TECH FOCUS:SUSTAINABLE
ENERGY TECHNOLOGY
The many advantages of electric
vehicle (EV) technology, as well
as the rapid technological
advancements that have pushed
EVs into the mainstream, have
redefined the automotive
industry in the past decade. The
appeal of zero tailpipe emissions
and replacing gasoline with
electrons has made EV adoption
an essential objective for fighting
climate change while reducing
oil consumption, and industry is
rising to meet the challenge. As
many policymakers have
embraced the societal benefits
of electric vehicles, drivers have
been delighted by newer models
with longer ranges, shorter
recharge times, greater utility,
and unmatched acceleration.
These capabilities also enable EV
drivers to adventure in wild
places and reconnect with nature
without contributing to local air
pollution.
As EV technology has
proliferated, important questions
have surfaced about how we
meet growing demand for
electric vehicle batteries.
Specifically, the industry must
face the challenge of sourcing
certain critical minerals for which
existing commercial supplies are
concentrated in countries that

may lack adequate labor protections, environmental
safeguards, or transparency.
As always, innovation offers a path forward.
Lithium-ion has been the predominant battery
chemistry for electric vehicles and personal devices so
far, but it's just one of many viable battery
chemistries. Lithium Iron Phosphate (LFP) batteries
demonstrate that new chemistries can be paired with
the right use-case to create a win-win for
manufacturers and drivers. This chemistry is still
relatively young, but notably does not require cobalt
or nickel, and is manufactured from safer and more
abundantly available minerals. Current LFP
technology is ideal for applications where lower costs,
safety, and extended durability are prioritized over
incremental range gains and extreme highperformance.
As Rivian's commercial vehicle
technology evolves, we are focused on just a few of
