A new ultra-thin protective film—thinner than a human hair—could be the game-changer for lithium-metal batteries in electric vehicles. Developed at Korea University, this tech uses silver ions to stop dendrite growth, a major cause of battery failure. With 2,000 hours of cycling and 96% capacity retention, could this innovation finally make EV batteries safer and longer-lasting? Would you trust your next ride with this breakthrough? Let’s debate! #Tech #EVTech #BatteryInnovation
