PAni-coated LiFePO4 Synthesized by a Low Temperature Solvothermal Method

Abstract: The composite LiFePO 4 /polyaniline was prepared by chemical synthesis to promote the intensification of the electrochemical properties for use as cathodes in lithium ion batteries. The X-ray diffraction (XRD) of LiFePO 4 synthesized by solvothermal method were indexed to the orthorhombic structure, according to the JCPDS 40-1499. The spectra Raman and FTIR showed a high degree of ordering of LiFePO 4 with interaction between LiFePO 4 surface with structure conjugate of conducting polymers. The cyclic voltammo… Show more

“…They attributed it to the electrochemically active PANI additives. Recently, Fagundes and coworkers [92] reported a PANI/LFP composite cathode material for LIBs. The composite was fabricated via an alternative synthesis route, which was beneficial to enhanced electrochemical properties and fast electron transfer rate of the LPF.…”

“…All these characteristics makes this nanocomposite a promising material for several applications such as energy storage, capacitors, sensors, solar cells, fuel cells and so on [12,14,15]. Capacitors are devices widely used in power electronics applications, i.e., they are submitted to high thermal stress and electrical voltages [16]. Moreover, in other applications, aging acts on the stability of transport properties, being extremely important for charges conduction in polymeric materials.…”
