Abstract

Silicon dioxide has been produced by deposition from an aqueous solution of Na2SiО3 · mH2O. The particle size of the main faction of the synthesized material determined using an electron microscope ranges from 12 to 16 nm. According to XRD phase analysis, an amorphous modification of silicon dioxide has been obtained. It was then used to synthesize a thin-layer SiO2/Ni composite via electrolysis to determine the possibility of using it in the negative electrodes of miniature LIBs (LIBs). Studies of the SiO2/Ni composite in a prototyping lithium-ion battery in the galvanostatic mode have shown stable cycling in the voltage range from 0.40 to 0.15 V indicating promising usage in LIBs.
