When you think of Rimac, the first image that comes to mind is the blisteringly fast Nevera hypercar, a machine that redefined what electric performance could look like. But Rimac is not just about speed—it’s about innovation. At IAA Mobility 2025 in Munich, Rimac Technology unveiled its latest breakthrough: a solid-state battery system that could reshape the future of electric vehicles.

What Makes Solid-State Batteries Revolutionary?

Traditional lithium-ion batteries, while powerful, face limitations in energy density, charging speed, and safety. Solid-state batteries replace the liquid electrolyte with a solid one, offering several advantages:

  • Higher energy density: More power packed into a smaller, lighter battery.
  • Faster charging times: Potential to recharge in minutes rather than hours.
  • Improved safety: Reduced risk of overheating or fire compared to liquid-based cells.
  • Longer lifespan: Better durability and fewer performance losses over time.

For Rimac, these benefits are not just theoretical—they’re essential for pushing the boundaries of electric performance.

Rimac’s Strategic Partnerships

The new battery system was developed in collaboration with ProLogium and the Mitsubishi Chemical Group, two leaders in advanced materials and battery innovation. By combining Rimac’s expertise in high-performance EVs with their partners’ cutting-edge research, the company is positioning itself as a tier-one supplier for the automotive industry.

This is a crucial shift. Rimac is no longer just a boutique hypercar manufacturer—it’s becoming a technology provider for brands like Koenigsegg, Aston Martin, and Bugatti, all of whom rely on Rimac’s advanced EV solutions.

Beyond the Hypercar: Expanding Applications

While Rimac’s Nevera showcases what’s possible at the extreme end of performance, the new solid-state battery has far broader implications:

  • Mainstream EVs: Affordable cars could benefit from faster charging and longer ranges.
  • Luxury vehicles: Premium brands can integrate Rimac’s tech for superior performance.
  • Commercial fleets: Delivery vans and buses could see reduced downtime thanks to rapid charging.

By scaling production and refining costs, Rimac’s innovation could accelerate EV adoption across multiple segments.

Technical Highlights from IAA Mobility 2025

At Munich, Rimac showcased not only the solid-state battery but also next-generation e-axles and control systems. Together, these technologies form a complete ecosystem for high-performance EVs. Key highlights include:

  • Compact e-axles: Delivering more torque with less weight.
  • Advanced control domains: Smarter energy management for efficiency and performance.
  • Integrated systems: Batteries, motors, and electronics designed to work seamlessly.

This holistic approach ensures that Rimac’s innovations are not isolated components but part of a larger vision for electrified mobility.

Why This Matters for the EV Industry

The EV industry is at a tipping point. Consumers demand longer ranges, faster charging, and safer batteries. Governments are pushing for stricter emissions regulations. Automakers are scrambling to differentiate themselves in a crowded market.

Rimac’s solid-state battery addresses all these challenges:

  • Range anxiety: Higher energy density means longer drives between charges.
  • Charging infrastructure: Faster charging reduces reliance on extensive networks.
  • Safety concerns: Solid electrolytes minimize risks of thermal runaway.

In short, Rimac is not just building faster cars—it’s solving the fundamental bottlenecks of EV adoption.

Looking Ahead

The road to mass production of solid-state batteries is not without hurdles. Manufacturing costs, scalability, and reliability under real-world conditions remain challenges. However, Rimac’s track record of turning ambitious concepts into reality gives reason for optimism.

As Mate Rimac, the company’s visionary founder, has often emphasized, the goal is not just to build the fastest EVs but to push the boundaries of what’s possible. With this new battery, Rimac is doing exactly that.

Conclusion

Rimac’s unveiling of its solid-state battery at IAA Mobility 2025 marks a pivotal moment in the evolution of electric vehicles. By combining higher energy density, faster charging, and improved safety, Rimac is setting the stage for a new era of EV performance.

Whether powering hypercars like the Nevera or mainstream EVs from partner brands, this technology could redefine expectations across the industry. Rimac is no longer just a disruptor—it’s becoming a cornerstone of the electric future.
