Study of LiFePO4 electrode morphology for Li-Ion battery performance

Abstract

The paper focuses on the development of lithium-ion battery cathode based on lithium iron phosphate (LiFePO4). Li-ion battery cathodes were manufactured using the new Battery R&D Production Line from ROM-EST Centre, the first and only facility in Romania, capable of fabricating the industry standard 18650 lithium-ion cells, customized pouch cells and CR2032 cells. The cathode configuration contains acetylene black (AB), LiFePO4, polyvinylidene fluoride (PVdF) as binder and N-Methyl-2-pyrrolidone (NMP) as solvent. X-ray diffraction measurements and SEM-EDS analysis were conducted to obtain structural and morphological information for the as-prepared electrodes.
