Selective laser sintering (SLS) is an additive manufacturing (3D printing) technique that can be applied to the anode of lithium batteries to simplify the manufacturing process and enhance the production efficiency. The specific surface nanostructures and intermetallic compounds (IMC) induced by the SLS process can improve the capacity and cycle life. In this study, a stable anode for a lithium ion battery was successfully fabricated by the SLS process, the capacity of the battery exceeded 150 mAhg-1 after 10 cycles under a 0.1 C current rate at room temperature. Moreover, the capacity enhanced to 250 mAhg-1 after 10 cycles under a 0.1 C current rate at the high temperature of 55°C. The results show the potential of the SLS technique for application in the lithium ion battery industry.
