Batteries

P&G announces plans to spin off Duracell.

Better batteries are the key to better consumer electronics and electric cars.

Tesla is relying on fab efficiency to cut prices on an established type of battery.

A group founded by angel investors seeks efficiency in developing new batteries.

Batteries are hard to develop because they live in the world of material science.

One challenge facing consumer electronics makers is the need for batteries that hold a longer charge.

At MIT, a scientist is studying sea snails, and say they hold the key to "biologically inspired processing."

They charge up hundreds of times faster than a battery, never wear out and need replacing, and they don’t care about temperature extremes.

The company Better Place is liquidating, after a failed attempt to make electric cars with batteries to swap in and out. Problem is, e-vehicles are still expensive. And fossil fuel prices in the recent downturn have softened.
