Hyundai starts solid-state battery production in March


Hyundai starts solid-state battery production in March

The official unveiling of Hyundai's solid-state battery pilot plant is just one month away. The official opening ceremony of the Korean plant in Uiwang will take place in March.

To explain how much the group believes in this new battery, suffice it to say that they have christened it Dream. No technical details are available at the moment, but Hyundai says that it will represent a huge step forward in terms of range, charging speed, safety and, of course, energy density.

Different batteries for different electric cars

The news that Hyundai was working on its own solid-state battery was first reported in 2023, during the company's annual investor day, where Hyundai announced in no uncertain terms that it wanted to become a leader in electric car batteries.

At the same time, it announced an investment of €9 billion over 10 years to establish itself in the market with various technologies. These include solid-state batteries, such as lithium-ion batteries with lithium-iron-phosphate or nickel-manganese-cobalt chemistry.

There is also the partnership with Factorial

Back at the Uiwang plant, Hyundai has announced that production of the Dream batteries will begin as early as next month and that it will be able to present an electric prototype using this new battery by the end of 2025.

However, it is still early days for mass commercialisation. At the moment, the group's top management is talking about an unspecified date in 2030. In the meantime, however, Hyundai is also investing in partner companies to develop similar technologies.

In the spring of 2024, for example, a partnership was announced with Mercedes and Stellantis to support solid-state specialist Factorial Energy, which is also backed by LG Chem.
