Batteries stories

Lithium, the element that is often used as a medication to battle bi-polar disorder and to power most laptop and phone batteries, is not the most ubiquitous element on the planet. Hence the price of our batteries. Japanese researchers, though, may have discovered a way to use sugar to power batteries.
Here's an absolutely brilliant idea from Apple: imagine if you had a bunch of different gadgets, and imagine if they could all somehow be powered by batteries that were rechargeable and all interchangeable with one another. How awesome would that be? Super awesome! If only we'd thought of it a long time ago.
There are two necessary evils that we despise about gadgets: the need for batteries, and the need for cables. LG Chem has now come up with a way to combine both cables and batteries into one thing (a "batterble," if you will) that's a full 50% less evil. It's not quite good, but it's way better than what we've got now.
Ah yes, another amazing battery technology guaranteed to make everything from electric cars to cell phones charge instantly. This one comes from boffins in South Korea, who have added carbon networks to lithium-ion batteries to make them charge anywhere from 30x to 120x faster.
Carbon nanotubes have promised some incredible advances in power efficiency, but one of the most promising (and most realistic) is boosting the capacity of lithium-ion batteries by a factor of two in the near term, and eventually by five. Suddenly, your electronics that last all day will be lasting all week instead.
