Solid-state battery maker ProLogium receives another Edison Award

TAIPEI, April 23, 2021 /PRNewswire/ -- The 2021 Edison Awards gala was held in Florida on Thursday, April 22. Solid-state battery maker ProLogium has been awarded a bronze award. ProLogium has been selected as a finalist for the category of Critical Human Infrastructure and is chosen for its proprietary ASM technology designed for battery safety.

Founded in 1987, the Edison Awards is an annual celebration of innovative technology highlighting excellent inventions for the betterment of human life. ProLogium is the only solid-state battery company in the world that has been recognized two times in the Awards' history. Back in 2019, ProLogium won its first Edison Gold Award for its patented BiPolar⁺ technology. The BiPolar⁺ technology took solid-state battery performance to a whole new level, while the ASM technology guarantees absolute safety. This signifies another major step forward for the application of solid-state battery in EV cars.

Why did ProLogium want to develop the ASM technology for the market?

Absolute safety can only be achieved when battery safety is assured at the cell level. Unsafe cells can lead to risk of thermal runaway even when the module is well protected. Solid-state battery is intrinsically safe because of its use of solid-state electrolyte. This means passive safety is guaranteed. However, when large quantities of electrodes and cells are densely packed and stacked, innovative technology is needed to enable active safety.

The ASM, or Active Safety Mechanism, is a technology developed by ProLogium that actively terminates the thermal runaway reaction and ensures the safety of battery cells. The ASM is unlike any other active safety mechanism that came before it. We have seen mechanisms using flame retardant to reduce combustion, or adding additives to slow down the electrochemistry and delay thermal runaway. However, these methods will inevitably hinder battery performance. That is why ProLogium decided to take a more fundamental approach and develop a mechanism that reduces energy and prevents thermal runaway.

As stated by Martin Eberhard, co-founder, original CEO and chairman of Tesla, "ProLogium's solid-state electrolyte battery technology is the most exciting new development I have seen in this field. The combination of safety, aging characteristics, fast charge rate, and bipolar packaging, all without sacrifice energy density, and at a competitive price, make ProLogium cells the best I have seen for automotive applications."
