Argonne Composite Battery

Researchers at Argonne National Laboratory in Argonne, IL claim to have developed composite battery materials that will increase battery life by up to 30 percent, as well as making them safer and last longer than conventional lithium-ion batteries. The new batteries, based on a new generation of lithium-ion electrode chemistry, are similar to the ones GM is developing for its Chevy Volt electric vehicle, but Argonne is likely to market its technology to extend the usefulness of laptops and cell phones.
