Beschreibung
Zusammenfassung:	A process for producing spherical lithium iron phosphate/Carbon (LFP/C) or Lithium Iron Phosphorous Oxide/Carbon (LFPO/C) composite cathode material using a spray drying method to have carbon-coating materials coated on LFP or LFPO, particularly the LFP/C or LFPO/C composite cathode material provided with 3-dimensional (3D) spherical and porous structure can not only significantly improve conductivity of those active materials of LFP or LFPO, but also markedly solve the low electronic conductivity problem of the LFP material or the LFPO material, as well as improve the obtained LFP/C or LFPO/C exhibited excellent in high power characteristics and having very good cycling charge/discharge performances, and suited for making as a secondary lithium ion battery cathode.
