Ampcera Inc., a renowned leader in solid-state electrolyte manufacturing and the development of next-generation solid-state batteries, has achieved a remarkable milestone in their all-solid-state battery (ASSB) technology. Their batteries can now charge from 0 to 80% state of charge (SOC) in under 15 minutes, boasting a peak C-rate of 4C. This breakthrough demonstrates the immense potential of ASSB in addressing the key requirement for the widespread adoption of electric vehicles (EVs) – fast charging.
Ampcera’s ASSB technology is engineered for extreme fast charging, utilizing sulfide solid-state electrolyte materials that are protected by intellectual property. With a combination of a high-capacity NMC cathode and a silicon-based anode, Ampcera aims to achieve an outstanding energy density goal of 400 Wh/kg. Moreover, their ASSB technology is entirely devoid of any liquid or semi-solid electrolyte, ensuring the highest levels of battery safety, especially during rapid charging cycles.
To showcase the durability and longevity of their ASSB technology, Ampcera conducted tests on lab-scale pouch cells. These cells exhibited less than 5% capacity decay after undergoing 300 cycles of repeated fast charging at a peak C-rate of 4C. This provides a promising indication of a potential life cycle exceeding 1000 cycles once the technology is fully developed for commercial cells.
By achieving this remarkable charging milestone, Ampcera aims to alleviate the growing concerns surrounding extended wait times at public charging stations. This is particularly crucial in urban areas where at-home charging options are limited. The aim is to address the consumer charge anxiety that hinders the widespread adoption of EVs.
To further their mission, Ampcera plans to develop and commercialize their fast-charging ASSB technology through strategic partnerships with industry leaders. In 2023, they were awarded a substantial $2.1 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) as part of the EVs4ALL program. This grant underscores Ampcera’s dedication to collaborating with key industry partners, including major U.S. automakers, in advancing the development and commercialization of all-climate, fast-charging ASSB technology.
Ampcera’s achievement in fast-charging all-solid-state batteries marks a significant milestone in the progression of electric vehicles. This technology has the potential to revolutionize the EV market by alleviating charge anxiety and encouraging mass adoption. With their commitment to innovation and sustainable energy solutions, Ampcera is at the forefront of shaping the future of electric vehicles.
