman; Akbulut, Hatem (PERGAMON-ELSEVIER SCIENCE LTD, 2016)

High capacity ZnO/SnO2/MWCNT ternary nanocomposite films were prepared as free-standing anode materials by sol-gel spin coating method to increase the electrochemical discharge capacity of the Li-ion battery electrodes. ...
Reduced graphene oxide supported tin oxide-boron oxide flexible paper anodes for Li-ion batteries

Köse, Hilal; Dombaycıoğlu, Şeyma; Akbulut, Hatem; Aydın, Ali Osman (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2019)

Freestanding tin oxide-boron oxide/reduced graphene oxide (SnO2-B2O3/rGO) nanocomposite anode was produced for Li-ion cells. This binder-free flexible paper anode structure was fabricated by combining SnO2-B2O3 composite ...
Sol-Gel Synthesis of Nanostructured SnO2 Thin Film Anodes for Li-Ion Batteries

Köse, Hilal; Aydın, Ali Osman; Akbulut, Hatem (POLISH ACAD SCIENCES INST PHYSICS, 2012)

Sol-gel technique was employed to prepare semiconductor tin dioxide (SnO2) thin films. Comparatively, it gives an advantage over other techniques by its low reaction temperature, easy process and low cost. The effect of ...
Structural properties of size-controlled SnO2 nanopowders produced by sol-gel method

Köse, Hilal; Dombaycıoğlu, Şeyma; Aydın, Ali Osman; Akbulut, Hatem (ELSEVIER SCI LTD, 2015)

SnO2 nanoparticles were synthesized by sol-gel method with different sol concentrations and the effect of sol concentration on the structural properties of SnO2 was investigated. The aim of this work is synthesizing of ...
The effect of LiBF4 concentration on the discharge and stability of LiMn2O4 half cell Li ion batteries

Dombaycıoğlu, Şeyma; Köse, Hilal; Aydın, Ali Osman; Akbulut, Hatem (ELSEVIER SCI LTD, 2015)

Electrolytes were prepared with different LiBF4 salt concentrations in the ratio of 2:1 (w/w) Ethylene Carbonate (EC): Dimethyl Carbonate (DMC) solvents. Different LiBF4 concentrations were used in the electrolytes to ...
The effect of LiBF4 salt concentration in EC-DMC based electrolyte on the stability of nanostructured LiMn2O4 cathode

Dombaycıoğlu, Şeyma; Köse, Hilal; Aydın, Ali Osman; Akbulut, Hatem (PERGAMON-ELSEVIER SCIENCE LTD, 2016)

Electrolytes which have different LiBF4 salt concentrations (0.8 m, 1.0 m, 1.2 m and 1.4 m) in the ratio of 2:1 (w/w) Ethylene Carbonate (EC): Dimethyl Carbonate (DMC) solvents were prepared. Obtained electrolytes were ...
