SYNTHESIS OF SILICON NANOPARTICLES MODIFIED POLYESTER AS MATERIAL ACTIVE ELECTRODE ON A SECONDARY CELL BATTERY

Abstract

After oxygen, silicon is the second most prevalent element. Despite their abundance, this element is not discovered by itself. Minerals like silicates and aluminum silicates are typically where you can find silicon compounds. This study uses synthesis composite organic-inorganic hybrid resin with a silicon nanoparticles intermediate. Silicon nanoparticles modified polyester can be used as an anode electrode on a secondary cell battery. The characterization XRD of SiNPs showed silicon but contained other impurities such as SiO2, Mg, and MgO. The characterization XRD of SiNPs-PE showed silicon, and a broad peak indicated polyester. The surface area shows SiNPs 70.550 m2/g and SiNPs-PE 1.064 m2/g. Pore size showed SiNPs 0.892 nm and SiNPs-PE 1.683 nm. Pore volume showed that SiNPs 0.142 cm3/g and SiNPs-PE 0.002 cm3/g. The characterization SEM shows a spherical shape for silicon and a solid surface that shows polyester. The electrical conductivity of SiNPs is 2140,673 µS/cm and resistance 4,671 Ω at 1 V, while the electrical conductivity of SiNPs-PE is 2752,294 µS/cm and resistance 3,633 Ω at 1 V.
