GrafX: Thermal Management System (TMS)

GrafX is a versatile composite material made of Graphite and PCM (Phase Change Material). GrafX is very suitable as a passive cooling system to address thermal management problems in numerous applications such as Lithium-ion batteries, drones, portable electronic systems such as smartphones, tablets and other demanding applications.

CaloryTech has worked with a Lithium-ion battery OEM company in India to help them successfully pass Thermal Propagation Test as part of the AIS-156 (Phase-2, Amendment 3) certification using GrafX thermal management system for electric 2W application.

To design and deliver the innovative products.

Advantages of GrafX

  • Enables Fast Charging and Fast Discharging of battery packs with faster heat removal
  • Enables your battery to easily pass AIS - 156 (Phase 2, Amendment 3) thermal propagation test
  • High thermal conductivity (15 to 20 W/m-k) & low-weight compared to potting material, wax, other PCMs
  • High Latent Heat (220-240 kJ/kg) and Specific Heat (2.1 to 2.4 kJ/kg-K) compared to potting material, thermal pads, and wax
  • Substantially improves battery safety - offers 24x7 Thermal Runaway Protection
  • Long Lasting Batteries: keeps cells cooler even in hot summer, thus extending battery calendar life
  • Requires no external power, easy to install and compact design for cylindrical, prismatic or pouch cells

Lithium-ion Batteries with Smart BMS and GrafX TMS
