GRAFX™ THERMAL TECHNOLOGY
GrafX™ is an advanced thermal-management technology platform designed to spread localized heat, buffer transient thermal loads and improve temperature uniformity in high-performance battery systems.
By combining highly conductive thermal structures with phase-change thermal buffering, GrafX™ can be engineered around different battery architectures and thermal requirements.
THE THERMAL CHALLENGE
Managing Heat Where High-Power Batteries Need It Most
High-power battery operation can create localized hotspots, temperature gradients and transient thermal loads. Effective thermal architecture is therefore an important part of battery-system design.
OUR THERMAL TECHNOLOGY
Introducing GrafX™
Engineered to Manage Thermal Energy.
GrafX™ is a thermal-management technology platform incorporating graphite-PCM composite materials and engineered thermal architectures.
With multiple material configurations and form factors, GrafX™ can be engineered to meet specific thermal, mechanical and integration requirements.
HOW GRAFX™ WORKS
From Localized Heat to More Uniform Temperature
GrafX™ surrounds selected battery cells with a highly conductive thermal structure and phase-change material (PCM) to spread localized heat and buffer transient thermal loads.
01 — LOCALIZED HEAT
During high-power operation, localized heat can generate thermal hotspots across battery cells.
02 — GRAFX™ SPREADS AND BUFFERS HEAT
The GrafX™ structure provides a highly conductive pathway for lateral heat spreading while phase-change material helps absorb and buffer transient thermal loads.
03 — MORE UNIFORM TEMPERATURE
The objective is a more uniform temperature distribution across the cells and battery structure, reducing thermal gradients during demanding operation.
BATTERY INTEGRATION
Engineered Around Different Battery Architectures
GrafX™ can be configured around different cell geometries and pack architectures to address localized thermal loading and temperature non-uniformity.
