Sion Power is the global technical leader in the development and application of high energy, rechargeable lithium sulfur batteries.

Originally a spin off from Brookhaven National Laboratories, Sion Power has assembled an international team of scientists and engineers dedicated to developing the next generation of rechargeable batteries. By using the powerful combination of the elements, lithium and sulfur, in the most efficient geometry, a thin-film sandwich, Sion Power has created a rechargeable battery with advanced characteristics. Today, Sions lithium sulfur based cells exceed 350 Wh/Kg, over 50% greater than the best available battery technology in the market. Tomorrow, over 600 Wh/kg and 600 Wh/liter are possible with this system. Applications that will benefit from Sion's advanced Li-S battery technology include a light-weight portable power source for military use, extended run time batteries for cell phones, and the power supply to make electric vehicles a reality.
