Abstract: 

The aerosol pyrolysis method was used to synthesize lithium-iron-phosphate (LiFePO4), a cathode material for lithium-ion batteries. LiFePO4 was synthesized from lithium carbonate, obtained from Kazakhstan spodumene, raw material. Modifying additives as the electrically conductive polymer polyaniline improve battery cycling.

Keywords:
