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.
Researchers Devise Fire-Resistant Battery
Jan 18, 2017
Adding a flame-retardant to select elements of lithium ion batteries many prevent fires, according to researchers at Stanford University. The researchers figured out how to create a nonwoven electrospun separator out of triphenyl phosphate and coated it with a heat-activated polymer.
MIT Spinout Claims to Double Battery Life
Aug 19, 2016
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.
Samsung Says Graphene Balls Help Batteries Charge Quicker
Nov 29, 2017
Samsung researchers believe graphene balls can make significant improvements to lithium ion batteries. The nano coating delivers a number of benefits.
LG Announces the V30 Flagship with FullVision Display and Floating Info Bar
Aug 31, 2017
LG today fully revealed the V30, a phone it has been teasing in bits and pieces over the last few weeks. This flagship-class handset has a metal frame and glass front and rear panels.
Gold Wires and Electrolyte Gel Improve Battery Longevity
Apr 22, 2016
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.

"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.
