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.

Selective Leaching of LiFePO4 by H2SO4 in the Presence of NaClO3

“…Methods of spent LiFePO4 battery disposal include the cascade utilisation and recovery of valuable metals [1,2]. Cascade utilisation aims to ensure the quality and safety of target products but is only applied in some demonstration plants, as the performance of waste batteries is unpredictable [3].…”

Overcoming Practical Barriers in Reconditioning Li-Polymer Batteries

“…Among secondary batteries, a special interest is granted to lithium batteries (lithium-ion and lithium-polymer batteries) due to their high energy density and long lifetime. Lithium-polymer batteries tend to be more frequently used as they may be adapted to various forms required for electronic devices, are safer compared to lithium-ion batteries and have high energy density and high values of C-Rate [1][2][3][4][5][6].…”
