Definition
The term, in context
AI-assisted draft · approved dataset
QuantumScape's QSE-5 is a solid-state lithium-metal battery cell that replaces the graphite anode with a ceramic separator and an anode-free lithium-metal design to raise energy density and shorten charge times, while the Cobra process is a manufacturing method for producing that ceramic separator through a rapid, high-throughput heat-treatment step instead of a slow furnace bake.
