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.
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.
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.
Gold Wires and Electrolyte Gel Improve Battery Longevity
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.
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...
