Sion Power Corp. is a 35-year-old, vertically integrated battery technology company with full design, build, test, and validation capabilities. Headquartered in Tucson, Arizona, we are advancing the future of energy storage with our proprietary, patented Licerion® technology.



Licerion® tackles the biggest barriers to mass EV adoption: range, cost, and charge time. We do this by minimizing dendrite formation by solving the primary failure mode of lithium-metal batteries. Our breakthrough approach unlocks the true potential of lithium metal, delivering twice the energy density of traditional lithium-ion and leapfrogging graphite and silicon anode solutions.



Sion Power holds nearly 500 patents issued and pending, with over 90 employees focused on bringing Licerion® to volume production by 2028.
