Get this: Russian scientists have figured out how to make EV batteries way more powerful and longer-lasting by tweaking the inside of the battery cathode. They added a special gradient of metals and even threw in tantalum to keep everything stable. The result? Batteries that degrade half as fast, which means your future electric car (or phone!) could last way longer between charges. Real-world tests are next, but this could be a total game-changer for electric vehicles and clean energy! #Science #EVs #BatteryBreakthrough
