ABSTRACT
Herein, we have developed a sodium ion based aqueous energy storage device with nickel prussian-blue-analogue (Ni-PBA) positive and functionalized carbon-black negative electrodes in 1â
M Na2 SO4 electrolyte solution. The components required to develop the device, i. e., stainless steel (SS) current-collectors, absorbent-glass-mat separator, electrolyte, carbon-black, and precursors of Ni-PBA, are all environmentally benign and inexpensive. To minimize the corrosion of pristine-SS, polyaniline coating on the SS surface is applied by inâ
situ electrodeposition method. The full cell exhibits a specific capacity of 28â
mAh g-1 with 90 % Coulomb efficiency (@0.2C), an energy density of 34â
Wh kg-1 (@20â
W kg-1 ), a power density of 100â
W kg-1 (@18â
Wh kg-1 ) and a good life cycle (70 % capacity-retention over 500â
cycles @1.0C rate) within the 0-1.2â
V window. The cell performance is further tested under variable temperatures, and 0-50 °C range is reported to be the working window for this cell.
