Lithium-ion batteries power many rechargeable devices that are part of our modern lives: cell phones, laptops, vapes, cordless power tools and electric vehicles of all kinds, from cars to scooters to e-bikes to hoverboards. They’re small, lightweight and powerful but they’re also prone to overheating and catching fire, said Michael Pecht, a professor of engineering at the University of Maryland. “Ever since lithium-ion batteries started to be popular in products, we’ve seen fires, ” he said. At issue is the high density of the batteries, which is a double-edged sword, said Pecht, who also serves as director of the Center for Advanced Life Cycle Engineering, a university research center that consults with companies on reliability and safety issues, including batteries. “They can provide a lot of power to our cell phones and to our computers for a relatively long period of time in a very small volume, ” he said. “But because we have so much energy packed in that small volume, if there is a problem, then they’re very flammable. ” Defects or contamination in the manufacturing process can eventually lead to short circuiting or other failures. There’s not currently much regulation of e-bikes and scooters. But fire officials add that. you should charge your device away from flammable materials like furniture and pillows, and that you shouldn’t charge or stor
