Depressing Truth About Battery Technology

Depressing Truth About Battery Technology | cross pond high tech | Scoop.it

While computing power has taken off, battery life has languished as evidenced in a 2005 report by Joseph A. Paradiso of MIT.

Christopher Mims republished the chart today at Quartz. Mims asked if there was an update to the chart.

 

He was told there was no update.

California teen invents device that could charge a cell phone in 20 seconds

California teen invents device that could charge a cell phone in 20 seconds | cross pond high tech | Scoop.it

Eesha Khare is the mind behind a super-powerful and tiny gizmo that packs more energy into a small space, delivers a charge more quickly, and holds that charge longer than the typical battery. Khare showed off her so-called super-capacitor last week at the Intel International Science and Engineering Fair in Phoenix, Ariz. In her demonstration, she showed it powering a light-emitting diode, or LED light, but the itty-bitty device could fit inside cell phone batteries, delivering a full charge in 20-30 seconds. It takes several hours for the average cell phone to fully charge.

Khare also pointed out that the super-capacitor “can last for 10,000 charge cycles compared to batteries which are good for only 1,000 cycles.”

Philippe J DEWOST's insight:

Most of us have been dreaming of this at some point, right?
