Rimac Technology plans 2030 solid-state batteries with ProLogium

Rimac Technology intends to begin producing solid-state batteries as early as 2030, but it will not be doing it alone. The company - part of the Rimac Group, which also owns Bugatti - has signed a memorandum of understanding with Taiwanese cell manufacturer ProLogium Technology, making Rimac’s battery-integration expertise available to the project. The partnership was announced at the Munich Motor Show in September.

Rimac Technology solid-state battery development timeline

The plan is for Rimac to create a production-ready, high-performance modular battery system for cars, built around ProLogium’s fully inorganic, “superfluidised” ceramic lithium solid-state battery. The first sample unit is expected to be ready in 2027.

In 2028, the two companies aim to deliver a second sample that can be installed in vehicles and assessed for performance, safety and durability. By 2030, the battery should be prepared for small-scale production, with the option to scale up to mass production later on.

Possible use in the Bugatti Tourbillon plug-in hybrid

If everything goes to plan, the battery could end up powering a Bugatti Tourbillon plug-in hybrid, according to Nurdin Pitarević, COO of Rimac Technology. “Such an innovative technology in such an innovative car would be the perfect story,” he said. “But for now, it’s only a wish.”

Proven experience

Pitarević said Rimac and ProLogium have already been working together for around two years on the development of a 100 kWh battery, with an expected range of between 500 and 600 km.

The target is also for this battery to support charging from 10% to 80% in just 10 minutes, while achieving an energy density 20% to 30% higher than rival solutions.

At present, the project is roughly 50% complete in areas such as safety, range and charging, the executive added.

ProLogium’s European factory

While several companies are cancelling investments in battery plants, ProLogium remains committed to its facility in France. The start of operations is scheduled for 2028, and the total investment in the project amounts to €5.2 billion.
