A lithium ion micro-battery out of the University of Illinois is just millimeters in size, can jump-start a car battery, and recharges in less than a second. It's not ready for market just yet, though.
Researchers at Northwestern University redesign the lithium ion battery to charge faster and increase energy capacity, paving the way for better battery performance on our gadgets.
Researchers at Northwestern predict a battery that will have 10 times the capacity and charge 10 times faster, while Argonne National Laboratory predicts a cell phone that can charge in a minute.
In ongoing research with children and adults, an Oxford University researcher finds that stimulating the brain with low-dose electrical currents could help improve learning.
Battery life on smartphones is generally terrible, and everyone knows it. Here's why, and who is trying to fix it.
Scientists with the Department of Energy have designed a new type of battery that they say outpaces the ubiquitous lithium-ion batteries in flammability, cost, and ability to hold a charge.
Two newly published patent applications describe curved and non-rectangular batteries that could better fit into portable electronic devices.
Company plans to use the funds to support its plan to build a cheap battery for bulk storage of wind and solar power.
If you're trying to figure out what your iPhone 5 (or 6) -- or your next Android device or Windows Phone -- is going to look like, there are some things you need to know.
Liquid Metal Battery, which aims to build a cheap battery for bulk storage of wind and solar power, hires its first chief executive and plans to raise more money.
