Technology
One material that cools heat — then blocks fire
Thermorphous® is our adaptive platform. It conducts heat to keep batteries efficient in normal use, then transforms into a fire-protection insulator when a fault pushes temperature past a threshold — resolving the conductor-vs-insulator dilemma that causes battery fires.
The dilemma we solve
Battery fires persist because engineers are forced to choose between two materials that each solve only half the problem.
Option A
Heat-conduction material
Cools the cells — but offers no fire protection when a cell fails.
Option B
Heat-insulation material
Blocks fire — but traps heat and hurts efficiency and battery life in normal use.
Thermorphous
Both, in one material
Conducts heat below the threshold; foams into a fire-protection insulator above ~120 °C. No compromise.
How Thermorphous® works
At normal battery operating temperatures, Thermorphous® is thermally conductive — placed between cells, it dissipates heat to maintain efficiency and long battery life. Should a cell overheat above roughly 120 °C, the material transforms and foams into an excellent thermal insulator, providing fire protection that prevents high temperature from spreading to adjacent cells. It can withstand up to 1000 °C should the incident escalate into a thermal runaway.
This adaptive, two-in-one behaviour is protected by a patent portfolio (patent pending: US 18/565447, EP 4347718, CN 202280046769X, JP 100107456).

Across typical thermal-runaway barrier materials (aerogel, mica, composite fabrics) and thermal-interface materials (phase-change materials, thermal fluids), the Thermorphous® family spans a wide performance envelope — from thermally conductive below the transition to a barrier rated up to 1500 °C. In UL2596 backside-temperature testing, Pyrowerkz held a lower and more stable temperature than mica sheet, composite fabric and aerogel over a 30-minute exposure.
