1. A micro-supercapacitor comprising:
a. a first electrode;
b. a second electrode;
c. a first conductor interfaced with the first electrode;
d. a second conductor interfaced with the second electrode;
e. a non-conductive liner contacting at least a portion of the first conductor and the second conductor; and
f. an electrolyte in contact with the first electrode and the second electrode,
wherein at least one of the first electrode or the second electrode comprises an interconnected corrugated carbon-based network (ICCN) having a plurality of expanded and interconnected carbon layers,
having a plurality of metal nanoparticles deposited in the ICCN, and
wherein the micro-supercapacitor maintains at least 60% of the stack capacitance when operated at a current density of about 1.84×104 mA/cm3.
