ZapGo’s Carbon-Ion tech combines power density of supercapacitors and energy density of batteries

Williams Advanced Engineering has selected ZapGo, a spinout of Oxford University, to join a consortium working to develop next-generation battery systems for EVs (part of the UK government’s Faraday Battery Challenge).

ZapGo’s Carbon-Ion technology, based on carbon nanomaterials including graphene, is intended to combine the power density of supercapacitors and the energy density of rechargeable batteries. The C-Ion cells work in a similar way to supercapacitors, but use different carbon and electrolyte materials that ZapGo says are safer and easier to recycle, and enable the devices to operate at higher voltages, resulting in higher energy density.

ZapGo says that its C-Ion cell can provide specific power characteristics between one and two orders of magnitude higher than those of a Li-ion cell. It is designed to be classified as non-flammable and non-hazardous for transport.

“It’s an important validation of our technology to be invited to work with the Williams team,” said CEO and founder Stephen Voller. “We want to demonstrate the viability of a hybrid battery management system that goes beyond what’s currently available to EV manufacturers. The time is right to demonstrate that our Carbon-Ion technology can deliver safe, fast charging.”

    Carbon again. Maybe cobalt and lithium supplies won’t be such an issue?

    Home charging?

    So let’s see if I got this. There is a battery in the EV, it’s recharged by a much larger in ground battery at a station. That in ground battery is either recharged by another truck hauled battery which was recharged at some other location or the in ground battery is recharged with off peak grid power at the station. Seems a bit over redundant to me.

    If that really makes sense, then having more batteries charging other batteries which will charge more batteties in the process would be even better. That or having less would be better. Which is it?

    Really! Just develope a fast charge EV Battery and actually bring them to market. That would be just fine, if it doesn’t take 30 years

      No, you didn’t quite get it. The in-ground battery can be recharged quickly from a mobile battery bank when necessary, but not that it shall be. Increased in-ground capacity can avoid running out of juice, too.
      “Just develope a fast charge EV Battery and actually bring them to market” is thinking that ignores ongoing battery research and development. Presently, extreme charging requires EV battery pack cooling to manage the heat released. Cooling that may also be provided through the charging connector.

        The article was about a new fast charging “5 minutes” battery for EV’S, which is the battery in the electric car itself. Anytime a second (another) battery is used to charge the first battery there are energy losses. Meaning more energy is needed to charge a battery than can be delivered by it as it’s discharged.
        So! Using a battery in the ground (another battery) to charge an EV with have losses incurred in the process and using a battery brought to the station to charge the in ground battery which will then charge a EV Battery incurrs DOUBLE the losses. That was my point. How does that make sense?

          ZapGo was simply showcasing fast charging of their Carbon-Ion tech without suggesting power losses. Which reminds me: I’m too lazy right now to determine if Carbon-Ion tech is more or less efficient during charging than existing lithium-ion cells; internal resistance and such…
