    • A brief review of layered rock salt cathode materials for lithium ion batteries 

      Tan, Tze Qing; Soo, Soon Peng; Azmi, Rahmat, Prof.; Shamsul Baharin,  Jamaludin, Prof. Dr.; Rozana Aina, Maulat Osman, Dr. ; Zul Azhar, Zahid Jamal, Dato Prof. Dr.; Mohd Sobri, Idris, Dr. (Trans Tech Publications, 2013)
      Nowadays, many researchers have been studying on the layered rock salt-type structure as cathode materials for the lithium ion batteries. LiCoO2 is the most commonly used cathode material but Co is costly and toxic. Thus, ...

    • Determination of interlayer mixing and oxygen non-stoichiometry in LiNi0.8Mn0.1Co0.1O2-δ using powder diffraction data 

      Mohd Sobri, Idris, Dr.; Rozana Aina, Maulat Osman, Dr.  (Trans Tech Publications, 2013)
      The effect of preparation conditions, temperature and atmosphere, on oxygen stoichiometry and interlayer cation mixing in the layered rock salt material LiNi0.8Mn0.1Co0.1O2-δ has been investigated using X-Ray powder ...

    • Electrical properties of fresnoite Ba2TiSi2O8 using impedance spectroscopy 

      Rozana Aina, Maulat Osman, Dr. ; Mohd Sobri, Idris, Dr. (Trans Tech Publications, 2013)
      Fresnoite with composition Ba2TiSi2O8 (B2TS2) was first found in 1965, adopting a non-centrosymmetric structure. It also reported to crystallize in a tetragonal unit cell with a=8.52Å and c=5.210Å leading to some possible ...
