Chemistry and electrochemistry of composite LiFePO4 materials for secondary lithium batteries

In this paper, we report some practical data concerning the electrochemical behaviour of composite lithium iron phosphates, at higher rates of charge–discharge, at lower operating temperatures and during long cycle life tests. These results were collected on composite LiFePO4 powders (whose submicrometer particles were coated by carbon or boron-based wraps), all obtained from optimized syntheses using mechanochemical activation of an iron (II) precursor as main starting material.
