POROUS SILICON CARBON COMPOSITE, METHOD FOR MANUFACTURING SAME, AND NEGATIVE ELECTRODE ACTIVE

The invention provides a porous silicon-carbon composite material, a manufacturing method thereof and a negative electrode active material comprising the same. Since the porous silicon-carbon composite material contains silicon particles, magnesium fluoride and carbon, the initial efficiency, the capacity retention ratio and the discharge capacity of the secondary battery can be further improved. 本发明提供了一种多孔硅碳复合材料、其制造方法以及包含其的负极活性材料。由于本发明的多孔硅碳复合材料包含硅颗粒、氟化镁和碳，二次电池的初始效率和容量保持率以及放电容量可以进一步提高。
