Solid State Batteries by 2028? Nissan Plans First EV with New Tech

But will ultra fast charging EV batteries be enough to convince the public?

Nissan is anticipating the completion of its solid-state battery technology development for mass production in 2028. While development work continues, the Japanese automaker believes it is in a good position to introduce pilot production in 2025 and gradually enhance the technology.

According to David Moss, Nissan’s senior vice-president for research and development in Europe, the company is among a group of leaders in solid-state battery technology development, aiming to decrease the cost by 50%, double the energy density, and provide three times the charging speed when compared to lithium-ion batteries. The development work is being carried out in Japan and England.

Although several car manufacturers and suppliers are also working on developing solid-state batteries, Moss’s team is concentrating on developing a genuine solid-state battery that does not require a liquid electrolyte. He noted that some solid-state batteries still rely on liquid electrolytes, which is problematic because the liquid boils, affecting the energy storage and transfer efficiency and the power supplied.

While solid-state batteries are still in the prototype phase, they have the potential to provide several benefits compared to lithium-ion batteries, which currently power most electric vehicles (EVs) on the market. One of the benefits is faster charging, with the assumption that driving range will be less of a concern if reliable charging is as quick as refueling a gasoline tank. As a result, automakers may construct EVs with smaller battery packs and (hopefully) reduce the price gap between an EV and a comparable gasoline-powered model, passing the savings onto buyers.

It is too early to predict which models will feature solid-state technology, although a new platform and factory assembly may be required, according to Autocar. Moss also clarified that the technology is not tied to a specific vehicle program to prevent other projects from being delayed if the 2028 deadline is not met. Nissan continues to invest in lithium-ion technology to be cautious.

Nissan has spent €7.8 billion (about $8.4 billion) on EV development so far, with its first mass-produced electric car being the original Leaf unveiled in 2010, and executives plan to spend an additional €15.6 billion (approximately $16.8 billion) in the future.
