QuantumScape is developing next-generation solid-state lithium-metal batteries designed to deliver higher energy density, faster charging, and improved safety by replacing the flammable polymer separator with a thin, non-combustible ceramic separator. For OEMs and Tier-1s, this architecture reframes battery thermal management: higher power demands and rapid charging increase heat flux, while the solid-state design aims to mitigate thermal-runaway risk and simplify safety engineering at the pack level.

With a cell format and manufacturing toolkit built specifically for lithium-metal, QuantumScape integrates heat paths and pressure management at the cell—not only the pack—while scaling separator production to automotive volumes. Recent safety testing on 24-layer prototype cells shows Hazard Level 3 (minor venting) even when heated to 300°C, underscoring the technology’s thermal stability under abuse compared with conventional Li-ion.

Key Technologies Supporting EV Battery Systems:
FlexFrame™ Cell Format
Engineered hybrid pouch/prismatic cell with a rigid perimeter frame and flexible faces to route heat laterally for efficient side/back cooling—supporting fast-charge heat rejection and operation with or without external pressure for pack integration.

Ceramic Solid-Electrolyte Separator
Non-combustible separator chemically isolates anode and cathode; in heated-cell abuse tests to 300°C, QS’s 24-layer prototypes achieved EUCAR Hazard Level 3, indicating improved thermal stability versus conventional Li-ion.

Cobra™ Separator Process
Next-generation ceramic-separator manufacturing that delivers ~25× faster heat-treatment versus the prior “Raptor” process, shrinking equipment footprint—critical to scaling solid-state cells cost-effectively.

Low-Temperature Performance
Reported capacity retention down to −30°C reduces reliance on heavy pre-heating strategies and helps maintain drivability in winter conditions—key for BMS thermal logic and customer range expectations.

Whether in thermal architecture, battery management, or systems integration, QuantumScape’s innovations—FlexFrame, a non-combustible ceramic separator, and the high-throughput Cobra process—target the core challenges of lithium-metal batteries: heat dissipation during fast charge, uniform temperature control, safety under abuse, and manufacturability at scale.

NeoGraf Solutions supplies advanced flexible graphite materials that move heat fast, even in thin, lightweight formats—helping OEMs and Tier 1s tame hotspots, improve uniformity, and slow thermal propagation in EV packs.

NeoNxGen™ Thick Flexible Graphite
Single-layer, high-performance graphite (UL 94 V-0) for “thick” heat paths, shields, and fin geometries where multiple layers were once required—simplifying assembly while sustaining ~900–1100 W/m·K in-plane conduction.

GrafGuard® Expandable Graphite (Fire Protection)
Non-halogenated, intumescent graphite additive for foams, coatings, and barrier walls that forms a char layer, absorbs heat, and displaces oxygen—supporting pack-level fire-protection strategies without melamine-based FRs.
