Sinonus carbon-fiber structural batteries could extend range of electric CVs
Carbon-fiber structural batteries are
not entirely new, but now Sinonus, a
company spun out of Chalmers
Technical University in Gothenburg,
Sweden, is further developing the technology
with carbon fibers that double
as battery electrodes. The technology
has already been demonstrated in lowpower
applications, and Sinonus will
now develop it for use in a range of
larger applications including, first, IoT
devices and then drones, computers,
electric vehicles and airplanes.
By integrating the battery into carbon-fiber
structures, Sinonus believes
that an EV's weight could be reduced
while the driving range could increase
by as much as 70%. The carbon-fiber
technology used by Sinonus originated
at Oxeon, another Chalmers spin-off.
The cells can be built incredibly thin
The Sinonus composite battery cell can be built incredibly thin - less than 0.1 mm.
- less than 0.1 mm deep - or quite
large. " I don't see that we can replace
the lithium battery in the near future, and
that's because there's not enough suitable
volumetric space in a car, " recently
appointed Sinonus CEO Markus
Zetterström told SAE Media. Zetterström
previously led strategy and transformation
at SKF Group. " It has to be certain
potential structures. We can add capacity,
and by doing so, you could maybe
replace a quarter or a third of the original
battery, so you could lower the weight. "
Zetterström believes the technology
could be most effective initially by limiting
subsystems in electric vehicles. " You
can limit part of the subsystems that are
currently using power from the generator,
