Products & Services

While Ampcera continues to develop its proprietary engineered solid-state electrolyte materials and revolutionary scalable manufacturing technologies for integration in batteries, our team has successfully commercialized a series of solid-state electrolyte materials.  Compared to flammable liquid electrolytes, batteries made with solid-state electrolytes have the advantages of higher energy density, faster charging, better safety, long term stability, and ultimately lower cost.

200+ industry customers and partners

Commercially available Ampcera® solid-state electrolyte materials include sulfides (e.g. engineered Argyrodite, LGPS, LSPS, etc.), garnet-structure oxides (e.g. engineered LLZO), and more. 

These products can be ordered through MSE Supplies (

Ampcera’s All-Solid-State Battery Technology Surpasses U.S. DOE’s Extreme Fast-Charging Goal of 80% Charge in 15 Minutes

Pioneering the Future of Fast-Charging All-Solid-State Batteries

TUCSON, Ariz.February 15th, 2021 /Newswire/ — Ampcera Inc., a pioneer in solid-state electrolyte manufacturing and next-generation solid-state battery development, announces that its all-solid-state battery (ASSB) technology has achieved a fast-charging milestone of 0 to 80% state of charge (SOC) in under 15 minutes at a peak C-rate of 4C. This advancement demonstrates the fast-charging potential of ASSB – a key requirement for the widespread adoption of electric vehicles (EVs).

Ampcera Announces its IP-protected Technology for Extreme Fast Charging All-Solid-State Batteries (ASSB)

Ampcera’s ASSB technology, which comprises IP-protected sulfide solid-state electrolyte materials, is engineered for extreme fast charging. A high-capacity NMC cathode and a silicon-based anode are used to achieve a high energy density goal of 400 Wh/kg. The ASSB is devoid of any liquid or semi-solid electrolyte ensuring the highest levels of battery safety, which is particularly crucial during rapid charging cycles.  Lab-scale pouch cells exhibited less than 5% capacity decay after 300 cycles of repeated fast charging (4C peak C-rate) demonstrating the potential for a long cycle life of greater than 1000 cycles in commercial cells once fully developed.

Ampcera’s high-performance solid-state electrolyte materials have propelled ASSB technology beyond the U.S. Department of Energy (DOE)’s ambitious fast-charging benchmark of achieving an 80% charge in under 15 minutes,” said Sumin Zhu, Co-Founder and CEO of Ampcera Inc. “Our primary objective is to introduce a commercially viable fast-charging ASSB technology that addresses consumer charge anxiety caused by extended wait times at charging stations.”
