A type of EDLC that is boosted by an electrolyte with both a catholyte and anolyte.
Electrochemical capacitors are fast recharging energy storage systems that provide power to heavy-duty electronics and electric vehicles. Electrochemical double-layer capacitors (EDLCs), also known as supercapacitors, store electric charges via electrostatic absorption of electrolyte ions into an electrolyte surface. These devices are superior to batteries because electrons are not transferred between the electrode and the electrolyte. The main problem with conventional capacitors is their low-to-moderate energy density. This low energy density is ascribed to the native surface-limited charging process at the electrode, which makes storing charge inefficient.
Researchers at the University of California, Santa Barbara have developed a type of EDLC that is boosted by an electrolyte with both a catholyte and anolyte. This type of EDLC can be used to create rechargeable batteries with extremely long lifetimes of up to 16 times as long as state-of-the-art lithium ion batteries. They are also cheaper, easier to manufacture, and specialize in quick power delivery, complementing existing batteries in electric vehicles (EVs) and working as the electric power source in hybrid vehicles.
