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.
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.
Samsung Says Graphene Balls Help Batteries Charge Quicker
Samsung researchers believe graphene balls can make significant improvements to lithium ion batteries. The nano coating delivers a number of benefits.
Sony Hoping to Boost Battery Capacity By 40%
Sony is looking at sulfur to help improve the performance of rechargeable batteries. Sony says using sulfur as an electrode material can increase the energy density from today's limit of 700Wh/L to 1,000Wh/L.
Researchers Devise Fire-Resistant Battery
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.

"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.
