Decarbonizing
the EV battery
SUPPLY CHAIN
SUSTAINABILITY | BATTERY SUPPLY FEATURE
China is the largest producer
of greenhouse gases during
vehicle production.
" With hundreds of new factories
coming online, the amount of
scrap produced would finally make
recycling a cost-effective endeavor. "
Li-Cycle says its EV battery recycling method is a drastic improvement over
processes that use smelting, because it maximizes retention of usable chemicals
and minimizes the creation of polluting waste.
One potentially controversial area the report discusses in in battery
size/vehicle range. The longest-range EV currently can travel more
than 405 miles (662 km) on a single charge. And in 2022, the number
of EV models available with a range longer than 300 miles (483
km) tripled. But it's well known that the average daily driving distance
for U.S. commuters is less than 40 miles (64 km). The report
calls that delta a plainly underused resource.
" One radical way to reduce emissions would be to build smaller battery

packs tailored more toward consumer needs, " the report
suggested, citing that in China, the best-selling EV in 2021
was the Wuling Hongguang Mini EV, with a 14-kWh battery
and a range of 75 to 106 miles (121 to 171 km).
Breiter said that there is a segment of the industry
where the range of current products matches the usecase:
" If you look at the range of all of those last-mile
delivery vehicles, which are now being electrified, those
never have such a long range as passenger cars, " he
said. " Last-mile delivery vehicles are often specified with
a range starting at about 100 miles (161 km). This is completely
sufficient for the use case. And those cars are
driving all day through the city, " Breiter said. He added
that it would take concerted communications efforts
from the industry, media and government to make the
case that would, hopefully, convince consumers to ask
why they want to pay for such unused range.
