3D printing of hybrid MoS2-graphene aerogels as highly porous electrode materials for sodium ion battery anodes

This study reports a 3D freeze-printing method that integrates inkjet printing and freeze casting to control both the microstructure and macroporosity via formation of ice microcrystals during printing. A viscous aqueous ink consisting of a molecular MoS2 precursor (ammonium thiomolybdate) mixed …
