ABSTRACT = {A supercapattery merges the advantageous characteristics of batteries and supercapacitors 
(SCs). During this research, we synthesized strontium sulfide (SrS) using the hydrothermal 
method, and then we doped it with nitrogen/graphene quantum dots (N-GQDs). For SrS/NGQDs,
the Brunauer-Emmett-Teller (BET) analysis determined the total surface area to be 
15.50 m<sup>2</sup>
/g. Using the three-electrode assembly, the composite strontium sulfide (SrS/NGQDs)
 revealed a specific capacity (C<sub>s</sub>) of 737 Cg<sup>-1</sup>
. Battery-graded SrS/N-GQDs was 
utilized as anode and activated carbon (AC) as cathode to assemble a hybrid supercapacitor 
(SC). It delivered a remarkable power density of 1440 Wkg<sup>-1</sup>
, the SrS/N-GQDs//AC 
supercapattery displayed 167 Cg<sup>-1</sup>
 in terms of capacity and an energy density of 35.7 Whkg 
<sup>-1</sup>
. SrS/N-GQDs//AC maintained 91% of its initial capacity after 5000 cycles. SrS/N-GQDs 
has remarkable electrochemical performance, indicating its potential use as a nanostructured 
electrode in next-gen electrochemical energy storage (EES) devices.},
