The Lotus Elise-based demonstration concept car for the Nyobolt/Callum
fast-charging lithium-ion battery technology; the companies claim the
smaller battery enabled by fast charging means much-reduced weight
penalty compared to current EVs.
a typical charging-temperature range of around 35° to 40° C
(95° to 104° F), in the range seen during the demonstration.
The Callum/Nyobolt demonstrator is fitted with a 35-kWh
battery. The potential for such rapid charging means that a
large-capacity battery might not be necessary because recharging
would take little more time than filling a conventional
vehicle's fuel tank. The battery could be used in hybrid,
fuel-cell hybrid and ICE hybrid vehicles because it could recharge
so rapidly. " We could make a hybrid battery do the job
of a big battery, basically, " said Hutchins.
Nyobolt's core technology is the anode material. " It's the
anode that limits the charging and everybody's been focused
on the cathode " , says Hutchins; " That's more important on the
discharge side. People have just had the same old anode for
years and years, so we're focusing
on the anode. But the anode doesn't work on its own. It's a

system, there's probably a dozen components in one battery
cell and they all have to work together. " Nyobolt's U.S.-based
team, under Chief Technology Officer Brian Barnett, includes
engineers involved in developing Formula One's KERS (Kinetic
Energy Recovery System) battery, with extensive expertise in
high-power batteries.
" The anodes are a lot more forgiving than the cathode material.
We haven't really faced any issues at all " , Hutchins continues.
" Obviously, there's a lot of engineering that's gone into the
anode to make it last as long as it does, but we don't have any
stability issues there, it's not limiting the life of the battery.
When a battery dies, it's usually more to do with the cathode. "

November 2023. Nyobolt's first demonstration of the technology
was not on a vehicle. " We started with a 12-volt battery in
a robotic vacuum cleaner " , says Dr Hutchins, " We were able
to show it charging in three minutes and then vacuuming for
30 minutes. Previously, it spent 15 percent of its time cleaning
and 85 percent charging and we switched that around. " The
idea then developed to see if the same concept could be
achieved in an EV.
