It opens the door to a new era of electric efficiency. Researchers believe they’ve discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging and discharging.

Can a supercapacitor store more energy?

Credit: Tao Wang/ORNL, U.S. Dept. of Energy Guided by machine learning, chemists at the Department of Energy’s Oak Ridge National Laboratory designed a record-setting carbonaceous supercapacitor material that stores four times more energy than the best commercial material.

Could a new capacitor overcome energy storage challenges?

However, their Achilles’ heel has always been their limited energy storage efficiency. Now, Washington University in St. Louis researchers have unveiled a groundbreaking capacitor design that looks like it could overcome those energy storage challenges.

Why is research important for enhancing the capacitance of a supercapacitor?

Research on factors enhancing the capacitance is crucial for producing next-generation supercapacitors with greater efficiency. The vitality of this research lies in improving energy storage devices, transport electrification, stabilizing electrical grids, powering portable electronic devices, and reducing intermittency issues.

Should supercapacitors be hybridized with complementary storage technologies?

As mentioned, multiple times in this report, supercapacitors have not been traditionally well suited for stand-alone, long-duration energy storage but may have substantial benefit when hybridized with complimentary storage technologies. Ideal combinations are those in which the strengths of one technology offset the weaknesses of another.

Should EDLC supercapacitors be hybridized?

There has been substantial discussion around the hybridization of EDLC supercapacitors and other energy storage devices, such as lithium-ion batteries or pumped storage hydropower, to meet long-duration storage needs.
