Abstract
A composite electrolyte (151). The composite electrolyte (151) including a binder, a solvent, a non-solvent, and a ceramic filler. The non-solvent is configured to cause the binder to self-interact. The composite electrolyte (151) may be cast (138) or printed (144).
Claims7
A composite electrolyte comprising:
- a binder comprising 20 wt % to 50 wt % of a total weight of the composite electrolyte, the binder being selected from the group consisting of PVDF, PVDF-HFP, PTFE, PEO, PMMA, PAN, CNC, SBR, and combinations thereof;
- and
- a ceramic filler comprising 50 wt % to 80 wt % of the total weight of the composite electrolyte, the ceramic filler having a cross-sectional diameter ranging from 50 nm to 150 nm and being selected from the group consisting of Al2O3, SiO2, TiO2, MgO, Li2O, LiAlO2, BaTiO3, LAGP, LATP, LLTO, and combinations thereof,
- wherein the composite electrolyte has a porosity greater than 50% comprising a plurality of submicron pores.
