Abstract / Full Text

LiFePO4 nanoparticles have been synthesized by a rapid microwave–solvothermal process at 200°C within 10 min. In spite of the low synthesis temperature, the as-synthesized powders with thinner thickness along [010] direction are highly crystalline. Sample exhibited excellent rate capability and showed good cyclic performance. The short reaction times of just 10 min show the basis for an efficient and time-saving synthesis of nanosized LiFePO4.
