Electrochemical Characteristics of Different Li2FeSiO4 Polymorphs

摘要: Li2FeSiO4 has been lately considered as an alternative cathode material for large scale Li-ion batteries due to its promising properties such abundance of raw materials and stability during the operation [1-10]. The major drawbacks, like very low intrinsic conductivity difficulty preparation pure samples, have recently overcome by specific synthesis techniques producing phase-pure with optimal morphologies [3,4]. Furthermore, employing appropriate techniques, based composites can give good electrochemical activity even at moderate current densities (moderate power densities).
