Arizona State University's spin off outfit Fluidic Energy plans to build a new battery with an energy density 11 times greater than that of lithium-ion batteries for just one-third the cost.

Fluidic Energy uses ionic liquids as its electrolyte, which could help it overcome some significant problems faced by previous metal-air batteries. Currently metal-air batteries have usually used water-based electrolytes, but due to water evaporation, the batteries tended to fail prematurely.

It sucks that batteries are nearly bigger than the gadgets they're powering, but thanks to University of Missouri researchers and some tiny nuclear batteries, that'll one day be an issue of the past. Yeah, you read right. Tiny. Nuclear. Batteries.

The real secret behind the size of the batteries is the use of new liquid semiconductors instead of tired old solid semiconductors. That's great, because nuclear batteries aren't a new idea, nor are they terrifying and harmful according to Jae Kwon, assistant professor of electrical and computer engineering at the University of Missouri:

The Casio EX-Z60 Camera battery continues to fail. The camera itself is not bad, but once the battery is discharged or runs low it can't be changed again. Obviously these batteries are defective. Please post if you are having the same issue. CLICK HERE TO WATCH THE VIDEO

UPDATE: I called Casio about this battery issue and they informed me that the older defective batteries have now been replaced. According to them the new batteries will not fail. I'll let everyone know.
