摘要
We examine Li4Ti5O12 (LTO) anode component inserted into PES produced by pulsed laser ablation in liquid media method with adjustable its particle size by tuning laser repetition rate, followed by post irradiation, to investigate the capability for using in Rechargeable lithium-ion batteries applications. Thermal analysis illustrates how material characteristics change with temperature. X-ray diffraction (XRD), Fourier transform infrared (FT-IR), and energy dispersive spectra (EDS) are used to assess the compound's phase composition, optical characteristics, and elemental analyses. Without any usual peaks for other impurities, notably rutile and anatase TiO2, the XRD pattern showed a cubic spinel structure with high crystallinity of just LTO structure. The sample's component elements are confirmed by the EDS spectra since only the peaks for the impurities Ti and O could be seen in the spectra. FT-IR revealed that the broad absorption bands appeared at wave numbers in the figure print region because of the stretching vibrations of the octahedral groups (MO6) lattice. The XPS survey spectra reveal the presence of Li, Ti, O, C, and S. TGA revealed that the interaction of hydroxyl groups of PES with functional groups of LTO via hydrogen bonding may result in a temperature shift of breakdown. Electrical conductivity measurements were conducted at various frequencies and temperatures. The generated samples' real and imaginary parts of dielectric parameter characteristics were tested at frequencies ranging from 0.1 to 3 M Hz and temperatures ranging from 200 to 500 K. The temperature variation of the real component of the dielectric constant indicates that these compounds have high electromagnetic absorption and wideband electrical activity.
