| Abstract Scope |
Conformal solid-state batteries (CSSB) facilitate utilization of various energy storage systems in electric vehicles due to enhanced durability/flexibility. Designing ceramic-polymer composite electrolyte is essential to develop CSSB due to synergistic effect of increased conductivity and high flexibility of composite electrolyte. Also, Na-ion batteries are seen to be potential alternatives to conventional Li-ion batteries owing to abundance and low cost of sodium compounds. Present work focuses on developing a novel NZSP-based ceramic electrolyte with co-doping of Mg and Sc with different concentrations and implementing the best suitable material to fabricate polymer-ceramic composite electrolyte. The composite containing 20wt% polymers with σb ~ 2.04×10^-4 S/cm along with decent ceramic-polymer interfacial ionic conductivity (σi) 4.20×10^-5 S/cm was characterized for Na stripping/plating tests at 100ľA/cm2. These findings shed light on prospects of conformal composite-electrolyte with “polymer in ceramic” electrolyte model to circumvent the challenges of the conventional solid ceramic or polymer electrolyte batteries. |
