Meet the Battery Startup Taking on China’s Giants

Taiwanese startup ProLogium is aiming to disrupt the battery industry by mass-producing solid-state batteries by 2027. The company is scaling up operations with a new gigafactory in France and a planned Nasdaq listing to compete with established Chinese battery manufacturers.
Why it matters
Solid-state battery technology is considered a critical next step for safer, more efficient energy storage, potentially shifting the global battery manufacturing landscape.
But there’s still hope for China’s rivals. If another company can crack the next generation of battery technology, it may still be able to take the lead. And the battery industry already has a consensus on what that technology might be: solid-state batteries.
Today, almost all batteries have liquid electrolytes that carry ions between the positive and negative sides. But the liquid can spill, vaporize, and even catch fire. So for decades, scientists have tried to replace it with a solid electrolyte that could make batteries safer, more powerful, and more resilient to cold temperatures.
