To boost the energy efficiency of advanced energy storage technologies, various innovative strategies, i.e. smart electrode materials, hybrid mechanismsHybrid mechanisms, and progressive ionic media, are currently being explored to overcome the escalating energy demand as well as minimize the negative consequences resulting from the overuse of fossil fuels. In this regard, hybrid metal-ion capacitors like Li+ and Na+ capacitors are experiencing great attention due to their ability to deliver high energy densityEnergy density, faster energy delivery, and long cycle life. The advantages of these hybrid metal-ion capacitors arise from the synergetic properties derived from both conventional batteries and supercapacitorsSupercapacitors.
