Cr and V Substitution in the LiMn(2)O(4)Spinel Positive Electrode Li-Ion Batteries

A. Akbulut; Çetinkaya, Tuğrul; M. O. Guler; Uysal, Mehmet; Akbulut, Hatem (POLISH ACAD SCIENCES INST PHYSICS, 2015)

In this study, LiCr0.2V0.4Mn1.4O4 cathode active electrode materials were produced via a facile sol-gel method at 800 degrees C. The surfaces of the LiCr0.2V0.4Mn1.4O4 cathode active electrode materials were then coated ...
Evaluation of Li-Air Batteries With EC-DEC Based Nanocomposite Electrolytes

A. Akbulut; M. O. Guler; Çetinkaya, Tuğrul; Uysal, Mehmet; Akbulut, Hatem (POLISH ACAD SCIENCES INST PHYSICS, 2015)

Electrolytes based on organic carbonate solvents of ethylene carbonate (EC) and diethyl carbonate (DEC) were prepared by using LiPF6 as the Li-source. Nano sized Al2O3 (50 nm) was used as a reinforcing component in order ...
Sol-Gel Synthesis of Nanocomposite Cu-Li4Ti5O12 Structures for Ultrahigh Rate Li-Ion Batteries

A. Erdas; Özcan, Serdar; M. O. Guler; Akbulut, Hatem (POLISH ACAD SCIENCES INST PHYSICS, 2015)

In this study, spinel Li4Ti5O12 materials were successfully synthesized by a simple and facile sol-gel process and electroless copper deposition techniques. The characteristics of the as-prepared Li4Ti5O12 and Cu-Li4Ti5O12 ...
The Electrochemical Properties of Cu Coated LiCr0.2V0.2Mn0.6O2 Nanocomposites for High Rate Li-Ion Batteries

Algül, Hasan; A. Erdas; Tokur, Mahmud; M. O. Guler; Akbulut, Hatem; Alp, Ahmet (POLISH ACAD SCIENCES INST PHYSICS, 2015)

Several reported problems of commercial LiCoO2 electrode materials such as high cost, toxicity, limited rate capability and safety concerns are still remain to be problematic to develop the lithium ion consumer electronics ...
