SLM-processed MoS 2 /Mo 2 S 3 nanocomposite for energy conversion/storage applications.

MoS 2 -based nanocomposites have been widely processed by a variety of conventional and 3D printing techniques. In this study, selective laser melting (SLM) has for the first time successfully been employed to tune the crystallographic structure of bulk MoS 2 to a 2H/1T phase and to distribute Mo 2 S 3 nanoparticles in-situ in MoS 2 /Mo 2 S 3 nanocomposites used in electrochemical energy conversion/storage systems (EECSS). The remarkable results promote further research on and elucidate the applicability of laser-based powder bed processing of 2D nanomaterials for a wide range of functional structures within, e.g., EECSS, aerospace, and possibly high-temperature solid-state EECSS even in space.
