Nissan has set out plans for a pilot production plant for solid-state batteries to be operational in 2025, supporting initial application engineering by 2026 and vehicle application in 2028.
Nissan Senior Vice-President of Research and Development in Europe, David Moss, described the solid-state sodium batteries as ‘all-solid-state’.
An all solid state battery is a type of rechargeable battery that uses solid electrolytes instead of liquid or gel electrolytes. This type of battery is more stable and efficient than traditional batteries, making it a promising candidate for electric vehicles and other high-powered applications.
“Can you delete the liquid electrolyte out of the battery? This is where we think we’re leading,” said Moss. “Some solid-state batteries still have the liquid electrolytes, and this is an issue, as that liquid boils. The efficiency of that energy in storage and transfer and the power you put into it will be impacted.”
Alongside continuing to develop lithium-ion batteries, the company intends to roll out a new-generation lithium battery in the coming years and a cobalt-free li-ion battery by 2028 that could reduce battery costs by up to 65 percent.
Nissan’s battery research team is tasked with producing advanced EV batteries that have greater energy density than lithium-ion and a longer lifespan.
This will not only reduce the total weight of the vehicle, which will improve handling, acceleration and fuel efficiency, but reduce dependency on raw materials.
