Nissan unveiled Friday a prototype production
facility for solid-state batteries in Yokohama, Japan, a critical step in the
automaker’s bid to develop and deliver an EV powered by the next-generation
battery technology by 2028. The company says it plans to manufacture
solid-state batteries for use in electric vehicles.
The materials, design and manufacturing
processes developed while producing the prototype at the Nissan Research Center
will be used in a pilot production line at Nissan’s plant in Yokohama in 2024.
Ultimately, Nissan is aiming to incorporate all-solid-state batteries in pickup
trucks and other vehicles as part of Nissan Ambition 2030, its long-term plan
for EVs to comprise half its global sales by the end of the decade.
Battery technology is seen by Nissan — and
many others — as the key to unlocking cheaper, longer-range EVs for the masses.
It’s prompted a growing list of automakers, startups and investors to bet on
solid-state batteries, a technology that uses a solid electrolyte and not a
liquid or gel-based electrolyte found in lithium-ion batteries.
“To further democratize EVs, the key
innovation is the battery,” Kazuhiro Doi, head of Nissan Research Center, said
in a briefing.
Nissan said that refining solid-state battery
technology can make EVs as affordable as gasoline-powered vehicles by the end
of the decade. Specifically, Nissan said all-solid-state batteries can be
reduced to $75 per kWh in fiscal 2028 and to $65 per kWh thereafter, placing
EVs at the same cost level as gasoline-powered vehicles.
Solid-state batteries have double the energy
density of a conventional lithium-ion battery, which theoretically translates
to longer range and faster charge times, all while using cheaper materials than
other EVs on the road today. In addition to higher energy density, these
batteries last longer and are considered safer than a lithium-ion battery.
That’s why several automakers, including
General Motors, Stellantis, Mercedes-Benz and Ford, have invested in
solid-state batteries startups as they race to electrify their portfolios.
Volkswagen-backed QuantumScape aims to begin selling them in 2024, followed by
a production model from Toyota in 2025.
However, commercializing solid-state
batteries for electric vehicles has proved challenging. Currently, the
batteries are expensive to manufacture and difficult to scale
And while the benefits are plentiful, even
Nissan acknowledges that even batteries with a solid electrolyte are not
without risk. A liquid electrolyte, which is found in today’s lithium-ion
batteries, can be a fire risk. But doubling the energy density into a battery
also could be dangerous.
