USA: PolyPlus lithium battery named one of top inventions for 2011

PolyPlus, a developer of high-energy, lithium metal batteries, has had its lithium battery named one of TIME Magazine’s 50 best inventions for 2011. The PolyPlus lithium battery uses ordinary seawater or air interacting with lithium to deliver unprecedented energy density levels in a non-toxic, environmentally friendly and inherently safe product.

An early innovator in battery technology and the inventor of lithium sulfur batteries, PolyPlus has developed a new technology, the Protected Lithium Electrode (PLE), which enables the creation of a new class of high-energy density batteries. Simply put, the lithium is encased in a special, patented membrane that allows it in to react with water or ambient air, depending on its configuration, to deliver its high-energy performance. Without the membrane, lithium reacts vigorously with water and rapidly dissolves, or rapidly oxidizes when exposed to air.
