Based on new, highly active nanoscale material initially developed at MIT, A123Systems' low impedance Nanophosphate electrode technology provides a competitive advantage over alternative high power technologies. A123's cell and electrode designs lower cost/watt and cost/watt-hour. They have higher voltage than other long-life systems, enabling lower pack cost. Their long life leads to reduced lifecycle and system costs resulting in greater overall price-performance . Competitors include [Valence](http://www.valence.com), [Saft](http://www.saftbatteries.com) and [Lion Cells](http://www.lioncells.com).
