WSJ (link) is reporting that a company called StoreDot has developed a biological battery that can be charged in 30 seconds. The technology comes from the nanotechnology department of the university of Tel Aviv.

Fast chargers are nothing new but they are typically too big to be considered portable. StoreDot's technology is relative portable and can be adapted for use by almost any cellphone. The other benefit is cost. The company expects its technology to only cost twice the market price of a normal everyday charger. 

As exciting as all of this is, you can put your credit card away. The company doesn't expect to commercialize the product until 2016. 

This is one of the most exciting technologies I have seen in a while and I really hope they stay independent and built this for many smartphones (and not get snapped up by Apple or Samsung).
