Researchers at the University of Illinois at Chicago have taken a step closer towards the development of a battery that could outperform the lithium-ion technology used in electric cars. The team of researchers have replaced lithium ions, each of which carries a single positive charge, with magnesium ions, which have a plus-two charge, in battery-like chemical reactions, using an electrode with a structure that is similar to those in many of today's devices.

Researchers the University of Wisconsin–Madison and Brookhaven National Laboratory have developed a novel X-ray imaging technique to study the electrochemical reactions in lithium-ion rechargeable batteries containing iron fluoride which can store three times the energy of existing batteries. “Iron fluoride has the potential to triple the amount of energy a conventional lithium-ion battery can store,” explained Song Jin, a UW–Madison professor of chemistry and Wisconsin Energy Institute affiliate. “However, we have yet to tap its true potential.”
