What Holds Energy Tech Back? The Battery

Washington (AP) -

As 21st century technology strains to become ever faster, cleaner and cheaper, an invention from more than 200 years ago keeps holding it back. It’s why electric cars aren’t clogging the roads and why Boeing’s new ultra-efficient 787 Dreamliners aren’t flying high.

And chances are you have this little invention next to you right now and probably have has a problem with it recently: the infernal battery.

Boeing is the first company to make extensive use in an airliner of technology’s most advanced battery — lithium ion. But a Jan. 7 battery fire aboard a Dreamliner in Boston, followed by a similar meltdown in Japan, led authorities around the world to ground the fleet this month, highlighting a longstanding safety problem that engineers have struggled with.

In 2006 and 2007, more than 46 million cellphone batteries and 10 million laptop batteries — all lithium ion — were recalled because of the risk of overheating, short-circuiting and exploding. Additional safety features have been installed since then on lithium ion batteries used in consumer electronics.
