Achieving high-performance parameters in NASICON-polymer composite electrolyte-based solid-state supercapacitors by interface modification.

ABSTRACT: The present study reveals a strategy to enhance the performance of solid-state supercapacitors based on activated carbon electrodes and a Na₃Zr₂Si₂PO₁₂ (NZSP) dispersed fast ionic solid polymer electrolyte membrane. The electrode-electrolyte interface is optimized using a novel 'solvent layer' approach to enhance supercapacitor performance. By adding a small amount of acetonitrile organic solvent (a few μL cm^-2) at the electrode-electrolyte interface and utilizing high surface area (1800 m² g^-1) activated carbon, significant improvements in specific capacitance, specific energy, specific power, and cycling stability are achieved. Device performance at various operating voltages and discharge currents reveals inter
