Sion Power, a privately held company, was founded in 1989 as Moltech, a spin-off from Brookhaven National Laboratory, with a focus on research and development. Since then, the company has grown, attracting an impressive group of scientists, engineers, and partners who have worked to develop the required technology to create a next generation electric vehicle battery.

Today the company employs over 100 employees, many of whom have Ph.D.’s. This impressive group of individuals has acquired over 430 international patents and patent applications. The company’s 110,000-square-foot production and R&D facility includes a dry room for cell manufacturing, a robust safety and abuse testing lab, and over 2,000 test channels in a separate 5,300-square-foot test facility. Sion has state-of-the art analytical/materials, and electronic assembly labs.

Decades of research and development have yielded the Licerion® lithium metal technology, which is poised to dramatically change the lithium battery landscape.
