\"\"<\/a>WASHINGTON \u2014 A newly created lithium-ion battery<\/a> that can heal itself may improve the life span and safety of today\u2019s energy-storage technologies, researchers report.<\/p>\n

\"sciencenews\"Rechargeable lithium-ion batteries<\/a> power cell phones, laptops and other portable electronics. But, like any batteries, they tend to break down over time.<\/p>\n

\u201cThere are many different types of degradation that happen, and fixing this degradation could help us make longer-lasting laptop batteries<\/a>,\u201d said Scott White, a materials engineer at the University of Illinois at Urbana-Champaign who reported the details of the battery Feb. 20 at a meeting of the American Association for the Advancement of Science.<\/p>\n

One site of damage is the anode, a battery\u2019s negatively charged terminal. As a Dell Latitude D620 Battery<\/a><\/strong> charges and discharges, the anode swells and shrinks. Over time, this cycling causes damage, creating cracks that can interfere with the flow of current and, ultimately, kill the Toshiba PA3534U-1BAS Battery<\/a> .<\/p>\n

To counteract this cracking, White embedded tiny microspheres inside the graphite of an anode. As cracks formed in the anode, they tore open the plastic shells, releasing the contents within: a material called indium gallium arsenide. This liquid metal alloy seeped out of the spheres and filled the cracks in the anode, restoring the flow of electricity.<\/p>\n

Damage to a battery<\/a> \u2014 or a short circuit between its components \u2014 can cause problems other than a shorter life span. Out-of-control electrical currents have been known to create hot spots that grow into a raging fire.<\/p>\n

\u201cIt\u2019s not a common occurrence, but when it happens, the consequences are severe,\u201d White said. Battery fires have prompted laptop recalls by Dell<\/strong><\/a> and Hewlett-Packard, and the U.S. Department of Transportation has proposed stricter rules for cargo planes that transport large quantities of lithium-ion HP laptop batteries<\/a>.<\/p>\n

To safeguard against this type of failure, White developed a second kind of microsphere made of solid polyethylene, an inexpensive and widely available plastic. A small quantity of these spheres embedded in the anode and other battery components can function as a safety cutoff switch. If the temperature inside the Fujitsu lifebook n6210 battery<\/a> rises above 105\u00b0 Celsius, the spheres melt into a thin layer of insulating material that shuts off the flow of electricity, preventing a conflagration.<\/p>\n

\u201cWe\u2019ve tested this in real batteries,\u201d said White, whose research is funded by the U.S. Department of Energy. \u201cIt works beautifully.\u201d This safety feature, he said, could be useful for the electric cars emerging on the market.<\/p>\n

\u201cLithium-ion batteries will continue to be the technology used for the next 10 to 15 years in electric cars,\u201d said Kristin Persson of Lawrence Berkeley National Laboratory in California, who is looking for new battery<\/a> materials that not only have better energy storage but also avoid some of the pitfalls of traditional batteries. \u201cIt will take at least that amount of time to develop new materials.\u201d<\/p>\n
