Ampcera Inc., a trailblazer in solid-state electrolyte manufacturing and next-generation solid-state battery development, has made a groundbreaking achievement in its all-solid-state battery (ASSB) technology. The company announced that it has successfully accomplished a fast-charging milestone, taking the battery from 0 to 80% state of charge in less than 15 minutes at a peak C-rate of 4C.
This remarkable progress signifies a major leap forward in fast-charging potential for electric vehicles (EVs), which is essential for their widespread adoption. Ampcera’s ASSB technology is specifically designed for extreme fast charging, utilizing IP-protected sulfide solid-state electrolyte materials. To achieve a high energy density goal of 400 Wh/kg, the battery incorporates a high-capacity NMC cathode and a silicon-based anode. Another significant advantage of ASSB is its elimination of any liquid or semi-solid electrolyte, ensuring the highest levels of battery safety during rapid charging cycles.
In extensive lab-scale testing, the pouch cells exhibited less than 5% capacity decay after 300 cycles of repeated fast charging at a 4C peak C-rate. This demonstrates the potential for a long cycle life of over 1000 cycles in commercial cells once fully developed. Ampcera’s high-performance solid-state electrolyte materials have surpassed the ambitious fast-charging benchmark set by the U.S. Department of Energy (DOE), achieving an 80% charge in under 15 minutes.
The prolonged wait times at public charging stations, particularly in urban areas with limited at-home charging options, have given rise to significant charge anxiety among current and potential EV owners, hindering widespread adoption. Ampcera aims to address this critical challenge by advancing the development and commercialization of its fast-charging ASSB technology through strategic partnerships with industry leaders.
Last year, Ampcera was awarded a $2.1 million grant from the U.S. DOE’s Advanced Research Projects Agency-Energy (ARPA-E) as part of the EVs4ALL program. This grant underscores the company’s commitment to collaborating with key industry partners, including a major U.S. automaker, to bring all-climate, fast-charging ASSB technology to the market.
With over 25 U.S. and international patents and patent applications protecting its core technologies, Ampcera continues to lead the way towards a sustainable energy future. The breakthrough achieved by Ampcera’s all-solid-state battery technology represents a significant step forward in revolutionizing fast-charging capabilities for electric vehicles, bringing us one step closer to a world powered by efficient and convenient transportation options.
