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. Scientists have long sought to use aluminum in batteries because it is relatively inexpensive and light weight. They discovered that using aluminum as the negative anode and graphite as the positive cathode works very well. The aluminum-ion prototype battery can be fully charged in as little as one minute and can last through 7,500 charge cycles — more than seven times that of today's lithium-ion batteries. Furthermore, aluminum is much more stable and therefore safer than lithium-ion. "Lithium-ion batteries can be a fire hazard," said Hongjie Dai at Stanford University in California. "Our new battery won't catch fire, even if you drill through it." The aluminum-ion battery is durable and can be bent or folded. The researchers did not say if the aluminum-ion battery matches lithium-ion in terms of charge capacity relative to size. There's no word on if or when aluminum-ion batteries might reach consumer devices.
Energizer Power Max P600S Has 2:1 Display, Huge Battery
French phone maker Avenir Telecom has licensed the Energizer brand for a range of large-battery phones, which it aims to bring to the U.S. by the end of the year.
AT&T's Latest GoPhone Runs On AA Batteries
AT&T today announced the SpareOne Emergency Phone, a simple handset meant purely to serve as a backup phone for critical situations. The SpareOne runs on AA batteries, rather than a rechargeable lithium-polymer power cell.
Samsung Researchers Make Battery Breakthrough
A research team working at Samsung has discovered a new way to make lithium-ion batteries that could double the available battery life in devices such as smartphones. The method involves covering silicon nanoparticles with graphene, which prevents the formation of silicon carbide.
LeEco Details the LePro3 with Snapdragon 821
LeEco today announced the LePro3 smartphone, an Android-based flagship that includes the Snapdragon 821 processor and a 4,070mAh battery. LeEco says the large power cell provides 33 hours of talk time or up to 49 hours o media playback.

"Our battery produces about half the voltage of a typical lithium battery," Prof Dai said. "But improving the cathode material could eventually increase the voltage and energy density."

However, just like the oil industry, sales are driven by repeated necessary evils. If the technology is significantly improved upon where no one needs to replace it as regularly as now, sales will diminish to the point of no revenue.
I honestly feel this is another development to that answers if it can be done. But, the question is, will it be done for mass adoption? Skeptical.
