Composites based on electrochemically active components, LiFePO4, LiMn2O4 and LiNi0.82Co0.18O2, for the use as cathode materials for lithium-ion batteries were synthesized using ultrasonic treatment. The effects of the sonication mode (series LiFePO4–LiMn2O4) and component ratio (series LiFePO4–LiNi0.82Co0.18O2) on the electrochemical performance of the resulting composites were studied. The obtained composites were examined by scanning electron microscopy and powder X-ray diffraction and tested in coin-type cells with lithium anode. Positive electrodes based on the obtained composites showed enhanced electrochemical performance.
