Ultracapacitor battery hybrid with 30 year life?
Zap&Go’s new Carbon-Ion or C-Ion battery is the result of years of research at the prestigious University of Oxford that is currently in its 3rd generation, according to Voller. “It’s a supercapacitor that performs like a battery,” Voller said. “The conventional supercapacitor is great at charging really fast but doesn’t hold onto its energy for very long.”
The breakthrough came when Zap&Go used carbon nanotube technology to combine the fast charging benefits of supercapacitors with the energy storage characteristics of a battery. The result is an extremely fast-charging battery that is built without the need for any rare earth metals or toxic chemicals like the cobalt that underpins many of today’s lithium-ion battery chemistries.
In Zap&Go’s Carbon-Ion battery, “the principle material is carbon, which is readily available in many forms,” Voller said. For now, Zap&Go is using carbon sourced from coconut shells, but Voller noted that he expected the source to change over time as demand grows.
In addition to ultra-fast charging, Zap&Go’s new Carbon-Ion battery is poised to change the energy storage game because of its impressive lifespan expectations. “We last a long time,” Voller said. “It would be a 30-year useful life or 30-year warranty,” which is a far cry from the 10- to 15-year lifespans expected from today’s lithium-ion batteries.
