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.

last i heard, this lithium-manganese chemistry is alot more stable than the old lithium polymer... ive got some experience in radio controlled models and we use similar batteries, apparently these li-mn batteries still work if you shove a metal rod right through it... and theyre alot more forgiving if you overcharge/undercharge them etc etc, as far as i can remember anyway

My friend's HP computer has 16 hours of battery life, and about 9 when gaming.

News isn't that "new". (Unless 16 hrs becomes 32 hrs)

"goal of offering notebooks that achieve a battery running time of 8 hours and more. "

And the explosive power of a small nuke... :nuts:

Wasn't there an article just days ago about Acer saying no new battery improvements in the near future? Kinda funny to read this today...

So why would they want to go this route instead of straight to the also nano-tech based capacitors announced by a couple of research teams a few months back?
Other than purely because a 2x the use time doesn't mean the overall lifetime of the battery increases much if any, and capacitors will mess with their repeat sale model significantly.

Bingo, all about money, who cares about actual advancement.

The best part: "It was unclear if and when the technology could go into mass production."
