AllCell Granted U.S. Patent to Prevent Thermal Runaway Propagation in Li-ion Batteries
AllCell Technologies granted U.S. patent covering use of phase change materials to prevent thermal runaway propagation in Li-ion batteries, a critical requirement for large electric vehicle batteries.
Several recent high-profile incidents involving electric vehicle batteries have highlighted both the importance of battery safety and thermal management as well as the inadequacy of conventional thermal management strategies. Automakers are rapidly realizing that complex liquid cooling systems add significant expense, reduce vehicle range, and are prone to leaks or other malfunctions that can compromise battery safety and performance. Manufacturers of smaller electric vehicles such as electric bicycles, scooters, and motorcycles similarly struggle to manage the thermal demands of increasingly energy dense batteries with high discharge rates. AllCell’
One of the benefits of passive thermal management is the ability to operate even when the vehicle is turned off. Whether protecting car batteries parked all day in the scorching Phoenix sun or electric bike batteries baking inside a metal case exposed to direct sunlight, AllCell’s PCM composite can protect the expensive lithium-ion battery cells from overheating, dramatically extending battery life.
According to AllCell CEO Said Al-Hallaj, “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, created to commercialize PCM technology in automotive applications. The AllCell Automotive team is already working closely with leading automotive OEMs and is developing a new generation of automotive lithium-ion batteries with PCM thermal management technology that will be introduced soon.
