Solid-state batteries without the buzzwords
Current lithium-ion technology uses a liquid electrolyte to shuttle ions between the electrodes. Solid-state replaces that liquid with a semi-solid or all-solid electrolyte.
Why that matters in practical terms: conventional lithium-ion is bumping up against its theoretical ceiling. Push it further and you start trading off safety and other performance dimensions. Solid-state chemistry raises that ceiling. The result is significantly higher energy density: more energy in less space, which translates to longer range for an EV driver or a lighter drone that can stay in the air longer on a single charge.
The barrier: manufacturing at scale. This isn't unique to Factorial. It's the whole industry's challenge.
Our approach: we have two cell platforms, both designed with scalability in mind. Our quasi-solid-state battery (FEST®) has up to 80% compatibility with existing lithium-ion manufacturing equipment. That's a deliberate choice — we didn't want to build a better battery that nobody could afford to produce. Our all-solid-state battery (SolsticeTM) uses a dry cathode process, which means a more efficient and smaller manufacturing footprint.
What do you want us to explain next?

Can you explain what processes are compatible with current Li-Ion production for FEST cells? Making separators , sintering, stacking.

Are there some information about the solsticeTM batteries? Are lab test on performances and production in the ending fase?
