| Abstract Scope |
In the field of lithium-ion batteries, traditional polymer-based separators are typically vulnerable to mechanical puncture, and dendrite penetration. In contrast, 3D-solid separators are fabricated with interconnected porous architectures. This study employs high-modulus materials (lithium hexafluorophosphate (LiPF6)) and tailored polymer pore-structures to facilitate higher charge/discharge rates and enable stable cycling over extended periods. Their compatibility with next-generation high-voltage cathodes and lithium metal anodes further positions 3D-solid separators as a crucial enabler for the development of ultra-high-energy-density and longer-lifespan Li-ion batteries. The solid, thermally stable network improves thermal runaway resistance under high-temperature. EIS and mechanical property characterization were done, and the results show a decrease in compression strength of 64.2% compared to PLA of 100% infill but with an improved ionic conductive of 2.529x10-5 S/cm. The process proved to improve ion exchange at the electrode-electrolyte interface, reduce material waste, and cost, and fully recyclable design parts that could be printed in space. |
