We developed sodium ion based supercapacitor devices with high energy and power density and cyclic stability using nanomaterials for the electrodes and enhancers in the electrolyte. The cathode material was composed of NaCl salt, MWCNT (multi-walled carbon nanotubes), sulphur and cellulose, with compatible anode composition.
For the cathode materials of sodium ion based supercapacitor/battery, the current trend is use of layered oxides and polyanionic compounds [6]. Sodium ion hybrid supercapacitor was fabricated with 3D graphene/rGO/MoS 2 and achieved very good energy density (140 Wh/kg at power of 630 W/kg) with good cycling stability [7].
Good redox stability in cyclic voltammetry of upto 30 cycles. Sodium ion based supercapacitors have great potential to replace Li-ion based systems in future energy storage devices with advantages of power density, stability and cost, but with a demerit of low energy density achievable.
CV (cyclic voltammetry) curves were acquired using potentiostat-galvanostat at 0.1 V/s (Model: CHN). A specific capacitance of 14.6F/g, high energy density of 117 Wh/kg, a power density of 12 kW/kg and good cyclic stability over 30 redox cycles was achieved. 1. Introduction Sodium ion based supercapacitors have made progress in last four years.
Batteries store energy electrochemically as charged ions, while supercapacitors store electrical charge electrostatically on a surface. This gives supercapacitors the advantage that they can be charged very quickly, and charged and discharged many times, but they can’t store as much energy as a battery of the same weight.
Sodium-ion hybrid capacitors (NICs) can combine the benefits of high power capacitors and high energy batteries at a cost potentially lower than that of Li analogues. However, research on NICs is in the nascent stage and requires significant attention to enable their use in practical applications.
