For the cellphone user who goes through phones quickly and always needs a charge, Enlighten's Better Re lets you get some more use out of your old phone's battery, by allowing it to slot into an adjustable external battery charger for your new phone.
-
Dendrites – thin conductive filaments that form inside lithium batteries – reduce the life of these cells and are often responsible for them catching fire. Now researchers claim to have produced an electrolyte that completely eliminates them while also boosting carrying capacity and efficiency.
-
Researchers at Lawrence Berkeley Lab have invented an advanced lithium/sulfur (Li/S) cell that offers a unique combination of energy storage, power, recharge speed, and survivability.
-
Researchers at the University of Maryland are developing a cheap, long-lasting and environmentally-friendly sodium-ion battery using wood fibers.
-
Engineers at the University of California, San Diego, have developed new algorithms that improve the efficiency of existing lithium-ion batteries and could allow them to be charged twice as fast than is currently possible.
-
Researchers from the Tokyo University of Science have found pyrolyzed sucrose to be a surprisingly effective material for the anode of sodium-ion batteries.
-
An iron-air battery developed at USC appears a promising solution for large-scale storage of energy generated from intermittent renewable sources such as wind and solar.
-
The new Bosavi headlamp doubles as a lantern and a bike light.
-
The B&O PLAY Beolit 12 is about the size of a small car battery, weighs 2.8 kg and contains a substantial battery, a digital Class D 120 Watt amplifier, plus two 2" tweeters and a 4" woofer. It also plays seamlessly from IPad/iPhone via AirPlay
-
Two recent patent applications by Apple indicate the company is looking at developing a hydrogen fuel cell system that could potentially power portable electronic devices for "days or even weeks."
-
earthCell batteries are designed to be used like disposables, except that users send them away for recharging or recycling when they're used up.
