Energy Density, ~350 Wh/kg (Targeted/Modelled)., ~301 Wh/kg (Validated B-sample).
Safety Level, EUCAR 3 (Passes nail penetration, High (Ceramic separator is non-flammable).
with no fire/explosion).,

Quantumscape mcap: $4.26 billion
Ilika mcap: £52 million
Verdict:
"In terms of "Science": It’s a tie. QuantumScape’s lithium-metal tech is more "ambitious," but Ilika’s oxide-silicon tech is more "practical."
In terms of "Progress": QuantumScape is one step ahead in the automotive sampling process (B-samples vs. Ilika’s late A-samples).
In terms of "Business Model": Ilika is arguably "closer" to profit because they don't need to spend billions on factories to win; they just need one major licensing deal."
