Saindy Pyles thought she was going to die with her baby son, Liam, clutched to her chest as she flew home to Wichita from Miami after photographing a wedding. Midway through the flight Pyles said smoke filled the cabin after she saw sparks and fire burst from a bag in the seat directly behind her. "Honestly, I thought we were going to die," she said. "I looked and all I saw was flashes, just like flashes. I'm like, 'Oh my God, like, what is that?' And [the owner of the bag] is like, 'I don't know. I don't know.'" "Then...

Electric vehicles (EVs) are all the rage. They are touted as a cleaner and more sustainable alternative to gasoline-powered vehicles. The United States government has passed numerous legislative actions to phase out gas-powered vehicles and make sure that, within the near term, all vehicles are electric. The common belief is that electric vehicles are more environmentally friendly and, in general, a safer form of energy. The dark secret: neither are true. Currently the gold standard for all major electronic products, EV’s included, are batteries which are made of lithium-ion. The inventor of lithium-ion himself, after receiving the Nobel Prize, warned...

With the number of fires caused by lithium batteries soaring across the U.S., firefighters and other experts say the training needed to fight them effectively is lagging in many places. Firefighters and city officials are also imploring the manufacturers to redesign the batteries so that, when they fail, the resulting fires can be put down more easily. Kerber said his team has run tests on lithium-ion batteries in which it took only 15 seconds from the first sign of smoke to the windows being blown out in a house. In a traditional fire, it typically takes about three minutes for...

Single crystals of cathode material: (A) no internal boundaries and (B) internal boundaries visible. Credit: Argonne National Laboratory Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory have a long history of breakthrough discoveries with lithium-ion batteries. Many of these discoveries have focused on a battery cathode known as NMC, a nickel-manganese-cobalt oxide. Batteries with this cathode now power the Chevy Bolt. Argonne researchers have made another breakthrough with the NMC cathode. The team's new structure for the cathode's micro-sized particles could lead to longer-lasting and safer batteries able to operate at very high voltage and power vehicles...

One day after officials touted the passage of the Connecticut Clean Air Act, including plans for thousands of electric vehicles to hit the road, one of the state-run electric buses caught on fire over the weekend. The blaze engulfed a CTtransit bus in a Hamden parking lot Saturday morning, sending two workers and a firefighter to the hospital, officials said. “Lithium ion battery fires are difficult to extinguish due to the thermal chemical process that produces great heat and continually reignites,” Hamden fire officials said. Two transit workers were hospitalized as a precaution after being exposed to the smoke. A...

resident Joe Biden and Transportation Secretary Pete Buttigieg were roundly mocked by conservatives last week for suggesting that working-class Americans struggling to pay the ever-climbing prices at the pump should consider simply buying an electric vehicle instead. It was the Biden-era equivalent of Marie Antoinette’s (admittedly apocryphal) adage, “Let them eat cake.” Yet this simple solution floated by Democrat elites might just be even more fantastical than expecting average Americans to be in the financial position to switch to an EV as they struggle to afford groceries. Turns out, the U.S. doesn’t only rely on Russia for oil imports —...

Firefighters are struggling to extinguish a fire that broke out last week on a cargo ship that is carrying thousands of luxury cars and is adrift off the coast of Portugal's Azores islands. A port official said it was unclear when crews would succeed. The vessel, Felicity Ace, which is carrying about 4,000 vehicles including Porsches, Audis and Bentleys, some electric with lithium-ion batteries, caught fire in the middle of the Atlantic Ocean on Wednesday. The 22 crew members on board were evacuated on the same day. "The intervention [to put out the blaze] has to be done very slowly,"...

A new paper presents a stable lithium-metal battery design for the first time. Lithium-ion batteries have flaws that lithium-metal batteries could fix. This new battery adds a self-healing technology that will close cracks where dendrites form. Lithium-ion batteries are the backbone of most of today’s electronic devices, including electric vehicles. But for all of their game-changing benefits, the batteries still have an inherent flaw: dendrites. These thin, snaking, tree-like pieces of lithium form sharp points and end up piercing the battery, causing short circuits and other problems. This ultimately shortens the lifespan of lithium-ion batteries, and leaves major room for...

Researchers have been in a race to find ways to improve lithium-ion batteries. They are also looking to develop alternatives to the lithium-ion battery that would be lower cost and more sustainable to manufacture. And they may just have found one. Aluminum-based batteries would be cheaper to make, because aluminum is the third most abundant element in the Earth’s crust after oxygen and silicon. Aluminum is also light-weight and could be ideal for use in batteries.
