|Researchers at Purdue University have developed composite electrodes to improve the energy density of supercapacitors. This hybrid electrode framework demonstrates a specific capacitance over 262 F/g and an energy density of ~52.4 Wh/kg while keeping a high power density (~3680 W/kg). Another advantage of this electrode is its high durability, maintaining high capacitance retention over 50,000 charge/discharge cycles. This technology has applications in energy storage solutions and takes an important step towards bridging the gap between the energy density differential between capacitors and batteries.
