Breakthrough lithium-ion battery can recharge 1,000x faster than current tech

University of Illinois at Urbana-Champaign have created a new lithium-ion battery that has pretty incredible power characteristics, at least in the lab. It can be charged and discharged about 1,000 faster than current lithium-ion batteries, even beating many supercapacitors. But before we uncork the Champagne and imagine driving electric cars with 1,000 miles of range, I must stress that what's incredible about this battery is the power density. The energy density isn't. So you would get much faster charging if you have the "fat pipes" to deliver that much power, but not necessarily a longer driving range. © IU Still, it's an important breakthrough that could help improve batteries, especially if it can be combined with other technologies to improve energy density. Or maybe this type of battery can be used in parallel with more energy-dense batteries to offer more flexibil...
