Iron triflouride could make better electric-car batteries

Adding oxygen and cobalt to the cathode prevents lithium from breaking chemical bonds Enlarge Photo Researchers at the University of Maryland, in conjunction with Brookhaven National Laboratory have developed a new battery cathode material that they say could triple the energy density of lithium-ion batteries. The new material is an engineered variety of iron trifluoride, a well-known material that has had problems with rechargeability and low power production. In an article in the journal Nature Communications (via ChargedEVs ), the researchers revealed how they took iron trifluoride's inherent ability to absorb more lithium ions and added cobalt and oxygen to iron-trifluoride nano rods to make the material absorb and release lithium ions more quickly and readily.
