Could this be the end for batteries? Scientists generate electric power from Wi-Fi

A flexible material that converts radio signals into usable electric current raises the prospect of a world without batteries. Scientists in the US developed the device, known as a “rectenna”, from a semiconductor just a few atoms thick. Wi-fi signals captured by an integrated antenna are transformed into a DC current suitable for electronic circuits.…

Batteries to charge up in less than 20 secs

I always thought that a whole new battery technology would be the way to enhance our mobile power supply experience of techno-gadgetry, but it turns out it’s going to be good old Li-ion all along. Apparently, we’ve been doing it wrong all this time and that we’ll have one that can charge up in less than 20 seconds in two to three years’ time.

We know this because a crack team of battery bods at MIT has already…

BATTERY DEVELOPMENTS: Korean scientist claims eight-fold leap in power-up time

It is a bit of a shame and quite an embarrassment for mankind that batteries haven’t come on in leaps or bounds since the 1970s, with modern Duracells only being marginally better than the Duracells used to power a Big-Trak for about 35 minutes on Christmas Day, 1981.

But that might possibly be about to change – thanks to a man called Prof. Cho Jae-phil who works at the Department of Applied Chemistry at Hanyang University, in South Korea…

Toshiba SCiB battery could start a revolution, assuming the revolving mechanism is battery powered

Toshiba is apparently in the process of inventing and testing a revolutionary new type of battery, that it claims will be available next year. Bankrolled by it’s “utopian dreams” division (headquarters in fantasyland), it has apparently come up with a battery that fixes all of the problems that normal batteries have…
