Abstract
Cathodic Capacity Promotion Via Narrow Range of Nano-Te(IV)-Dopings on LiMn2-xTexO4 -Spinel
Khaled M.Elsabawy, Waheed F. El-Hawary and A.El.Maghraby
Samples with general formula LiMn2-xTexO4 ( where x= 0.025,0.05 mole ) were successfully synthesized through thermal decomposition of LiMnC2O4 (OAc) precursor,.The structural , micro-structural and electrochemical features of pure spinel and tellurium doped samples were investigated . The electrochemical investigations included cyclic voltammetry, charge– discharge cycling of coin model cells were performed. Capacity retentions ( loss with recycleability for first twenty nine cycles) were promoted with tellurium doping recording maximum for x = 0.025 mole ( 0.31 % loss per cycle ) and 0.93 % loss per cycle for LiMn1.95Te0.05O4 and minimum one for the undoped parent LiMn2O4
