This is an April 20, 2021 article about the sudden appearance of ‘Factorial Energy’ in the race to produce an ASSB using a proprietary polymer separator

Battery Startup Comes Out of Stealth to Seize On Investor Frenzy - Bloomberg

QuatumScape is mentioned a couple times in the article.

There are five metrics on which a battery is judged:
  • how much energy it packs,
  • how fast it charges,
  • how many charge-discharge cycles it lasts,
  • how safe it is, and
  • how much it costs.
Factorial’s current batteries reach energy density of 350 watt-hours per kilogram and 770 watt-hours per liter. The company’s aim is to reach 400 Wh/kg and 1,000 Wh/l.. But not much better than existing L-ion technology

Factorial’s battery can do up to 460 charge-discharge cycles before its capacity falls below 80%. That’s more than what Solid Power promises with 250 cycles, but less than QuantumScape at 800 cycles.

It looks like QuantumScape, has the a very big war chest with $1.5 billion compared to the other ASSB startups.

Factorial started internally testing batteries with 40 amp-hours of capacity, about 10 times the size of a smartphone battery. That’s double the 20 Ah battery that Solid Power has built and many times the size of the largest battery QuantumScape has disclosed.
(The size of a QuantumScape’s disclosed battery does not bother me too much since the industry is very secretive about their research. CARKEY)

solid-state battery partnerships:
  • Toyota Corp. is working with Panasonic,
  • Volkswagen AG with QuantumScape,
  • General Motors Co. with Solid Energy Systems,
  • Ford Motor Co. with Solid Power and
  • Mercedes Benz AG with Hydro Quebec
Solid-state batteries are set to see rapid increase in demand after 2030, eventually outpacing current lithium-ion batteries
