Croatian electric vehicle technology company Rimac Technology unveiled itsNew battery platformThe company's biggest highlight is its pure solid-state battery design, developed in collaboration with Taiwan's ProLogium and Mitsubishi Chemical. This solution is lighter, safer, and offers higher energy density than traditional lithium-ion batteries. It has the potential to be used not only in supercars but also in the broader electric vehicle market.
Experience in cooperation with multiple brands
In addition to developing its own Nevara supercar, Rimac also provides electrification technology to supercar manufacturers such as Aston Martin and Koenigsegg. The launch of its solid-state battery platform signals Rimac's attempt to establish a new level of technological influence in the core powertrain sector of electric vehicles, further transforming its role from a supercar brand to an electric vehicle technology provider.
Industry expectations for solid-state batteries
Solid-state batteries have long been regarded as the "next-generation holy grail" of the electric vehicle industry. Compared with the usage characteristics of traditional liquid lithium batteries, solid-state batteries not only have higher energy density, but also reduce the risk of fire and can provide longer driving performance in the same volume.
According to a study conducted by European research institute Imec last year, solid-state batteries do have the potential to improve efficiency and reduce manufacturing costs, which is crucial for the popularization of electric vehicles.
However, despite years of hype surrounding solid-state batteries, commercialization remains slow. Nissan has stated that it will not launch its first pure solid-state battery electric vehicle until fiscal year 2028. While Rimac showcased its technological achievements, it also offered no specific timeline for product launch.
Connection with Taiwan
Notably, one of Rimac's partners in this collaboration is ProLogium, a Taiwanese solid-state battery startup. ProLogium has been actively collaborating with international automakers and establishing a new European facility. This collaboration with Rimac and Mitsubishi Chemical not only highlights Taiwan's crucial position in the new battery technology chain, but also demonstrates the potential of the "Silicon Island" to expand its industrial strength beyond semiconductors into new energy sectors.
Prior to this, ProLogium hadAnnounced cooperation with Gogoro, launched the first swappable solid-state battery prototype for electric vehicles, which can be used in the existing Gogoro Network smart battery swap network.
In addition to collaborating with Gogoro, ProLogium has previously collaborated with Mercedes-Benz and received millions of euros in investment from Mercedes-Benz to develop new battery technology. The company plans to use solid-state batteries to store higher-density electricity while also reducing battery size and weight, thereby extending the maximum driving range and vehicle speed of electric vehicles.
Market prospects and challenges
Although major automakers such as Toyota, Volkswagen, Nissan, and BMW have invested in solid-state battery research and development, the technology still faces three major challenges:
• Insufficient manufacturing yield makes large-scale production difficult.
• High material costs make it impossible to reduce vehicle prices quickly in the short term.
• Reliability verification still takes time, especially stability under high temperature and long-term cycles.
Therefore, even if Rimac demonstrates its technological breakthrough, it may still take several years or even a decade to see solid-state batteries completely replace existing lithium batteries.
Conclusion
While Rimac's unveiling of its solid-state battery platform remains a technical demonstration, it not only demonstrates the electric vehicle industry's continued pursuit of breakthroughs, but also elevates the visibility of Taiwanese startups on the international stage. For the overall market, solid-state batteries are a crucial piece of the puzzle toward the next generation of electric vehicles. However, before they can truly become widespread, they still face numerous challenges in terms of technology, cost, and supply chain.
