| 總結: | © 2014, Journal of Ceramic Processing Research. All Rights Reserved. Silica/copper (SiO2/Cu) composites were prepared in nano-dimensions for use as anode materials in lithium-ion batteries. Modified Stöber and microwave-assisted methods were used to prepare of SiO2 and Cu, respectively. The composites were prepared with different tetraethyl orthosilicate (TEOS) concentrations and mole ratios of TEOS to Cu2+ reactants. Cu was observed as the main phase in the products, which agglomerated into large particles, with some of them dispersed on the SiO2 particles. SiO2 appeared in the composites was amorphous phase and spherical in shape. Decreasing the TEOS concentration decreased the size of the SiO2. |
