“…An emerald phase base an can be conductive by doping with an acid. Protonations are added to the -N= region (EB form) while the number of electrons in the chain remains [3]. Intrinsically conductive polymer material Polyaniline (PANI) has unique electrical properties because it can be an insulator or conductor where the conductivity values range from 10 -9 to 10 -2 S/cm [4].…”

Fumaric acid doped polyaniline was confirmed by FTIR as a sample of polyaniline emeraldine salt phase. This study aims to determine the value of the electrical conductivity of PANi/PVA with variations in distance. The electrospinning method was carried out on a PANi/PVA solution to form polyaniline nanofibers. The electrospinning solution used a percent ratio of 1:1 PANi/PVA (10%) with variations in the distance of the nozzle to the collector, namely 13 cm, 15 cm, and 17 cm. The morphological characterization and fiber properties obtained from electrospinning were characterized using FTIR, optical microscopy, and SEM-EDX. The number of fibers decreases and becomes finer as the distance increases. Fiber decreased in number due to evaporation of PVA. The diameter comparisons obtained from PANi/PVA fiber and pure PVA fiber are 263 nm and 240 nm. So the PANi/PVA fiber diameter is slightly larger than that of the PVA fiber. Electrical conductivity was carried out using the four-point probe method. The electrical conductivity value from the measurement of the best PANi/PVA sample is 1.39 × 10-6 S/cm at a distance of 15 cm with the best fiber shape.

Lithium iron phosphate (LiFePO4) based material is one of the most prospective candidates as a cathode material in lithium-ion batteries because of its lower cost, safer, and environmental benignity compared to lithium cobalt oxide (LiCoO2), which is commonly used for lithium-ion batteries manufacturing. However, its low conductivity is the obstacle of this material to solve, so that modification with the addition of silicon (Si) is expected to improve the electrochemical performance. Meanwhile, solid state reaction is considered simple and effective in LiFePO4 crystal growth process. Therefore, Si-doped LiFePO4 using solid state reaction in this research aims to study its structure and morphology as well as the effect of adding Si to its conductivity. The synthesis began with mixing LiH2PO4, Fe2O3, carbon black, and six-mole ratio variation of Si to LiFePO4 using agate with ethanol: acetone addition then dried in an oven at 80°C and heated at 550°C in a furnace for 6 hours under argon atmosphere and sintering temperature of 870°C for 16 hours with the same condition. The sample of 3% mole ratio performed the highest conductivity of all variations with 3.01 x 10-6 S.cm-1, and was identified as Li0.93Fe1.07P0.93O4Si0.7 with orthorhombic structure, Pnma space group (Ref. Code: ICSD 98-016-1792) with the highest peak at 2θ = 35.556° from XRD analysis with rectangular-like shape particle.
