Abstract
An olivine structured nano-composite LiMxMn1−xPO4/C was synthesized by a sol-gel assisted high energy ball mill method and the synthesis method does not require any inert atmosphere. Electrochemical cycling studies were carried out between 3.0-4.6V using 1M LiPF6 in 1:1 EC/DEC as electrolyte. The charge/discharge cycling studies of the nano-composite exhibit an average discharge capacity of 158 mAh/g at 0.1 C rate over the investigated 50 cycles.
