Battery technology has long been considered the Achilles heal of modern gadgetry

The catch, (yes there's always a catch), is that in its current state of development the battery becomes unusable after only 40 to 50 charge cycles. Li-ion by comparison can typically handle anywhere from 300 to 500 full discharges. This is a pretty major caveat, and likely means it will still be quite awhile before this starts getting commercialized.

The real breakthrough with lithium-sulfur is the silicon nanowire technology which has actually been experimented with by Stanford engineers since late 2007. The new batteries are being described not just as more powerful, but safer too.

I can live with the short life if they are cheap. What I mean is if these batteries cost like $10 Dollars US for a pack 6 or even 4. But of course these are going to be for those custom cells that come in odd shapes for small devices. Still if the replacement is only like $10 bucks then I can handle buying a new battery every month or so for the privilege of having a battery that lets me run a laptop at full swing all day.

Right now, with an increase of 80% over Li-ion batteries, the charge limit could be almost ignored in certain applications. I'm thinking long-range military and scientific instruments, remotely located temporary installations, etc. The charge limit would be a major crutch to consumer electronics, but in certain applications the charging capacity would more than easily make up for the charge limit.

Battery technology has long been considered the Achilles heal of modern gadgetry, but the smart folks over at Stanford may just be on track to solve the issue. A new battery type is in the works called "lithium-sulfur" which currently offers an 80 percent improvement in capacity over Li-ion, and promises a theoretical increase of up to 400 percent as the technology matures.
