Researchers Create Battery that Can Charge in Seconds
A team of researchers at MIT have come up with a new way to recharge lithium ion batteries that could allow them to charge in seconds or minutes rather than hours. As lithium ion batteries act today, the ions need to travel through microscopic tunnels to create the charge. If the ions aren't correctly positioned near the mouth of the tunnels, they don't enter the tunnel and can't produce a charge. The MIT researchers have essentially created an easier way for the ions to reach and enter these tunnels, which they are calling a "beltway". This method for charging means batteries don't lose their capacity to charge over time. It also allows for faster charging, and smaller batteries that carry the same capacity. Smaller batteries can lead to smaller, lighter battery-powered devices.
Scientists Cook Up Quick-Charging Aluminum Battery
Aluminum-ion batteries may replace lithium-ion batteries in mobile devices thanks to a breakthrough made by U.S. researchers.
Oppo Talks Up Sensor-Based Image Stabilization
Oppo today debuted two new technologies at Mobile World Congress in Barcelona, one that promises higher-quality pictures and another that delivers faster-charging batteries. Oppo says it has created the first image stabilization system for phones at the sensor level.
MIT Spinout Claims to Double Battery Life
A company called SolidEnergy Systems, a spinout from MIT, says it has new battery technology that will double the life of lithium-based power cells. The breakthrough involves a battery that replaces the traditional graphite anode with a thin, lithium-metal foil.
Gold Wires and Electrolyte Gel Improve Battery Longevity
Researchers at the University of California at Irvine say they've found a way to increase the number of charge cycles a battery has from a few thousand to more than 200,000. Their discovery could lead to batteries that can be recharged repeatedly for years without losing capacity, which his something that happens with today's lithium-ion batteries.
The smaller battery with the same charge is also important for automobiles.
y cant they do this on cellphone?
15minutes AA/AAA charger.

lets hope not.
i'm really excited to see how this pans out. a battery like that would change my life.
no more problems with worn out batters
