Synthesis and properties of cathode material, lithiated iron phosphate, for lithium-ion batteries
Abstract
Possibilities of changing the electrochemical properties of a cathode material (LiFePO4) by changing methods and conditions for its synthesis are shown. The optimal methods for the preparation of the nanocomposite LiFePO4 with conducting carbon (mechanical mixture of ingredients or coating on LiFePO4 grains) and ways of improving the reversibility of the electrode process (peaks on cyclic voltammograms 3,3/3,5 V) and cathode cycling stability, achieving good charge characteristics (up to 150 mAh/g) by doping LiFePO4/C composite with transition metal (Mn, Cr, Ni, Zn) cations and Cl– anions are discussed.
