Stable "Superoxide" Opens the Door to a New Class of Batteries

While lithium-ion batteries have transformed our everyday lives, researchers are currently trying to find new chemistries that could offer even better energy possibilities. One of these chemistries, lithium-air, could promise greater energy density but has certain drawbacks as well. Thanks to research at the U.S. Department of Energy's (DOE's) Argonne National Laboratory, however, one of those drawbacks may have been overcome.
