Ultra-fast charging batteries that can be 70% recharged in just two minutes -- ScienceDaily Noticed via Gizmodo: New Li-Ion Batteries Charge 70 Percent in 2 Minutes, Last for 20 Years "A team of researchers in Singapore have developed a next generation lithium-ion battery that can recharge a battery to 70-percent in just two minutes. That means it would charge an entire electric car in just 15 minutes. And here's the kicker: it lasts over 20 years. Normally, it's safe to be skeptical about new battery technology, but there's something rather hopeful about this breakthrough. The new battery isn't altogether new. It's actually just an improvement upon existing lithium-ion technology."
