Looking for a better lithium battery

The United States Environmental Protection Agency, and other science groups will be focusing on bringing manufacturers of "various types of lithium-ion batteries together". Together the manufacturers will try to create "environmentally sound manufacturing and material choices". Companies that use carbon nanotubes to make their lithium-ion batteries is their first order of business. They will be taking life cycle assessments of the various materials and processes needed to create lithium batteries to try to minimize the environmental impacts and risk to public health. By mid-2011, they hope to provide companies "with information on how to improve their extraction, manufacturing, and disposal practices [of lithium batteries]".
