El avance de China en baterías de sodio acaba de dejar obsoleto al litio.

China's breakthrough in sodium batteries has just rendered lithium obsolete. The sodium battery that the entire industry considered impossible has just entered mass production. CATL, the world's largest battery manufacturer, launched a cell without lithium or cobalt, boasting a lifespan that shouldn't be possible at this price: over 10,000 full charge cycles. This represents roughly three times the lifespan of your current car's lithium battery. It charges to 80% in 15 minutes. It maintains 90% of its capacity at -40 degrees Celsius, the temperature at which a typical electric vehicle barely functions. And it costs less than a third of what it costs to produce lithium cells. This isn't a prediction. It's already happening. By the end of this video, you'll understand exactly how CATL achieved this and what it means for all the battery-powered devices in your life. Subscribe so you don't miss what's coming. There's a 30-year story behind this battery. Right now, as you're reading this, you have a lithium battery within easy reach. Your phone. Your laptop.
