New battery tech lasts for days, charges in seconds

Scientists from the University of Central Florida (UCF) have created a supercapacitor battery prototype that works like new even after being recharged 30,000 times. The research could yield high-capacity, ultra-fast-charging batteries that last over...

Army scientists juice battery voltage, hike life up to 30 percent

army-scientists-juice-battery-voltage-up-to-30-percent

With the modern US soldier turning into a walking gadget, the army has some heavy reasons to lower battery weights. Its own scientists might have the answer, claiming 30 percent energy density jumps could happen using additives they developed. Those "sacrificial agent" materials would bond with electrodes to allow five volts instead of the four they've been stuck on, permitting a "quantum leap" in efficiency and weight. We'll have to see if that'll come to pass, but given the sheer volume of tech that soldiers are strapping on these days, it couldn't be too soon. To see a video of how it works, zap past the break.
