In recent years, lithium ion batteries that power our phones, our laptops and our Tesla's have exploded, causing serious injury and, in a few cases, death. But a California based company says they've developed a new type of battery that won't explode no matter what you do to it. Mhm battery fires are rare about one in 10 million, but with billions of batteries produced every year, the stakes are higher than you think. Electric cars and e bike sales continue to grow rapidly, and we're likely to see more massive batteries being used to store renewable energy for homes. The technical term for how most battery fires start is thermal runaway, and it works kind of like this. If this banana were a standard lithium ion battery, there's just a thin separation between the parts that carry positive and negative charges. When that barrier is broken, a battery can become a bomb. A new technology is like a bomb squad inside the battery, stopping a fire before it starts. AM Ionics invented a technology called safe core. It's a fuse that goes within the battery cell itself. Safe core adds an additional layer, kind of like placing this deflated balloon between the banana skin and tin foil layer, which represents the current collector. If a battery fails, safe core creates a physical gap to safely stop the flow of electricity. Safe core was originally developed for batteries that soldiers used to power their communications equipment. That's why it needed to be bullets safe if somebody was wearing that be on fire right now, Safe course starts with this black goo. It hardens and then gets rolled out as an additional layer inside the battery. Um, Ionic says that safe core has the potential to quickly scale across the industry because many battery making factories already have the equipment to process the safe course slurry. We can tack, transfer and have battery manufacturers up running within six months. The company recently announced a partnership with Stanley Black and Decker, one of the world's top producers of power tools. Companies have a financial incentive to make sure their batteries are safe. We literally we add pennies to the bill of material. The cost is relatively little to implement the technology in 2016, Samsung recalled 2.5 million phones after several reports of fire. Officially, the company claimed $5 billion in losses. Exploding batteries are a really key safety problem, and it's a terrible impact on their brand. Lithium ion batteries are poised to remain the go to power source in coming years with that many batteries and maybe impossible to completely eliminate the risk of fires. But, um, Ionics believes that they're battle tested. Technology can get the risk that much closer to zero.
