AllCell Technologies

AllCell Technologies designs and manufactures lithium-ion battery packs for portable, stationary, and transportation applications. Our patented thermal management technology allows production of compact, lightweight, and long-lasting batteries. AllCell’s thermal management technology is based on the use of phase change materials (PCM) to surround each lithium-ion cell, absorbing and conducting heat away to dramatically extend the life of the cells and prevent fire or damage to the battery. AllCell’s products avoid the need for expensive, complicated, and inefficient active thermal management systems, replacing pumps, motors, and hoses with an elegant passive system that requires no energy to operate and has no moving parts.

AllCell produces several lines of standard batteries and also collaborates with our customers to design, test, and manufacture high-quality custom batteries for a wide variety of applications. Funded in part by a generous grant from the State of Illinois, AllCell recently completed an expansion of our production facility in Chicago that allows us to economically produce batteries in both large and small lot sizes.
