Factorial Energy unveils 40 Ah solid-state EV battery cell

Factorial Energy has introduced what it says is the first 40 Ah solid-state EV battery cell. 

The Factorial Electrolyte System Technology (FEST) is a proprietary solid electrolyte material designed to enable safe and reliable cell performance with high-voltage and high-energy-density electrodes. Solid electrolytes like FEST are considered safer than conventional lithium-ion technology, as they replace the combustible liquid electrolyte with a more stable solid-state electrolyte that suppresses dendrite formation on lithium-metal anodes. 

“Factorial’s solid-state battery technology offers the performance, safety, scalability, and commercial readiness needed to move the needle of EV adoption. We are thrilled to be the first to reach the 40 Amp-hour benchmark for a solid-state cell,” said CEO Siyu Huang.

Factorial says several automotive partners are currently evaluating its technology, with the intent of integrating FEST into their existing supply chains.

“Our batteries are unique because they achieve the broadest range of OEM performance requirements while offering superior energy density, safety and scalability,” said Joe Taylor, Factorial’s new Executive Chairman. “Our technology can be easily integrated into existing lithium-ion battery manufacturing infrastructure, which makes Factorial an immediately viable partner for every automaker pursuing EVs.”
