Battery life has one of the biggest complaints by users of portable devices. Consumers are demanding more features on their cell phones, notebook pcs, cameras, etc. All of which consume more power. The device manufacturers are caught in the middle – trying to minimize power consumption by the various applications while providing the new features consumers are demanding.

Up until now, battery technology has been unable to bridge the power gap being created in portable consumer electronic products. Sion Power’s Lithium Sulfur technology can be the solution to many of the energy gap problems. The chart below compares the theoretical values for both specific energy and energy density for Li –S and lithium ion batteries. Lithium ion is the most widely used battery chemistry in consumer electronics today.


Sion’s Li-S gives the manufacturer options that have not been available from batteries for some time. Today, the best lithium ion cells are at 220 WH/Kg. Sion’s Li-S is over 350 WH/Kg. This means 50% longer run time with no weight penalty. On the manufacturer can reduce the weight of the device and maintain the current run time.

With over 4 times the specific energy and 45% greater energy density, Li-S is the clear choice to bridge the energy gap that exists in portable consumer electronics today.
