AllCell uses phase change materials to prevent Li-ion thermal runaway propagation

AllCell Technologies received a new US patent covering the use of phase change materials (PCM) to prevent thermal runaway propagation in electrochemical devices such as lithium-ion batteries.  AllCell has developed a proprietary composite material composed of a conductive matrix impregnated with various PCMs that extends the cycle life of lithium-ion cells and can prevent the propagation of thermal runaway.

AllCell’s thermal management technology uses phase change materials to surround each lithium-ion cell, absorbing and conducting heat away to extend the life of the cells and prevent fire or battery damage. The company points out that complex liquid cooling systems add expense, reduce vehicle range, and are prone to leaks. AllCell’s technology requires no power to operate, has no moving parts, and can operate even when the vehicle is turned off.

AllCell CEO Said Al-Hallaj said, “We are very pleased to announce this enhancement of our IP position during a period of rapid growth for our company.  AllCell is excited to contribute to the critical improvements in electric vehicle batteries required to transition from today’s limited market of early adopters to products with true mass market appeal.”

Earlier this year AllCell announced the formation of AllCell Automotive, a joint venture with Townsend Ventures, LLC, to commercialize PCM technology in automotive applications. The joint venture is working with automotive OEMs to develop a new generation of automotive lithium-ion batteries with PCM thermal management technology.
