Researchers Make Lithium-Ion Batteries Safer
Researchers from Taiwan's Industrial Technology Research Institute have developed a new material that will make lithium-ion batteries safer to use in today's electronic devices. Li-ion batters are used in mobile phones, and there have been some instances where batteries overheated and caused fires and/or injuries. The cause of these fires is batteries that short circuit, most often due to damage. To prevent li-ion batteries from short circuiting, the researchers created a new polymer, called STOBA (self-terminated oligomers with hyper-branched architecture). This polymer is applied to the cathode material inside a li-on battery, which prevents the battery from short circuiting if it is damaged. The researchers say the material will add only 2% or 3% to the cost to manufacture the battery. The researchers say the material is ready for use, though no battery makers have publicly committed to using it.
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.
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.
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.
what a waste of time!
how often do you get batteries to explode or a fire?
I suppose only once because you would probably end up burning up with it. :-)
So they Won't Blow up in iPhones???
Am I the only one...
