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. First, batteries that make use of graphene balls are able to charge much faster. For example, a battery that normally takes 60 minutes to recharge would be able to recharge in just 12 minutes. It does this by suppressing detrimental side effects and providing charging pathways that are more efficient. Second, coating lithium ion in graphene creates batteries that are more dense, leading to higher-capacity batteries. Samsung says it can increase density by as much as 27.6%. Last, the graphene does not create any detriments to the number of charging cycles. For example, a battery with graphene balls will retain 78.6% of its capacity after 500 charging cycles. For now, Samsung is hoping to use this technology in batteries for electric vehicles. It may eventually be scaled down to batteries for mobile devices, but Samsung did not say if or when this technology might reach any consumer products.
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.
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.
