Researchers Claim Lithium Battery Breakthrough
Scientists at Stanford University believe they have solved one of the major issues facing lithium battery technology. The researchers contend a pure lithium battery is best. "Of all the materials that one might use in an anode, lithium has the greatest potential. Some call it the Holy Grail," said Stanford Professor Yi Cui. "It is very lightweight and it has the highest energy density. You get more power per volume and weight, leading to lighter, smaller batteries with more power." The problem, however, is that lithium anodes form dendritic and mossy metal deposits that can cause batteries to crack, lose ions, and possibly ignite fires. In order to solve this problem, the researchers coated the lithium anode with a monolayer of interconnected amorphous hollow carbon nanospheres. The researchers say this helps isolate the lithium metal depositions and stabilizes the battery entirely. "The ideal protective layer for a lithium metal anode needs to be chemically stable to protect against the chemical reactions with the electrolyte and mechanically strong to withstand the expansion of the lithium during charge," said Cui. The solution could apply to lithium batteries used in smartphones, tablets, laptops, and even cars, vastly extending battery life.
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.
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.
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.
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.
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.
If we apply the same logic to the electronic version of powering devices, the common battery will remain fairly unchanged in order to keep profits and revenue sustainable through recirculation of sales. The Fortune500 has a nasty habit of controlling what makes it to market and what gets lost. As smartphones become more powerful and diverse, the increase in battery output will only grow to match what we see today. It will be up to the manufacturerd of the devices to find ways to compensate. Just as cars have for many years.
