Abstract:<\/h4>\n
3D printing of energy storage systems is at the heart of In-Space Manufacturing strategy. Within this context, Li-ion polymer batteries printing through Fused Filament Fabrication (FFF) is envisaged. This study is devoted to optimising the extruded solid polymer electrolyte filament properties. As the poly(ethylene oxide) (PEO) \u2013 lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) electrolyte offers the best Li+ conductivities but suffers from poor mechanical behaviour, poly(propylene) (PP) is added to ensure filament printability. An exhaustive investigation highlights the impact of the PEO molar weight and the LiTFSI and PP proportions. Fine-tuning these parameters alters molten phase viscosity, which affects the electrolyte morphology and ionic conductivity. Best formulations feature a co-continuous structure that provides effective mechanical reinforcement and exhibits the best ionic conductivity reported so far for an FFF-printed solvent-free polymer electrolyte of 1.2 \u00d7 10\u22124 S.cm\u22121 at 70\u00b0C. Therefore, it opens the way towards polymer battery printing, on the Earth and in microgravity conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"
