Abstract Scope |
Selective laser sintering is an additive manufacturing technique that consists of using a laser to consolidate powdered material to create complex three dimensional parts. Typically, SLS utilizes thermoplastic polymer media to create dense plastic components (direct SLS). It is also possible, however, to use composite powders with non-melting additives paired with a suitable binder to create highly functional materials (indirect SLS). This paper will describe the creation of composite materials using conductive and electroactive material additives to create lithium-ion battery components (i.e. anodes, cathodes, separators, and cases). Selective laser sintering adds to the geometric flexibility of the lithium battery components and enables batteries that conform to their surroundings, effectively reducing their footprint. Preliminary galvanostatic charge/discharge and capacity numbers will be presented for the functional Li-ion half cells created using SLS, as well as next steps to improve capacity and reliability. |
