Discharge capacity (left axis) and Coulombic efficiency (right axis) of the Li 2 S-C cathode as a function of cycle number. Lithium sulfide (Li 2 S) is a promising cathode material for high-energy lithium ion batteries because, unlike elemental sulfur, it obviates the need for metallic lithium anodes. Click to enlarge.

The award is co-funded by the US Department of Energy (DOE) and includes a 50% cost-share by Leyden Energy. The focus of the 16-month program is to develop an advanced lithium-ion 12-volt start-stop battery system to meet or exceed the performance, life and cost targets set by USABC. Source: USABC.

Measurements also indicate that these new materials could yield a cathode that is extremely energy-efficient. However, transition metal fluorides, which contain the element fluorine plus one or more of the transition metals, such as iron and copper, have much higher ion-storage capacities than traditional cathodes.
