GrafX: Thermal Management System (TMS)

GrafX is a versatile composite material primarily made of Graphite and PCM (Phase Change Material). GrafX has very high thermal conductivity and heat storage capacity that can be customised upto 80 W/m.K by changing the material properties.

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.


Lithium Battery using GrafX successfully passed AIS-156 (Phase-2, Amendment 3) for Electric 2W applications

Our first customer has successfully passed AIS-156 (Phase-2, Amendment 3) Certification testing, including Thermal Propagation Test using CaloryTech’s GrafX thermal management system and is starting production in May 2024. CaloryTech has collaborated with one of the leading Lithium-ion battery and 2-Wheeler EV manufacturer to incorporate GrafX in their battery packs for electric 2W vehicles.

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 Heat Storage Capacity up to 260 kJ/kg
  • 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

CaloryTech has established strategic relationships with battery contract manufacturers in Bangalore, Hyderabad, and Chennai to serve our customers across India to design and assemble battery packs incorporating our thermal management system GrafX at competitive rates. CaloryTech can work very closely with battery OEMs or startup companies to design and assemble Lithium-ion battery packs integrated with smart BMS and GrafX TMS.
