Aluminum battery offers safe alternative to conventional batteries

Stanford University Professor Hongjie Dai and colleagues have developed the first high-performance aluminum battery that’s fast charging, long lasting and inexpensive. The flexible, non-flammable device produces 2 volts of electricity. The research team was able to generate 5 volts - enough to power a smartphone - using two aluminum batteries and a converter. In this video, graduate student Ming Gong and postdoctoral scholar Yingpeng Wu demonstrate how the new technology could offer a safe alternative to l
