Promises and Perils

For ages, the promise of an effective, safe solid-state battery has been the ultimate unattainable goal — ideal, enticing, but always out of reach.

Consider this quote:

“The storage battery is, in my opinion, a catchpenny, a sensation, a mechanism for swindling the public by stock companies.”

The speaker: Thomas Edison. The year: 1883.

138 years later, that sentiment has held true.

Factorial’s Solution

Factorial Energy has invested heavily in solid-state battery research and chemistry research over the past 6 years to create our proprietary Factorial Electrolyte System Technology (FEST®).

Our process is practical, customer-driven, and electrode agnostic, and has yielded  the world’s first commercial scale, balanced performance-profile solid-state cell.

The FEST® system, developed in conjunction with several of the world’s largest auto OEMs and cell manufacturers, delivers on the promises of solid-state performance without fatal defects found in iterations of the technology to date. The technology will debut in the high spec market as a proving ground for its performance and manufacturability.
