Method for synthesizing silicon-carbon composite using liquid type plasma, and silicon-carbon composite synthesized therefrom

摘要

The present invention relates to a method for synthesizing a silicon-carbon composite using a liquid plasma and a silicon-carbon composite synthesized therefrom, and more particularly, to a silicon nanoparticle rather than a silicon carbide compound through a liquid plasma. The present invention relates to a method for synthesizing a silicon-carbon composite using liquid plasma to enable simultaneous synthesis of silicon and carbon by forming a silicon-carbon composite in which silicon nanoparticles are uniformly distributed in a matrix, and a silicon-carbon composite synthesized therefrom. . The present invention includes a first step of preparing a solution in which a silicon precursor and a carbon precursor are mixed; A second step of disposing a pair of metal wires in the solution; A bipolar pulsed direct current power is applied to a pair of metal wires to form silicon nanoparticles from a solution through plasma discharge, and a silicon-carbon complex in which silicon nanoparticles are distributed in a carbon matrix. A method for synthesizing a silicon-carbon composite using liquid plasma, comprising a third step, and a silicon-carbon composite synthesized therefrom, as a technical summary.
