Ecellix

Ecellix is a materials science and medtech company based in Seattle, Washington, specializing in the development of high-capacity silicon-dominant anode materials for lithium-ion batteries. The company's proprietary e-Si® technology aims to replace traditional graphite anodes, offering up to three times the capacity and significantly improving energy density. While its technology has broad applications in consumer electronics and electric vehicles, Ecellix specifically targets the medical device market, providing longer-lasting and smaller power sources for wearables and implantable devices. The company was founded by renowned semiconductor pioneer Jerry S. Woodall and focuses on commercializing porous silicon-carbon composite materials that address the expansion issues typically associated with silicon anodes.
