1. A complex Si—C cathode base units, comprising:
a first order Si—C nanoparticle including a plurality of graphene pieces, and a plurality of complex monomers formed by nanometer scale silicide, and first high molecular material; the first high molecular material is used as viscosity for combining the plurality of graphene pieces and the plurality of complex monomers, a plurality of buffer spaces are formed between the plurality of graphene pieces, the complex monomers and the first high molecular material;
a second high molecular material layer enclosing the first order SiC nanoparticle; the second high molecular material layer being calcined in a calcination process, so that the carbohydrate therein is carbonized; and
a plurality of nanometer carbon tubes tightly enclosing the second high molecular material layer so that the first order Si—C nanoparticle is difficult to expand; wherein the nanometer carbon tubes have lengths between 15˜25 μm and are arranged as an array.
