Solid Power DCRC+
О
Polymer
■ Small temperature performance
range requiring additional
heating
■ Flexible and elastic
Easy to process
"
Conductivity an order of
magnitude lower than sulfide
Rigid and brittle
■ Ceramics require complex and
hard to scale sintering
■ Not practical for catholyte
Sulfide
Highest ionic conductivity;
comparable to liquid electrolytes
Compressible at room

■ Stable up to 120 °C
May require pack-level cooling
■ Stable up to 500+ °C
■Stable up to 450 °C
■ Does not only conduct Li ions
which complicates Li plating
▪ Use water-reactive salts
Chemically stable but dendrite
prevention is a challenge
Requires surface coatings and/
or moisture free processing
Degradation hurts performance,
but no safety hazards
Composition must be designed
to create stable passivating
interface with Li metal
Moisture exposure forms H₂S
Bare-powder concern; easily-
controlled in manufacturing
▪ Limited reactivity in cells
Sulfides offer the best balance of
performance and mass production
