Scientists double the capacity of rechargeable batteries

New research results presented today could bring companies such as Intel much closer to that goal of offering notebooks that achieve a battery running time of 8 hours and more.

Researchers of the Department of Energy's Argonne National Laboratory claim to have developed an enhanced approach to building of rechargeable lithium-ion batteries.

Scheduled for an unveiling at the meeting of the Electrochemical Society today, the new technology is based on a "manganese-rich" nano-crystalline, layered-composite structure that is used as material for the positive electrode. According to an early announcement, the researchers are using a uses a two-component "composite" structure: An active component for charge storage is embedded in an inactive component that stabilizes the structure.
