摘要：
In the present paper, samples of pure and doped lithium iron phosphate composite with the following composition: LiFePO4/C, Li0.99Fe0.98(CrNi)(0.01)PO4/C were synthesized. The samples were synthesized using the sol-gel method. According to the acquired data, all the obtained samples of lithium iron phosphate are crystallized in the orthorhombic modification of lithium iron phosphate with the structure of olivine. The average particle size of the obtained materials varies in the range of 50-100 nm. The carbon content was 4 wt%. The doping of lithium iron phosphate with trivalent cations of chromium and nickel results in the increase of the discharge capacity at high discharge rates with the simultaneous stability augmentation during the cycling.
