The Mystery Behind Donut Lab's "Impossible" Battery. My wife and I are loving our Roborock Saros 20. If you’d like 13 - 14% off a Roborock Saros 20 and Saros 20X from March 23 - 29, the Roborock Saros 20 is available on Roborock (US) bit.ly/4bI2gac (Canada) bit.ly/419pcZL and Amazon (US) amzn.to/3PicXYg (Canada) amzn.to/4cN4ZjF, and the customized Roborock Saros 20X package available at Target bit.ly/3NtDHEB and Best Buy bestbuy.7tiv.net/oNqZPe comes with one pair of mop cloths and one 200ml cleaning solution in addition to Saros 20!
Ever since Donut Lab announced their miracle solid-state battery, the internet has been absolutely certain about what it is. A capacitor. Vaporware. A scam. Except when you actually dig into those explanations, a lot of them start falling apart. Here's what Donut Lab is actually claiming: more energy per pound than today's best lithium cells. No lithium. No cobalt. No hard-to-get metals. And a battery that charges in five minutes, but lasts a lifetime. Some experts say those specs are physically impossible. Others think they've already cracked the case and figured out who really built this thing and what's actually inside. We don't know yet if Donut Lab's claims will hold up. They’ve been releasing third-party tests slowly over the past few weeks. But let's take a closer look at what this battery could be… what it probably isn't... and what Donut Lab could possibly gain by exaggerating its claims. It’s not as clear-cut as you might think.
