摘要：

The electrochemical performances of the two polymorphs of Li3Fe2(PO4)(3) are reported. We show that reversible capacities as high as 110 mA h g(-1) at C/20 regime with an excellent capacity retention are obtained by playing with particle sizes and surface. Tailored made particles were done chemically, by developing a new low temperature synthetic route. In contrast, the modification of the particle surface was achieved by ball-milling of carbon/Li3Fe2(PO4)(3) mixtures, confirming again the positive attribute of such process regarding the electrochemical performances of transition metal phosphates.
