Why solid-state batteries will revolutionize EVs

One of the main barriers preventing electric cars from overtaking traditional vehicles is the cost and performance of batteries. While advancements have been made in range, the infrastructure for charging still poses a challenge. The transition to solid-state batteries (SSBs) is seen as a potential solution to these issues, but what exactly are SSBs and when can we expect them in the automotive market?

What are solid-state batteries, and who’s making them?

Changing the basics of battery tech

A key component of any battery is its electrolyte, responsible for transporting ions during charging and discharging. Traditional batteries use a liquid lithium-based electrolyte, while solid-state batteries (SSBs) replace this with a solid electrolyte made of oxides, sulfides, or polymers. This shift offers improved efficiency and safety in battery technology.

Various companies, including Factorial, Solid Power, and QuantumSpace, are developing SSB technology in partnership with leading automakers like BMW, Hyundai, Stellantis, Mercedes-Benz, and Volkswagen. In-house development is also underway at companies like Honda, Toyota, and Nissan, with a focus on reducing costs and enhancing production efficiency.

The primary advantage of solid-state batteries is their increased energy density. Companies like Factorial have achieved significant improvements in energy density, enabling greater range without the need for larger battery sizes. Additionally, SSBs charge faster, offering the potential for quicker and more convenient charging experiences for electric vehicle owners.

Moreover, solid-state batteries offer enhanced thermal stability, minimizing range loss in extreme temperatures and reducing the risk of fires. These improvements make SSBs a promising technology for the future of electric vehicles.
