Sion Power’s Li-S batteries have the potential to be an enabling technology for both Plug In Hyrid and Pure Electric Vehicles. With over 350 Wh/Kg today, this exceeds most manufacturers’ expectations for specific energy for a vehicle battery. The chart below clearly demonstrates why Li-S is the key to a successful electric vehicle battery:

(The 54 kWh packs is based on using SION’s 350 WH/Kg technology while the 70 kWh pack is using the next generation of cells that are at 450 WH/Kg.)
Not only does Li-S improve the driving range of the vehicle, it improves the overall payload capability. With a compromise between the battery volume and battery weight, a SION Power Li-S vehicle battery pack can achieve one of the primary goals set forth by auto makers – a 300 mile driving range. It is easy to see why SION Power’s Li-S batteries are the future power source for electric vehicles.
