Korean Professor Cho Jae-phil in the Department of Applied Chemistry at Hanyang University has developed a new cathode material that extends the "battery life" capacity of Lithium batteries 8 times the capacity of batteries currently made.

Batteries today are made using graphite whereas Jae-phil uses silicon to achieve the major increase in performance.

Lithium batteries are used in all laptop, cell phone and mobile electronics. This is a huge break for the future of mobile electronics.

2000 Lumens. Check. 20 lithium batteries. Check. Battery life of 1.5 hours. Check. Pricetag of $7000. Check. if you need to shine a light equivalent to 130 "normal" flashlights, then the Surefire Beast II LED is for you. I’m trying to think of an application for this monster, and I’m failing. But I’m sure there’s someone out there who needs more light than I do.
