我们尝试了激光烧结硅片切割过程中的废硅粉和碳纳米纤维的混合物。通过硅和碳纳米纤维的强结合，成功地产生了具有高孔隙率的厚膜。厚膜的表面孔隙率和硅的结晶度可以通过改变激光束的扫描速度来控制。这些发现表明了未来锂离子电池硅阳极新制造方法的可行性。
We attempted the laser sintering of a mixture of waste silicon powder from silicon wafer slicing processes and carbon nanofibers. Thick films with high porosity were successfully generated by a strong combination of silicon and carbon nanofibers. The surface porosity of the thick films and the crystallinity of silicon were controllable by varying the scanning speed of the laser beam. These findings indicate the feasibility of a new fabrication method for silicon anodes for future lithium-ion batteries.
