Reza Montazami, an Iowa State University assistant professor of mechanical engineering and an associate of the U.S. Department of Energy’s Ames Laboratory, has been working on transient technology for years. The latest development from his lab is a self-destructing, lithium-ion battery capable of delivering 2.5 volts and dissolving or dissipating in 30 minutes when dropped in water. The battery can power a desktop calculator for about 15 minutes. Read More...
